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 cqrequired 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.
