NT bug

[Cole, Timothy D.]

Noticed this in smbd/password.c:

  /*
   * Attempt a session setup with a totally incorrect password.
   * If this succeeds with the guest bit *NOT* set then the password
   * server is broken and is not correctly setting the guest bit. We
   * need to detect this as some versions of NT4.x are broken. JRA.
   */

What versions/service packs of NT 4 are affected, and under what
circumstances does this bug manifest itself?
