I checked the SuSE kernel from SuSE 9.3 which is a 2.6.11 (I'm always using SuSE kernels due to some patches in there that I need), and the problem goes away. Now also the first mount from the 2.6.8-server has ACLs. So it really looks like a client bug. Now I must hope that the SuSE team might fix this for the older kernels :-) Olaf/Andreas: If you want to take a look at this bug, let me know if I can provide some logs/debugging info etc. With the server running the 2.6.8 from 9.2, the bug occurs on the client side with 2.6.8 and the 2.6.5 from SLES9 up to SP2-RC, but not with 2.6.11.4-21.7 from 9.3. cu, Frank -- Dipl.-Inform.
