Greetings, All!
I've added a new DC to the working AD, transferred FSMO roles (checked, all
7
are ok') and (supposedly) correctly demoted the old DC.
SchemaMasterRole owner: CN=NTDS
Settings,CN=DC2,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CNInfrastructureMasterRole
owner: CN=NTDS Settings,CN=DC2,CN=Servers,CN=Default-First-Site-Name,CN=S
RidAllocationMasterRole owner: CN=NTDS
Settings,CN=DC2,CN=Servers,CN=Default-First-Site-Name,CN=Si
PdcEmulationMasterRole owner: CN=NTDS
Settings,CN=DC2,CN=Servers,CN=Default-First-Site-Name,CN=Sit
DomainNamingMasterRole owner: CN=NTDS
Settings,CN=DC2,CN=Servers,CN=Default-First-Site-Name,CN=Sit
DomainDnsZonesMasterRole owner: CN=NTDS
Settings,CN=DC2,CN=Servers,CN=Default-First-Site-Name,CN=S
ForestDnsZonesMasterRole owner: CN=NTDS
Settings,CN=DC2,CN=Servers,CN=Default-First-Site-Name,CN=S
Now, I'm unable to connect to the domain using RSAT - the error is "RPC
server
unavailable".
Tried to forecefully remove old DC from the new one, just to be sure. It did
some additional cleanup, judging by the wall of debug messages, but that did
not help in the slightest.
Googled a bug https://bugzilla.samba.org/show_bug.cgi?id=12534 and manually
removed the last DNS record.
Now the DNS check reporting only new DC, but it is still not working like it
should.
So far, I've made these checks:
I can impersonate domain users and login with SSH using domain users on
domain members, even new logins with homedir creation, but?
Domain users/groups listing works partially.
One member:
groups: cannot find name for group ID 10008
groups: cannot find name for group ID 10009
groups: cannot find name for group ID 10010
# getent group | grep -P "1\\d{4}"
domain sudoers:x:10006:
domain admins:x:10000:
domain users:x:10001:
cvs:x:10005:
Another member:
# getent group | grep -P "1\\d{4}"
domain computers:x:10003:
domain sudoers:x:10006:
domain admins:x:10000:
domain guests:x:10002:
cloud admins:x:10010:
domain users:x:10001:
remote users:x:10009:
cloud users:x:10008:
git admins:x:10007:
cvs:x:10005:
Even wbinfo lists groups/users incorrectly on different machines.

Domain authorization works? not.

Sorry, try again.

At the same time LDAP works like a charm and top-level tests pass
# net ads testjoin
Join is OK

But?
# wbinfo -t

DC smb.conf attached, if needed.
I have a full offline backup of both DC's prior to transfer and already
tried
to redo the process, but to the same effect.
So, what can I do now?
