I discovered, for an exemple, if you have a user group with 3 members (Alan,
Baker, Clive), before 3.0.23c this line worked fine:
 
valid users = @user
 
But with 3.0.23c it doesn't work anymore. You have to replace the line like
this:
 
valid users = Alan, Baker, Clive
 
I mean, replace the @groupname with the complet userlist of the group
separated by commas.
 
It?s a quick solution, but some groups are large and it?s kind a hard to do
that with all of them.
 
Anyway, I found this other discussion
(http://www.mail-archive.com/samba@lists.samba.org/msg78460.html), where
people say something about a patch (which, unfortunatelly, I have no idea
how to use or apply)...
 
 
I ?d appreciate any help or comments.
 
Thanks!
