We are having trouble accessing a cifs share (with ntfs security style) from a Sun box.

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". Thu Nov 29 10:08:01 EST [rc:error]: SamrConnect2: Exception rpc_s_call_id_not_found caught. Error 0xc002001b mapping UNIX name walt nas01> Thu Nov 29 10:08:01 EST [rc:info]: Error c002001b looking up domain groups

nas01> wcc -s walt Thu Nov 29 10:08:07 EST [rc:error]: SamrConnect2: Exception rpc_s_call_id_not_found caught. Error 0xc002001b mapping SID S-1-5-21-234058047-1151164854-1844936127-1008 nas01> Thu Nov 29 10:08:07 EST [rc:info]: Error c002001b looking up domain groups

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.
