NAME ^

Net::LDAPapi - Perl5 Module Supporting LDAP API

SYNOPSIS ^

  use Net::LDAPapi;

  See individual items and Example Programs for Usage

DESCRIPTION ^

  This module allows Perl programmers to access and manipulate an LDAP
  based Directory.

  Versions beginning with 1.40 support both the original "C API" and
  new "Perl OO" style interface methods.  With version 1.42, I've added
  named arguments.

THE INTIAL CONNECTION ^

  All connections to the LDAP server are started by creating a new
  "blessed object" in the Net::LDAPapi class.  This can be done quite
  easily by the following type of statement.

  $ld = new Net::LDAPapi($hostname);

  Where $hostname is the name of your LDAP server.  If you are not using
  the standard LDAP port (389), you will also need to supply the
  portnumber.

  $ld = new Net::LDAPapi($hostname, 15555);

  The new method can also be called with named arguments.

  $ld = new Net::LDAPapi(-host=>$hostname, -port=>15389);

  Instead of the above mentioned argumens -url can be used in the
  following form

  $ld = new Net::LDAPapi(-url=>"ldap://host:port");

  Setting -debug=>"TRUE" will enable more verbose error messages.

  Note that with named arguments, the order of the arguments is
  insignificant.

CONTROLS ^

  In LDAP v3 controls are an additional piece of data, which can be
  submitted with most of the requests to the server and returned back
  attached to the result.  Controls, passed to the call, are separated
  in two types.  The client side controls, which are not passed to the
  server and are of not much use.  They are denoted by -cctrls named
  parameter.  The server side controls, denoted by -sctrls named
  parameter are actually passed to the server and may affect its
  operation or returned results.  Each entry of the result may have
  controls attached to it as well ( see parse_entry(...) call ).

  -cctrls and -sctrls must be reference to array of controls.

  To create control call create_control(...) method. Bellow is an
  example of creating valsort control.

  my $asn = Convert::ASN1->new;
  $asn->prepare('SEQUENCE { b BOOLEAN }');
  my $berval = $asn->encode(b=>1); # or 1

  my $ctrl =
    $ld->create_control(-oid=>Net::LDAPapi::LDAP_CONTROL_VALSORT,
                        -berval=>$berval,
                        -critical=>Net::LDAPapi::CRITICAL);

  The control is to be freed by calling free_control($ctrl).

  If contol is attached to results entry, it can be retrieved by
  calling parse_result($entry). If no entry is passed to
  parse_result(...) then current entry is used. It returns hash
  with following keys

  Key           Value
  -------------------
  matcheddn     string
  errmsg        string
  referrals     array reference
  serverctrls   array reference

  You can look into content of the control by using get_contol_XXX
  functions like this:

  local %parsed = $ld->parse_result($entry);
  local $serverctrls = $parsed{"serverctrls"};
  local @sctrls = @$serverctrls;
  if( scalar(@sctrls) > 0 ) {
    foreach $ctrl (@sctrls) {
      print "\nreceived control\n";
      print "oid = ".$ld->get_control_oid($ctrl)."\n";
      print "berval = ".$ld->get_control_berval($ctrl)."\n";
      print "critical = ".$ld->get_control_critical($ctrl)."\n";
    }
  }

BINDING ^

  After creating a connection to the LDAP server, you may need to
  bind to the server prior to performing any LDAP related functions.
  This can be done with the 'bind' methods.

  An anonymous bind can be performed without arguments:

  $status = $ld->bind_s;

  A simple bind can be performed by specifying the DN and PASSWORD of
  the user you are authenticating as:

  $status = $ld->bind_s($dn, $password);

  Note that if $password above was "", you would be doing a reference
  bind, which would return success even if the password in the
  directory was non-null.  Thus if you were using the bind to check a
  password entered with one in the directory, you should first check
  to see if $password was NULL.

  To perform SASL bind fill in appropriate parameters calling
  sasl_params(...) and call

  $status = $ld->bind_s(-type=>LDAP_AUTH_SASL)

  Bellow is an example of GSSAPI K5 bind parameters.

