[Samba] Weird Problem after Upgrade 3.0.7

[Peter Huetmannsberger]

Hi!

Well ,the upgrade to 3.0.7 on my Fedora Core 1 Box did not change the 
problem I described a few days ago. 

Samba 3.0.2 works fine with the NT4 Box I use to connect to with winbind. 
All the users are found and the permissions on my samba shares I offer the 
NT4 Box are the way I want them to be (well almost, says the windows 
admin). 

However after the upgrade it looks ok. BUT: 

getent passwd gets me: 

CENTRUM+Dummy:*:2011:2000:Dummy-User:/home/CENTRUM/Dummy:/bin/false

However if I want to change ownership on a file, as in:

[root at linux sambatest]# chown CENTRUM+gillian testfile
chown: `CENTRUM+gillian': invalid user


similarily with setfacl 

[root at linux sambatest]# setfacl -m u:CENTRUM+Dummy:rw- testfile
setfacl: Option -m: Invalid argument near character 3


After a downgrade to 3.0.2 on my FC1 box everything is fine again. 

Any idea what could be wrong? It's the same phenomenon as with Samba 3.0.6

Many thanks in advance,
