fantastic - It works !! 
I'ts like administering a windows-workstation - If you have a problem, wait
some couple of time and if you are lucky it went away by itself ;-)  ... and
if not - do a new install - but thats a other story ;-)

Thnaks for the explanation - seems clear to me. I read about 400 Pages
AFS-Dokumentation today - there was nothing told about that issue. 

Afs is really cool - but for a noob not the easiest to understand -
particularly cause most of the dokumentation is in english - and my english
issn't the best as you can probably read ;-)

Thanks for the very,very fast response !!

maybe wrong place here, but I need to setup a afs->Samba gateway as our
workstations are all running windows and we have a samba server in our
is it a goot way I'm going or would you prefer something like "kstart" or so
for the samba acess to afs !?
we have a ADS where all our users are authenticating against from their
windows side - and I dont wanne to create a pts-entry for every user we
have. I would do the ACL over samba - so I think I can use that IP-Based ACL
- or not?
Any better suggestions or links to a "easy" How-To - maybe in German ;-))) ?
