[Samba] user authentification error with new samba version

[Goetz Hatop]

from samba 3.0.9 to 3.0.13

I can not access my shares from a NT4 box as usual
before upgrading.

I can access samba shares from linux via
   mount //server/testuser /mnt -o username=testuser,password=testpass
as before.

Even the newest version (3.0.14a) from samba.org doesnt't help.

What has happened to samba ??? Any hints ??

Thanks for your thoughts,
 Götz.
