I am running samba 3.0.2a and am trying to validate a user account using wbinfo -a USERNAME%PASSWORD against an NT4 Server. I get the following: plaintext password authentication failed error code was NT_STATUS_NO_SUCH_USER (0xc0000064) error messsage was: No such user Could not authenticate user USERNAME%PASSWORD with plaintext password challenge/response password authentication succeeded It appears that first a clear text password is tried which fails and then an encrypted attempt is successful. The probem is that wbinfo returns a non zero exit status which indicates a failure. If I use and incorrect password I get: plaintext password authentication failed error code was NT_STATUS_NO_SUCH_USER (0xc0000064) error messsage was: No such user Could not authenticate user USERNAME%BADPASSWORD with plaintext password challenge/response password authentication failed error code was NT_STATUS_WRONG_PASSWORD (0xc000006a) error messsage was: Wrong Password Could not authenticate user USERNAME with challenge/response So it appears that essentially everything is working but that because the first clear text attempt fails wbinfo returns a non zero status even though a subsequent attempt was successful. How can I stop the attempt using a clear text password? Mike Sullivan
