r4946: Our notion the other_sids in the info3 SamLogon struct was

...hmmm... completely bogus. This does not affect us as a domain controller,
as we never set other_sids, but I have *no* idea how winbind got away with it.

Please review thoroughly, samba4 idl looks closer to reality here.

Test case: Member of w2k3 domain, authenticate as a user who is member of one
or more domain local groups. Easiest review with 'client schannel = no'.

Thanks,

Volker
