NAME ^

Net::LDAP::Control::ProxyAuth - LDAPv3 Proxy Authorization control object

SYNOPSIS ^

 use Net::LDAP;
 use Net::LDAP::Control::ProxyAuth;

 $ldap = Net::LDAP->new( "ldap.mydomain.eg" );

 $auth = Net::LDAP::Control::ProxyAuth->new( authzID => 'dn:cn=me,ou=people,o=myorg.com' );

 @args = ( base     => "cn=subnets,cn=sites,cn=configuration,$BASE_DN",
           scope    => "subtree",
           filter   => "(objectClass=subnet)",
           callback => \&process_entry, # Call this sub for each entry
           control  => [ $auth ],
 );

 while (1) {
   # Perform search
   my $mesg = $ldap->search( @args );

   # Only continue on LDAP_SUCCESS
   $mesg->code and last;

 }

DESCRIPTION ^

Net::LDAP::Control::ProxyAuth provides an interface for the creation and manipulation of objects that represent the Proxy Authorization Control as described by RFC 4370.

It allows a client to be bound to an LDAP server with its own identity, but to perform operations on behalf of another user, the authzID.

With the exception of any extension that causes a change in authentication, authorization or data confidentiality, a single Proxy Authorization Control may be included in any search, compare, modify, add, delete, or moddn or extended operation.

As required by the RFC, the criticality of this control is automatically set to TRUE in order to protect clients from submitting requests with other identities that they intend to.

CONSTRUCTOR ARGUMENTS ^

In addition to the constructor arguments described in Net::LDAP::Control the following are provided.

authzID

The authzID that is required. This is the identity we are requesting operations to use.

proxyDN

In early versions of the drafts to RFC 4370, draft-weltman-ldapv3-proxy-XX.txt, the value in the control and thus the constructor argument was a DN and was called proxyDN. It served the same purpose as authzID in recent versions of proxyAuthorization control.

Please note: Unfortunately the OID and the encoding or the Proxy Authorization Control changed significantly between early versions of draft-weltman-ldapv3-proxy-XX.txt and the final RFC. Net::LDAP::Control::ProxyAuth tries to cope with that situation and changes the OID and encoding used depending on the constructor argument.

With proxyDN as constructor argument the old OID and encoding are used, while with authzID as constructor argument the new OID and encoding are used. Using this logic servers supporting either OID can be handled correctly.

METHODS ^

As with Net::LDAP::Control each constructor argument described above is also available as a method on the object which will return the current value for the attribute if called without an argument, and set a new value for the attribute if called with an argument.
