[Samba] Users suddenly have no access

[tom]

Hello,

I have a big Problem here:

samba 3.5.6, LDAP, 200+ Users.

Some users can't logon to a share anymore, where they still could login last week.

net rpc user info userxyz
gives the groups
group1
...
group8

but not the group group9


but net rpc group members group9 gives me
.......
domain\userxyz
.......

So, the user is a member of the group9, but his membership is not listet in net rpc user info.
So it could explain while access is denied.

But what's the reason?

Can anyone help ?
