LWP::Protocol::ldap - Provide LDAP support for LWP::UserAgent


  use LWP::UserAgent;

  $ua = LWP::UserAgent->new();
  $res = $ua->get('ldap://' .
                   Accept => 'text/json'):


The LWP::Protocol::ldap module provides support for using ldap schemed URLs following RFC 4516 with LWP. 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 and LWP::Protocol::ldapi.


HTTP methods supported

LWP::Protocol::ldap implements the HTTP GET and HEAD methods. They are mapped to the LDAP search operation,

Response format

Depending on the HTTP Accept header provided by the user agent, LWP::Protocol::ldap can answer the requests in one of the following formats:


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



TLS support

For ldap and ldapi URIs, the module implements the x-tls extension that switches the LDAP connection to TLS using a call of the start_tls method.



Note: 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.
