[Samba] annoying authentication failure problem: sambatest[ho stname]

[MCCALL,DON (HP-USA,ex1)]

Hi Toni,
This error is the result of a test that samba does in the module
"server_validate", (in password.c) to check the password server for a bug
where NT 4 (some versions) would not correctly set the guest bit.
There is currently no smb.conf parameter to allow you to control this
behavior, so to change it , you would need to actually hack the password.c
module to disable it.
Not difficult, but you would leave yourself open to a security hole, if the
password server you are using (esp. if you have password server=* set in
smb.conf) gets one of the versions of NT that has the bug after you have
removed this protection.
Most of us don't have control over our NT domains, so we can't guarantee
this won't happen - thus our 'paranoia' in the code we CAN control ;->.
Hope this helps,
Don

Hello,

I have a little problem which appeared when I installed first 2.2
generation sambaserver on linux and same effect when updated 2.0.3 to
2.2.2 on hp-ux.
The actual problem is that my security servers log (NT4 server) get's
failure message every time someone connects to samba share which is
quite log and it get's frustrating to search real information from logs
when this failure message fills log. Fortunately the service works fine
and this problem is transparent to a user but bothers administration...
If someone would have a tip to remove this feature it will be highly
appreciated.

about authentication settings

security=server
password server=[NT4 servername] which is also pdc

the error message from nt eventviewer security log:
