+Subject: [PATCH] auth: Fixed mech_winbind_ntlm by using mech_winbind_auth_initial()
+
+In changeset 9002 a new function named mech_winbind_auth_initial() was
+introduced, but only the mech_winbind_spnego module part was changed to finally
+use this function.
+The mech_winbind_ntlm module part was not properly adapted which leads to a non
+functioning NTLM authentication mechanism while using winbind, because it will
+never call the `ntlm_auth` helper.
+
+The simple fix is to replace mech_generic_auth_initial() with
+mech_winbind_auth_initial() as auth_initial "hook" when setting up the
+mech_winbind_ntlm module, like it is done in the mech_winbind_spnego module.
