+
+DJabberd::Authen::LDAP - An LDAP authentication module for DJabberd
+
+=head1 VERSION
+
+Version 0.01
+=cut
+
+our $VERSION = '0.01';
+
+=head1 SYNOPSIS
+
+
+
+ [...]
+
+
+ LDAPURI ldap://localhost/
+ LDAPBindDN cn=reader
+ LDAPBindPW pass
+ LDAPBaseDN ou=people
+ LDAPFilter (&(inetAuthorizedServices=jabber)(uid=%u))
+ LDAPMethod rebind
+
+
+
+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
