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 than 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.
