[Samba] Change/modify on GPO doesn't apply all necessary ACL

[Guilherme Boing]

Same thing happens here.
sysvolcheck was just fine without any GPOs created.

Now, I've just tried to create a GPO, didn't add any configuration/rule to
it, and sysvolcheck already returns the same error:

ldb_wrap open of idmap.ldb
ERROR(<class 'samba.provision.ProvisioningError'>): uncaught exception -

I have two DCs, and the other DC was also returning no errors on
sysvolcheck, however after creating a GPO it now returns "No such file or
directory"
ldb_wrap open of idmap.ldb
ERROR(<type 'exceptions.TypeError'>): uncaught exception - (2, 'No such
file or directory')

Running self compiled Samba 4.2.3.