  $ld->sasl_parms(-mech=>"GSSAPI", -realm=>"domain.name.com",
                  -authzid=>"",    -secprops=>"",
                  -flags=>LDAP_SASL_QUIET);

  For all of the above operations, you could compare $status to
  LDAP_SUCCESS to see if the operation was successful.

  Additionally, you could use 'bind' rather than 'bind_s' if you wanted
  to use the Asynchronous LDAP routines.  The asynchronous routines
  would return a MSGID rather than a status.  To find the status of an
  Asynchronous bind, you would need to first obtain the result with a
  call to $ld->result.  See the entry for result later in the man page,
  as well as the 'ldapwalk.pl' example for further information on
  obtaining results from Asynchronous operations.

  The bind operations can also accept named arguments.

  $status = $ld->bind_s(-dn=>$dn,
                        -password=>$password,
                        -type=>LDAP_AUTH_SIMPLE);

  As with all other commands that support named arguments, the order of
  the arguments makes no difference.

GENERATING AN ADD/MODIFY HASH ^

  For the add and modify routines you will need to generate
  a list of attributes and values.

  You will do this by creating a HASH table.  Each attribute in the
  hash contains associated values.  These values can be one of three
  things.

    - SCALAR VALUE    (ex. "Clayton Donley")
    - ARRAY REFERENCE (ex. ["Clayton Donley","Clay Donley"])
    - HASH REFERENCE  (ex. {"r",["Clayton Donley"]}
         note:  the value inside the HASH REFERENCE must currently
             be an ARRAY REFERENCE.

  The key inside the HASH REFERENCE must be one of the following for a
  modify operation:
    - "a" for LDAP_MOD_ADD (Add these values to the attribute)
    - "r" for LDAP_MOD_REPLACE (Replace these values in the attribute)
    - "d" for LDAP_MOD_DELETE (Delete these values from the attribute)

  Additionally, in add and modify operations, you may specify "b" if the
  attributes you are adding are BINARY (ex. "rb" to replace binary).

  Currently, it is only possible to do one operation per add/modify
  operation, meaning you can't do something like:

     {"d",["Clayton"],"a",["Clay"]}   <-- WRONG!

  Using any combination of the above value types, you can do things like:

  %ldap_modifications = (
     "cn", "Clayton Donley",                    # Replace 'cn' values
     "givenname", ["Clayton","Clay"],           # Replace 'givenname' values
     "mail", {"a",["donley\@cig.mcel.mot.com"],  #Add 'mail' values
     "jpegphoto", {"rb",[$jpegphotodata]},      # Replace Binary jpegPhoto
  );

  Then remember to call the add or modify operations with a REFERENCE to
  this HASH.  Something like:

  $ld->modify_s($modify_dn,\%ldap_modifications);

GETTING/SETTING LDAP INTERNAL VALUES ^

  The following methods exist to obtain internal values within a
  Net::LDAPapi object:

  o errno - The last error-number returned by the LDAP library for this
    connection.
          ex:  print "Error Number: " . $ld->errno . "\n";

  o errstring - The string equivalent of 'errno'.
          ex:  print "Error: " . $ld->errstring . "\n";

  o ld - Reference to the actual internal LDAP structure.  Only useful if
    you needed to obtain this pointer for use in non-OO routines.
          ex:  $ldptr = $ld->ld;

  o entry - Reference to the current entry.  Not typically needed, but method
    supplied, just in case.
          ex:  $entry = $ld->entry;

  o msgid - Get msgid from an LDAP Result.
          ex:  $msgid = $ld->msgid;  #  msgid of current result
          ex:  $msgid = $ld->msgid($result) # msgid of $result

  o msgtype - Get msgtype from an LDAP Result.
      ex:  $msgtype = $ld->msgtype;  # msgtype of current result
          ex:  $msgtype = $ld->msgtype($result) # msgtype of $result

  These methods are only useful for GETTING internal information, not setting
  it.  No methods are currently available for SETTING these internal values.

GETTING AND SETTING LDAP SESSION OPTIONS ^

  The get_option and set_option methods can be used to get and set LDAP
  session options.

