We have an AD domain (based on old Samba 4.1.9), and currently in LDAP
database we have some errors, which samba-tool dbcheck cannot fix.
for example:
-----------------------
samba-tool dbcheck --fix
(.... many similar errors ...)

Segmentation fault
-------------------------
If I join a newer samba (for example, 4.4.7) as a DC to our domain,
transfer roles and demote an older DC, is this error replicate to it?
I cannot figure how to fix it, and upgrade is needed anyway.
And second question about samba-tool dbcheck - where are a
manual/description for options?
In man samba-tool it very short:
https://www.samba.org/samba/docs/man/manpages/samba-tool.8.html
COMMANDS
dbcheck
Check the local AD database for errors.
delegation
......
But it has a many options, like:
samba-tool dbcheck --cross-ncs --fix --yes
samba-tool dbcheck --cross-ncs --reset-well-known-acls --fix
Or it has an option to run with individual tests.
What are meaming --cross-ncs, --reset-well-known-acls and other (where
is full list)?
