I understand. The key issue is that to support the wildcards we
changed the way we use the database, the SCOPE_ONELEVEL index (compared
with SCOPE_BASE used exclusively in the past) over 7000 possible

Samba 4.7.0 replication issue: failed get spanning tree edges
Did you check that these groups were actually consistent before you
upgraded (have you got a backup to look at the old groups)? The
consistency checking definitely got stricter in 4.7, but there may still
be a bug here.

BIND9.8 DLZ performance issue
Hello,
I'm running Samba 4.5.0 and bind-9.8.2-0.47.rc1.el6_8.1. One DC of
four, the PDC, is magnitudes slower running
/usr/local/samba/sbin/samba_dnsupdate --verbose --all-names. When that
is running on that DC it seems to block any queries. The load average
is usually under 0.5. The DC was unsafely halted, which could have
corrupted something. I ran a dbcheck with samba-tool and it

winbind inconsistent group membership
I have 4 Samba 4.7.0 DCs. I have 3 clients using samba-winbind.x86_64
0:4.6.2-11.el7_4 with an identical configuration, which produce
inconsistent user group membership for multiple users. I've tried using
all 4 DCs explicitly (e.g., realm = dc01.mediture.dom), net cache flush
and restarting winbind. I've also tested cloning a user and setting up
the user as identical as possible:

BIND9.8 DLZ performance issue
I'm hoping the issue is just load balancing, but I'm not sure. I can't

I ran this script on all Linux nodes to balance the traffic.

Replications errors on 4.5.0 (WERR_BADFILE)
The errors went away, but replication still isn't working properly.
There are objects missing on all DCs, but it isn't consistent at all.

I believe the problem is a lack of outbound replication for non PDC
emulator DCs. You'll notice isn't even trying because last successful

DC seems fine.
