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


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

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

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

 @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;



Net::LDAP::Control::ProxyAuth provides an interface for the creation and manipulation of objects that represent the proxyauthorisationControl as described by draft-weltman-ldapv3-proxy-XX.txt.


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


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


In older versions of 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 proxyauthorisationControl.

Please note: Unfortunately the OID and the encoding or the proxyauthorisationControl changed significantly in recent versions of draft-weltman-ldapv3-proxy-XX.txt. 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.


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.


Net::LDAP, Net::LDAP::Control,


Olivier Dubois, Swift sa/nv based on Net::LDAP::Control::Page from Graham Barr <>. Peter Marschall <> added authzID extensions based on ideas from Graham Barr <>.
