findUserDN function is available in /usr/share/pear/Horde/Ldap.php

but, findUserDN is not correctly setting the parameters passed.

below is the output.

Nov 21 2013 14:53:57 DEBUG: HORDE [passwd] Failure in changing password for
LDAP Server: Bad search filter
Parameters:
Base: dc=xxx
Filter: (&(objectclass=)(=asa)

In the above statements, dc=xxx is correct.
the Filter should have populated as

(mailacceptinggeneralid=asa)

I have set uid=> mailacceptinggeneraid
and filter => ''

in backends.local.php of passwd for LDAP driver.
