.SH DESCRIPTION
.IX Header "DESCRIPTION"
The LWP::Protocol::ldap module provides support for using \fIldap\fR 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.
.PP
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.
.SS Features
.IX Subsection "Features"
\fIHTTP methods supported\fR
.IX Subsection "HTTP methods supported"
.PP
LWP::Protocol::ldap implements the HTTP \fIGET\fR and \fIHEAD\fR methods.
They are mapped to the LDAP search operation,
.PP
\fIResponse format\fR
.IX Subsection "Response format"
.PP
Depending on the HTTP \fIAccept\fR header provided by the user agent,
LWP::Protocol::ldap can answer the requests in one of the following
formats:
.IP DSML 4
.IX Item "DSML"
When the HTTP \fIAccept\fR header contains the \f(CW\*(C`text/dsml\*(C'\fR MIME type,
the response is sent as DSMLv1.
.IP JSON 4
.IX Item "JSON"
When the HTTP \fIAccept\fR header contains the \f(CW\*(C`text/json\*(C'\fR MIME type,
the response is sent as JSON.
For this to work the \fIJSON\fR Perl module needs to be installed.
.IP LDIF 4
.IX Item "LDIF"
When the HTTP \fIAccept\fR header contains the \f(CW\*(C`text/ldif\*(C'\fR MIME type,
the response is sent in LDIFv1 format.
.IP HTML 4
.IX Item "HTML"
In case no HTTP \fIAccept\fR header has been sent or none of the above
MIME types can be detected, and the \fIx\-format\fR extension has not been provided
either, the response is sent using HTML markup in a 2\-column table format
(roughly modeled on LDIF).
.PP
As an alternative to sending an HTTP \fIAccept\fR header, LWP::Protocol::ldap
also accepts the \f(CW\*(C`x\-format\*(C'\fR extension
.PP
Example:
.PP
.Vb 1
\& ldap://ldap.example.com/o=University%20of%20Michigan,c=US??sub?(cn=Babs%20Jensen)?x\-format=dsml
.Ve
.PP
\fITLS support\fR
.IX Subsection "TLS support"
.PP
For \fIldap\fR and \fIldapi\fR URIs, the module implements the \f(CW\*(C`x\-tls\*(C'\fR extension
that switches the LDAP connection to TLS using a call of the
start_tls method.
.PP
Example:
.PP
.Vb 1
\& ldap://ldap.example.com/o=University%20of%20Michigan,c=US??sub?(cn=Babs%20Jensen)?x\-tls=1
.Ve
.PP
Note:
In the above example, ideally giving \f(CW\*(C`x\-tls\*(C'\fR should be sufficient,
but unfortunately the parser in URI::ldap has a little flaw.
.PP
\fIAuthorization\fR
.IX Subsection "Authorization"
.PP
Usually the connection is done anonymously, but if the HTTP \fIAuthorization\fR
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.
