Net::LDAP::Control::PostRead(3)      User Contributed Perl Documentation     Net::LDAP::Control::PostRead(3)



NAME
       Net::LDAP::Control::PostRead - LDAPv3 Post-Read control object

SYNOPSIS
        use Net::LDAP;
        use Net::LDAP::Control::PostRead;
        use Net::LDAP::Constant qw( LDAP_CONTROL_POSTREAD LDAP_SUCCESS );

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

        $postread = Net::LDAP::Control::PostRead->new( attrs => [ qw/givenName/ ] );

        my $mesg = $ldap->modify( "cn=Barbara Jensen, o=University of Michigan, c=US",
                                  replace => { givenName => "Babs" },
                                  control => $postread );

        if ($mesg->code eq LDAP_SUCCESS) {
          my ($afterwards) = $mesg->control( LDAP_CONTROL_PREREAD );
          my $entry = $afterwards ? $afterwards->entry() : undef;

          if ($entry) {
            print "givenName changed to '" .
                  join("', '", $entry->get_value(givenName") .
                  "' to 'Babs'\n");
          }
        }

DESCRIPTION
       "Net::LDAP::Control::PostRead" provides an interface for the creation and manipulation of objects
       that represent the "Post-Read Controls" as described by RFC 4527.

       In modification operations, the "Post-Read request control" indicates to the server that a copy of
       the modified entry after the update is to be returned.  After the successful completion of the
       operation, the accompanying "Post-Read response control" allows one to retrieve the updated value
       from the servers's response.

       One use case of this control may be to obtain values of operational attributes, such as the
       "entryUUID" and "modifyTimestamp" attributes, updated by the server as part of the update operation.

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

       attrs => [ ATTR, ... ]
           A list of attributes to be returned in the entry returned in the response control.

           If absent, all attributes are returned.

           Operational attributes may be included in the list by explicitly asking for them or by using
           special "+" feature (provided the server supports this feature).

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.

       In addition to these methods, the control also supports the following method:

       entry ()
           Returns the entry from the response control in the response message to the LDAP request that
           contained the request control.

           The result is either a Net::LDAP::Entry object or undefined.
