Subject: [PATCH 192/192] libwbclient: Change return code for
 wbcAuthenticateUserEx

Samba-4.6 change behaviour of few functions
New version of code make sure session info for user is stored in cache.
It is a performance optimisation to prevent contacting KDC for each
session. More details in samba bug
https://bugzilla.samba.org/show_bug.cgi?id=11259

Old return code WBC_SSSD_NOT_IMPLEMENTED was translated
to NT_STATUS_LOGON_FAILURE which caused many failures.
