Hi,
attached are three patches related to
https://fedorahosted.org/sssd/ticket/2418
The first one simply adds the Windows Server 2012 R2 functional level.
The second falls back to the oldest supported Windows Server in case we
can't convert the the functional level but there is one in the rootDSE.
And finally the last patch relaxes the requirement for tokenGroups.
According to MSFT documentation, tokenGroups is available since Windows
2000, but the oldest release we have around is 2003, so I only
downgraded the requirement to 2003.
