And Thanks in advance for the assistance.
Trying to probe a cifs share on a cmode simulator. As I understand it a cifs share with acl Everyone FULL should suffice.
Win XP seems to net use fine with ntlm or v2 auth to the DC in the secd.log.
Trying to do the same when probe from my application (F5 ARX), filer keeps returning STATUS_UNSUCCESSFUL.
From the looks of secd.log looks like it fails when attempting to call doAuthWithDC as pkt capture shows that a connection was not made to the DC.
Anyone have an idea as to why or what this Unexpected State is below?

I remember seeing something about ARX not support SMB 2 yet (but that may have been added since then) but that may be related.
The -smb2-enabled option is enabled by default... does it work if you turn off smb2?
vserver cifs options modify -vserver vsname -smb2-enabled false

You are correct ARX does no support SMB2 as of yet.
The pkt trace indicates that XP is using SMB1 and ARX is using SMB1 as well. I tryed to turn SMB2 off as you suggested. The end result was the same. Net use via XP is fine. ARX can't probe. Crazy.
Any other thoughts?

The 8.1.1 relnotes show support for SMB 2.1 which seems to be the major cifs change...but the client is using SMB1..unless a change or interaction issue with ARX.. Is there an F5 case open?

Yes, I have an internal PD bug open. This is an interop issue between the filer and ARX. Working with Engineer's in India with little response. No fault of there own considering the time difference and the fact that XP, 7 clients do work.
I can probe the DC from the filer.

Most use pcuser but we have had root set in some installs...as long as there is a mapping that is what is needed. You can modify the default to pcuser and make sure the unixuser exists for pcuser but doesn't sound like the cause.

Thanks Scott, I'll try. I assumed that would not work becuase of UID / GID being 65534 65534. I think root squash. Could be way off here.
Does cifs options default user = pcuser sufficent enough for mapping win user to unix user?
