thanks for your explanation, you're right of course and i already 
suspected there wouldn't be a way, because it actually doesn't make much 
sense. in my case it was only a question of convenience, because the 
ldap server used isn't designed for a samba backend and servers mainly 
other purposes (although ldapsam does work). it's rather costly to get 
users in there, but i'll go this way
