From the wiretrace we can see that the server +returns different UIDs as response to NTLMSSP_NEGOTIATE and NTLMSSP_AUTH +phases. + +With changes in the authentication code, we no longer set the +cifs_sess->Suid returned in response to the NTLM_AUTH phase and continue +to use the UID sent in response to the NTLMSSP_NEGOTIATE phase.
