=head1 NAME
DJabberd::Authen::LDAP - An LDAP authentication module for DJabberd
=head1 VERSION
Version 0.01
=cut
our $VERSION = '0.01';
=head1 SYNOPSIS
<VHost mydomain.com>
[...]
<Plugin DJabberd::Authen::LDAP>
LDAPURI ldap://localhost/
LDAPBindDN cn=reader
LDAPBindPW pass
LDAPBaseDN ou=people
LDAPFilter (&(inetAuthorizedServices=jabber)(uid=%u))
LDAPMethod rebind
</Plugin>
</VHost>
LDAPURI , LDAPBaseDN, and LDAPFilter are required
Everything else is optional.
The Only LDAPMethod supported at the moment is rebind which performs a bind as LDAPBindDN
or does anonymous bind, then searches for the user using LDAPFilter and then will rebind
as the found DN to verify the password.
LDAPFilter is an LDAP filter with a %u that will be substituted with the incoming userid
