Dear all,
I have a situation where the Samba file server is the ADS domain member
of DomA, and the DomA is trusting another domain DomB.
Currently the Samba version I am using is 3.0.34 under Solaris 10 Update
7 with Sun Cluster 3.2 HA solution. I understand that the "trusted
domains" feature on this release is breaking, thus I cannot make it
works, and the path to upgrade to 3.2.2 is also not possible since it is
not supported by Sun Cluster agent.
Therefore I need to have a mechanism to trap the user from DomB, to be
"bad user", and allowing it to access as "guest" user. The problem I
have now, when the user from DomB is accessing the share, he/she is
always presented with the Windows password pop up, which is difficult
since we want it to be unattended or at least silently login behind the
application. Only after the user entering bogus username/password, then
he can access the share as guest user.
Basically if the authentication result is NT_STATUS_LOGON_FAILURE, the
dekstop will keep asking with pop up screen. Only when the result is
NT_STATUS_NO_SUCH_USER, it is directed to "guest" account.
What I want is that both authentication failure is mapped to "guest"
account, and supressing Windows login pop up.
Many thanks in advance,
Dedhi
