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.
