# wbinfo -V
Version 4.6.0pre1-GIT-f479b1b

# wbinfo -a DOTROLL+buz.richard%<password>
plaintext password authentication succeeded
challenge/response password authentication failed
wbcAuthenticateUserEx(DOTROLL+buz.richard): error code was
NT_STATUS_WRONG_PASSWORD (0xc000006a)
error message was: Wrong Password
