Comment 22 for bug 1574653

Okay, I figured out that the problem with the autodiscover is that it checks whether a password is needed (which is realized by polling /usr/bin/ntlm_auth and if it returns YR, then it's considered as it has some credentials), thus since the changed behaviour of the /usr/bin/ntlm_auth this "without password" detection "fails" and reports that the password is not needed, thus the autodiscovery fails with 401, due to no password. A similar reason might be for the addressbook and other parts.
