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.
