[vlendec at samba.org]

Author: vlendec

New Revision: 25688

WebSVN: http://websvn.samba.org/cgi-bin/viewcvs.cgi?view=rev&root=samba&rev=25688

Log:
Add a simple test for a samba3 regression

When trying an reqchal/auth2 for an unknown workstation account, we have
to return NT_STATUS_NO_TRUST_SAM_ACCOUNT to the auth2. v3-2-test right
now returns NT_STATUS_ACCESS_DENIED, which seems to prevent XP from
joining a Samba3 PDC.
