libwbclient's wbcAuthenticateUserEx call requests the INFO3 struct in text form. Samba4 winbind currently doesn't handle this.
How do we need to handle this? Is it needed to fix libwbclient or Samba4?
libwbclient needs this to fill out the info3 struct, as it has no way to decode an NDR-encoded info3 blob. This currently causes the failure in wbinfo -a against the S4 winbind.
Should be fixed by 68e1991c6cfd34a6852c5be24259285c6214ea3c.
