[Samba] existing users can't conenct anymore after upgrade

[Peter Panholzer]

Hello list,

i have updated the fedora core 5 samba package yesterday. since then the 
existing users can not access the shares anymore, but new created users 
can. the log says "User <olduser> not in 'valid users'", but the old 
users are of course still there side by side with the new user. the 
update was from 3.0.14a to 3.0.23. i am using the 64bit package and 
selinux is disabled. deleting the olduser and recreate them doesn't 
help. deleting and recreating the systemaccount of the user doesn't help 
either.

seems to be the same problem as

any ideas?

thanks ...
