An F720,  (6.0.1R3) exists in an NT "resource" domain that is trustING. The trustED
master domain (with all user account information) is called "dwkcb".
There is a One-way trust between domains ie. we don't trust the
resource domain. (Don't ask why its a long story.)

A cifs share is called "test_ntfs" with ntfs security style. From a Sun box
as walt a cd into it gets permission denied.

Here is an overview:
nas01> qtree
Volume   Tree     Style Oplocks
-------- -------- ----- --------
sys               unix  enabled
sys      jobs     unix  enabled
sys      projects unix  enabled
sys      scans    ntfs  enabled
sys      software unix  enabled
sys      test_mixed mixed enabled
sys      test_ntfs ntfs  enabled
sys      test_unix unix  enabled
 

Account "walt" exists identically in both the NT domain "dwkcb" and a
NIS domain. However here is the error we get (NetApp support has never seen
this):

nas01> wcc -u walt
Thu Nov 29 10:08:01 EST [rc:info]: Located account "DWKCB\walt" in domain "DWKCB".

Has anyone seen this or anything similar? We won't consider a two-way trust nor
can we change the domain of the filer.

Any thoughts appreciated.
