LWP::Protocol::ldap - Provide LDAP support for LWP::UserAgent
$ua = LWP::UserAgent->new();
$res = $ua->get('ldap://ldap.example.com/' .
Accept => 'text/json'):
The LWP::Protocol::ldap module provides support for using ldap
URLs following RFC 4516
This module is a plug-in to the LWP
protocol handling, so you don't use it directly.
In addition to being used with LDAP URIs, LWP::Protocol::ldap also acts
as the base class for its sibling modules LWP::Protocol::ldaps
HTTP methods supported
LWP::Protocol::ldap implements the HTTP GET and HEAD methods.
They are mapped to the LDAP search operation,
Depending on the HTTP Accept header provided by the user agent,
LWP::Protocol::ldap can answer the requests in one of the following
When the HTTP Accept header contains the "text/dsml" MIME type,
the response is sent as DSMLv1.
When the HTTP Accept header contains the "text/json" MIME type,
the response is sent as JSON.
For this to work the JSON Perl module needs to be installed.
When the HTTP Accept header contains the "text/ldif" MIME type,
the response is sent in LDIFv1 format.
In case no HTTP Accept header has been sent or none of the above
MIME types can be detected, and the x-format extension has not been provided
either, the response is sent using HTML markup in a 2-column table format
(roughly modeled on LDIF).
As an alternative to sending an HTTP Accept header, LWP::Protocol::ldap
also accepts the "x-format" extension
For ldap and ldapi URIs, the module implements the "x-tls" extension
that switches the LDAP connection to TLS using a call of the
In the above example, ideally giving "x-tls" should be sufficient,
but unfortunately the parser in URI::ldap has a little flaw.
Usually the connection is done anonymously, but if the HTTP Authorization
header is provided with credentials for HTTP Basic authorization,
the credentials given in that header will be used to do a simple
bind to the LDAP server.
