+urpm::ldap - routines to handle configuration with ldap
+
+=head1 SYNOPSIS
+
+=head1 DESCRIPTION
+
+=over
+
+=item write_ldap_cache($urpm,$medium)
+
+Write the value fetched from ldap, in case of failure of server
+This should not be used to reduce the load of ldap server, as
+fetching is still needed, and therefore, caching is useless if server is up
+
+=item check_ldap_medium($medium)
+
+Check if the ldap medium has all needed attributes.
+
+=item read_ldap_cache($urpm,%options)
+
+Read the cache created by the function write_ldap_cache.
+should be called if the ldap server do not respond ( upgrade, network problem,
+mobile user, etc ).
+
+=item clean_ldap_cache($urpm)
+
+Clean the ldap cache, remove all file in the directory.
+