  The following LDAP options can be set or gotten with these methods:
    LDAP_OPT_DEREF - Dereference
    LDAP_OPT_SIZELIMIT - Maximum Number of Entries to Return
    LDAP_OPT_TIMELIMIT - Timeout for LDAP Operations
    LDAP_OPT_REFERRALS - Follow Referrals

  For both get and set operations, the first argument is the relivant
  option.  In get, the second argument is a reference to a scalar variable
  that will contain the current value of the option.  In set, the second
  argument is the value at which to set this option.

  Examples:
    $ld->set_option(LDAP_OPT_SIZELIMIT,50);
    $ld->get_option(LDAP_OPT_SIZELIMIT,\$size);

  When setting LDAP_OPT_REFERRALS, the second argument is either LDAP_OPT_ON
  or LDAP_OPT_OFF.  Other options require a number.

  Both get_option and set_option return 0 on success and non-zero otherwise.

SSL SUPPORT ^

  When compiled with the Mozilla SDK, this module now supports SSL.
  I do not have an SSL capable server, but I'm told this works.  The
  functions available are:

  o ssl - Turn on SSL for this connection.
    Install I/O routines to make SSL over LDAP possible
  o ssl_client_init($certdbpath,$certdbhandle)
    Initialize the secure parts (called only once)

  Example:
    $ld = new Net::LDAPapi("host",LDAPS_PORT);
    $ld->ssl_client_init($certdbpath,$certdbhandle);
    $ld->ssl;

SETTING REBIND PROCESS ^

  As of version 1.42, rebinding now works properly.

  The set_rebind_proc method is used to set a PERL function to supply DN,
  PASSWORD, and AUTHTYPE for use when the server rebinds (for referals,
  etc...).

  Usage should be something like:
    $rebind_ref = \&my_rebind_proc;
    $ld->set_rebind_proc($rebind_ref);

  You can then create the procedure specified.  It should return 3 values.

  Example:
    sub my_rebind_proc
    {
       return($dn,$pass,LDAP_AUTH_SIMPLE);
    }

SUPPORTED METHODS ^

abandon MSGID SCTRLS CCTRLS
  This cancels an asynchronous LDAP operation that has not completed.  It
  returns an LDAP STATUS code upon completion.

  Example:

    $status = ldap_abandon($ld, $msgid); # XXX fix this
add DN ATTR SCTRLS CCTRLS
  Begins an an asynchronous LDAP Add operation.  It returns a MSGID or undef
  upon completion.

  Example:

    %attributes = (
       "cn", ["Clayton Donley","Clay Donley"] #Add Multivalue cn
       "sn", "Donley",                #Add sn
       "telephoneNumber", "+86-10-65551234",  #Add telephoneNumber
       "objectClass", ["person","organizationalPerson"],
                        # Add Multivalue objectClass
       "jpegphoto", {"b",[$jpegphoto]},  # Add Binary jpegphoto
    );

    $entrydn = "cn=Clayton Donley, o=Motorola, c=US";

    $msgid = $ld->add($entrydn, \%attributes);

  Note that in most cases, you will need to be bound to the LDAP server
  as an administrator in order to add users.
add_s DN ATTR SCTRLS CCTRLS
  Synchronous version of the 'add' method.  Arguments are identical
  to the 'add' method, but this operation returns an LDAP STATUS,
  not a MSGID.

  Example:

    $ld->add_s($entrydn, \%attributes);

  See the section on creating the modify structure for more information
  on populating the ATTRIBUTES field for Add and Modify operations.
bind DN PASSWORD TYPE SCTRLS CCTRLS
  Asynchronous method for binding to the LDAP server.  It returns a
  MSGID.

  Examples:

    $msgid = $ld->bind;
    $msgid = $ld->bind("cn=Clayton Donley, o=Motorola, c=US", "abc123");
bind_s DN PASSWORD TYPE SCTRLS CCTRLS
  Synchronous method for binding to the LDAP server.  It returns
  an LDAP STATUS.

  Examples:

    $status = $ld->bind_s;
    $status = $ld->bind_s("cn=Clayton Donley, o=Motorola, c=US", "abc123");
compare DN ATTR VALUE SCTRLS CCTRLS
  Asynchronous method for comparing a value with the value contained
  within DN.  Returns a MSGID or undef.

