[dev] bad typo in lib/Auth/ldap.php

[Gabe Schine]

hey... to someone who can make this change (i'm not sure how to actually 
submit code work...), in horde/lib/Auth/ldap.php, the documentation at 
the top of the file states that the parameters should provide a "passwd" 
key, when in fact the code is looking for "password". one of the two 
should be changed, IMHO, since it took me a while to figure this one out.
thanks

ps. this is in the HEAD branch
