"Logon Failure" when running executables on NAS

[Guest Lynn Henderson]

I have a Linux-based NAS running Samba with user-level password

protection (the same userid and password as Vista). I can browse files,

etc., but I am unable to run any executable files. UAC prompts me for

approval, but then give me a "Login failure: unknown username or bad

password" error. It must be a UAC issue because I have no problems when

I turn UAC off, but I'd like to leave it enabled if possible. Anyone

else experience this issue and have a solution? What exactly is Vista

sending as the username and password when elevating an application via

UAC? Maybe I could set up a dummy user on my NAS that reflects the user

and password Vista is sending.

 

Thanks.