  Example:

    $msgid = $ld->compare("cn=Clayton Donley, o=Motorola, c=US", \
        $type, $value);
compare_s DN ATTR VALUE SCTRLS CCTRLS
  Synchronous method for comparing a value with the value contained
  within DN.  Returns an LDAP_COMPARE_TRUE, LDAP_COMPARE_FALSE or an error code.

  Example:

    $status = $ld->compare_s("cn=Clayton Donley, o=Motorola, c=US", \
        $type, $value);
count_entries
  Returns the number of entries in an LDAP result chain.

  Example:

    $number = $ld->count_entries;
count_references MSG
  Return number of references in a given/current message.

  Example:

    $number = $ld->count_references
delete DN
  Asynchronous method to delete DN.  Returns a MSGID or -1 if error.

  Example:

    $msgid = $ld->delete("cn=Clayton Donley, o=Motorola, c=US");
delete_s DN
  Synchronous method to delete DN.  Returns an LDAP STATUS.

  Example:

    $status = $ld->delete_s("cn=Clayton Donley, o=Motorola, c=US");
dn2ufn DN
  Converts a Distinguished Name (DN) to a User Friendly Name (UFN).
  Returns a string with the UFN.

  Since this operation doesn't require an LDAP object to work, you
  could technically access the function directly as 'ldap_dn2ufn' rather
  that the object oriented form.

  Example:

    $ufn = $ld->dn2ufn("cn=Clayton Donley, o=Motorola, c=US");
explode_dn DN NOTYPES
  Splits the DN into an array comtaining the separate components of
  the DN.  Returns an Array.  NOTYPES is a 1 to remove attribute
  types and 0 to retain attribute types.

  Can also be accessed directly as 'ldap_explode_dn' if no session is
  initialized and you don't want the object oriented form.

  In OpenLDAP this call is depricated.

  Example:

    @components = $ld->explode_dn($dn, 0);
explode_rdn RDN NOTYPES
  Same as explode_dn, except that the first argument is a
  Relative Distinguished Name.  NOTYPES is a 1 to remove attribute
  types and 0 to retain attribute types.  Returns an array with
  each component.

  Can also be accessed directly as 'ldap_explode_rdn' if no session is
  initialized and you don't want the object oriented form.

  In OpenLDAP this call is depricated.

  Example:

    @components = $ld->explode_rdn($rdn, 0);
first_attribute
  Returns pointer to first attribute name found in the current entry.
  Note that this only returning attribute names (ex: cn, mail, etc...).
  Returns a string with the attribute name.

  Returns an empty string when no attributes are available.

  Example:

    $attr = $ld->first_attribute;
first_entry
  Sets internal pointer to the first entry in a chain of results.  Returns
  an empty string when no entries are available.

  Example:

    $entry = $ld->first_entry;
first_message
   Return the first message in a chain of result returned by the search
   operation. LDAP search operations return LDAPMessage, which is a head
   in chain of messages accessable to the user. Not all all of them are
   entries though. Type of the message can be obtained by calling
   msgtype(...) function.
get_all_entries RESULT
  Returns result of the search operation in the following format
    (HASH)
    dn -> (HASH)
          key -> (ARRAY)

  Example:
    my $all_entries_ref = $ld->get_all_entries;
    my %all_entries = %$all_entries_ref;

    foreach (keys %all_entries) {
        print "<$_> -> <".$all_entries{$_}.">\n";
        $entry = $all_entries{$_};

        local %entry_h = %$entry;
        foreach $k (keys %entry_h) {
            $values = $entry_h{$k};

            print "  <$k> ->\n";
            foreach $val (@$values) {
                print "     <$val>\n";
            }
        }
    }
get_dn MSG
  Returns a string containing the DN for the specified message or an
  empty string if an error occurs. If no message is specified then
  then default entry is used.

  Example:

    $dn = $ld->get_dn;
get_entry_controls MSG
  Returns an array of controls returned with the given entry. If not MSG
  is given as a paramater then current message/entry is used.

  Example:

    my @sctrls = $ld->get_entry_controls($msg);
    foreach $ctrl (@sctrls) {
        print "control oid is ".$self->get_control_oid($ctrl)."\n";
    }
get_values ATTR
  Obtain a list of all values associated with a given attribute.
  Returns an empty list if none are available.

  Example:

    @values = $ld->get_values("cn");

  This would put all the 'cn' values for $entry into the array @values.
get_values_len ATTR
  Retrieves a set of binary values for the specified attribute.

  Example:

    @values = $ld->get_values_len("jpegphoto");

  This would put all the 'jpegphoto' values for $entry into the array @values.
  These could then be written to a file, or further processed.
is_ldap_url URL
  Checks to see if a specified URL is a valid LDAP Url.  Returns 0 on false
  and 1 on true.

  Example:

    $isurl = $ld->is_ldap_url("ldap://x500.my.org/o=Org,c=US");
listen_for_changes BASEDN SCOPE FILTER ATTRS ATTRSONLY TIMEOUT SIZELIMIT COOKIE
  Experimental function which implements syncrepl API in
  refreshAndPersist mode. All but one arguments are the same as in search
  function. Argument 'cookie' is the special one here. It must be specified
  and is a file name in which cookie is to be stored. On a subsequent
  restart of the seach only the newer results will be returned than those
  indicated by the stored cookie. To refresh all entries, one would have to
  remove that file.

  This function is to be used in conjunction with next_changed_entries(...),
  there you will also find example of its usage.
msgfree
  Frees the current LDAP result.  Returns the type of message freed.

  Example:

    $type = $ld->msgfree;
msgtype MSG
  Returns the numeric id of a given message. If no MSG is given as a parameter
  then current message is used. Following types are recognized: LDAP_RES_BIND,
  LDAP_RES_SEARCH_ENTRY, LDAP_RES_SEARCH_REFERENCE, LDAP_RES_SEARCH_RESULT,
  LDAP_RES_MODIFY, LDAP_RES_ADD, LDAP_RES_DELETE, LDAP_RES_MODDN,
  LDAP_RES_COMPARE, LDAP_RES_EXTENDED, LDAP_RES_INTERMEDIATE, LDAP_RES_ANY,
  LDAP_RES_UNSOLICITED.

  Example:

    $type = $ld->msgtype
msgtype2str TYPE
  Returns string representation of a given numeric message type.

  Example:
    print "type = ".$ld->msgtype2str($ld->msgtype)."\n";
modify DN MOD
  Asynchronous method to modify an LDAP entry.  DN is the DN to
  modify and MOD contains a hash-table of attributes and values.  If
  multiple values need to be passed for a specific attribute, a
  reference to an array must be passed.

  Returns the MSGID of the modify operation.

  Example:

    %mods = (
      "telephoneNumber", "",     #remove telephoneNumber
      "sn", "Test",              #set SN to TEST
      "mail", ["me\@abc123.com","me\@second-home.com"],  #set multivalue 'mail'
      "pager", {"a",["1234567"]},  #Add a Pager Value
      "jpegphoto", {"rb",[$jpegphoto]},  # Replace Binary jpegphoto
    );

    $msgid = $ld->modify($entrydn,\%mods);

  The above would remove the telephoneNumber attribute from the entry
  and replace the "sn" attribute with "Test".  The value in the "mail"
  attribute for this entry would be replaced with both addresses
  specified in @mail.  The "jpegphoto" attribute would be replaced with
  the binary data in $jpegphoto.
modify_s DN MOD
  Synchronous version of modify method.  Returns an LDAP STATUS.  See the
  modify method for notes and examples of populating the MOD
  parameter.

  Example:

    $status = $ld->modify_s($entrydn,\%mods);
modrdn2 DN NEWRDN DELETE
  No longer available. Use function 'rename'.
modrdn2_s DN NEWRDN DELETE
  No longer available. Use function 'rename_s'.
next_attribute
  Similar to first_attribute, but obtains next attribute.
  Returns a string comtaining the attribute name.  An empty string
  is returned when no further attributes exist.

  Example:

    $attr = $ld->next_attribute;
next_changed_entries MSGID ALL TIMEOUT
 This function is too be used together with listen_for_changes(...) (see above).
 It returns an array of Entries, which has just changed. Each element in this
 array is a hash reference with two key value pairs, 'entry' which contains usual
 entry and 'state' which contain one of the following strings 'present', 'add',
 'modify' or 'delete'.

 Example:

    my $msgid = $ld->listen_for_changes('', LDAP_SCOPE_SUBTREE, "(cn=Dm*)", NULL, NULL,
                                    NULL, NULL, $cookie);

    while(1) {
        while( @entries = $ld->next_changed_entries($msgid, 0, -1) ) {
            foreach $entry (@entries) {
                print "entry dn is <".$ld->get_dn($entry->{'entry'})."> ".
                    $entry->{'state'}."\n";
            }
        }
    }
next_entry
  Moves internal pointer to the next entry in a chain of search results.

  Example:

    $entry = $ld->next_entry;
next_message
  Moves internal pointer to the next message in a chain of search results.

  Example:

    $msg = $ld->next_message;
parse_result MSG FREEMSG
  This function is used to retrieve auxiliary data associated with the
  message. The return value is a hashtable containing following kevalue
  pairs.
    'errcode'     -> numeric
    'matcheddn'   -> string
    'errmsg'      -> string
    'referrals'   -> array reference
    'serverctrls' -> array reference

  The FREEMSG parameter determines whether the parsed message is freed
  or not after the extraction. Any non-zero value will make it free the
  message. The msgfree() routine can also be used to free the message
  later.
perror MSG
  If an error occurs while performing an LDAP function, this procedure
  will display it.  You can also use the err and errstring methods to
  manipulate the error number and error string in other ways.

  Note that this function does NOT terminate your program.  You would
  need to do any cleanup work on your own.

  Example:

    $ld->perror("add_s");
rename DN NEWRDN NEWSUPER DELETE SCTRLS CCTRLS
  Asynchronous method to change the name of an entry. NEWSUPER is a new
  parent (superior entry).  If set to NULL then only the RDN is changed.
  Set DELETE to non-zero if you wish to remove the attribute values from the
  old name.  Returns a MSGID.

  Example:

    $msgid = $ld->rename("cn=Clayton Donley, o=Motorola, c=US", \
        "cn=Clay Donley", NULL, 0);
rename_s DN NEWRDN NEWSUPER DELETE SCTRLS CCTRLS
  Synchronous method to change the name of an entry. NEWSUPER is a new
  parent (superior entry).  If set to NULL then only the RDN is changed.
  Set DELETE to non-zero if you wish to remove the attribute values from the
  old name.  Returns a LDAP STATUS.

  Example:

    $status = $ld->rename("cn=Clayton Donley, o=Motorola, c=US", \
        "cn=Clay Donley", NULL, 0);
result MSGID ALL TIMEOUT
  Retrieves the result of an operation initiated using an asynchronous LDAP
  call.  It calls internally ldap_result function.  Returns LDAP message or
  undef if error. Return value of ldap_result call stored in $ld->{"status"}
  and is set -1 if something wrong happened, 0 if specified timeout was
  exceeded or type of the returned message.

  MSGID is the MSGID returned by the Asynchronous LDAP call.  Set ALL to
  0 to receive entries as they arrive, or non-zero to receive all entries
  before returning.  Set TIMEOUT to the number of seconds to wait for the
  result, or -1 for no timeout.

  Example:

    $entry = $ld->result($msgid, 0, 1);
    print "msgtype = ".$ld->msgtype2str($ld->{"status"})."\n";
result_entry
  This function is a shortcut for moving pointer along the chain of entries
  in the result. It is used instead of first_entry and next_entry functions.

  Example
    while( $entry = $ld->result_entry ) {
        print "dn = ".$ld->get_dn($entry)."\n";
    }
result_message
  This function is a shortcut for moving pointer along the chain of messages
  in the result. It is used instead of first_message and next_message functions.

  Example
    while( $msg = $ld->result_message ) {
        $msgtype = $self->msgtype($msg);

search BASE SCOPE FILTER ATTRS ATTRSONLY
  Begins an asynchronous LDAP search.  Returns a MSGID or -1 if an
  error occurs.  BASE is the base object for the search operation.
  FILTER is a string containing an LDAP search filter.  ATTRS is a
  reference to an array containing the attributes to return.  An
  empty array would return all attributes.  ATTRSONLY set to non-zero
  will only obtain the attribute types without values.

  SCOPE is one of the following:
        LDAP_SCOPE_BASE
        LDAP_SCOPE_ONELEVEL
        LDAP_SCOPE_SUBTREE

  Example:

    @attrs = ("cn","sn");    # Return specific attributes
    @attrs = ();             # Return all Attributes

    $msgid = $ld->search("o=Motorola, c=US", LDAP_SCOPE_SUBTREE, \
        "(sn=Donley), \@attrs, 0);
search_s BASE SCOPE FILTER ATTRS ATTRSONLY (rewrite XXX)
  Performs a synchronous LDAP search.  Returns an LDAP STATUS.  BASE
  is the base object for the search operation.  FILTER is a string
  containing an LDAP search filter.  ATTRS is a reference to an array
  containing the attributes to return.  An empty array would return all
  attributes.  ATTRSONLY set to non-zero will only obtain the attribute
  types without values.

  SCOPE is one of the following:
        LDAP_SCOPE_BASE
        LDAP_SCOPE_ONELEVEL
        LDAP_SCOPE_SUBTREE

  Example:

    @attrs = ("cn","sn");    # Return specific attributes
    @attrs = ();             # Return all attributes

    $status = $ld->search_s("o=Motorola, c=US",LDAP_SCOPE_SUBTREE, \
        "(sn=Donley)",\@attrs,0);
search_st BASE SCOPE FILTER ATTRS ATTRSONLY TIMEOUT (rewrite/remove XXX)
  Performs a synchronous LDAP search with a TIMEOUT.  See search_s
  for a description of parameters.  Returns an LDAP STATUS.  Results are
  put into RESULTS.  TIMEOUT is a number of seconds to wait before giving
  up, or -1 for no timeout.

  Example:

    $status = $ld->search_st("o=Motorola, c=US",LDAP_SCOPE_SUBTREE, \
        "(sn=Donley),[],0,3);
unbind SCTRLS CCTRLS
  Unbind LDAP connection with specified SESSION handler.

  Example:

    $ld->unbind;
url_parse URL
  Parses an LDAP URL into separate components.  Returns a HASH reference
  with the following keys, if they exist in the URL:

  host      - LDAP Host
  port      - LDAP Port
  dn        - LDAP Base DN
  attr      - LDAP Attributes to Return (ARRAY Reference)
  filter    - LDAP Search Filter
  scope     - LDAP Search Scope
  options   - Mozilla key specifying LDAP over SSL

  Example:

    $urlref = $ld->url_parse("ldap://ldap.my.org/o=My,c=US");
url_search URL ATTRSONLY
  Perform an asynchronous search using an LDAP URL.  URL is the LDAP
  URL to search on.  ATTRSONLY determines whether we are returning
  the values for each attribute (0) or only returning the attribute
  names (1).  Results are retrieved and parsed identically to a call
  to the search method.

  Returns a non-negative MSGID upon success.

  Example:

    $msgid = $ld->url_search($my_ldap_url, 0);
url_search_s URL ATTRSONLY
  Synchronous version of the url_search method.  Results are retrieved
  and parsed identically to a call to the search_s method.

  Returns LDAP_SUCCESS upon success.

  Example:

    $status = $ld->url_search_s($my_ldap_url, 0);
url_search_st URL ATTRSONLY TIMEOUT
  Similar to the url_search_s method, except that it allows a timeout
  to be specified.  The timeout is specified as seconds.  A timeout of
  0 specifies an unlimited timeout.  Results are retrieved and parsed
  identically to a call to the search_st method.

  Returns LDAP_SUCCESS upon success.

  Example:

    $status = $ld->url_search_s($my_ldap_url,0,2);
