[Samba] Active Directory Domain Corruption.

[Zombie Ryushu]

I have unable to process any Domain Logins of any type on OpenSuse Leap 
15.3. I get an invalid SID error.
This has been isolated to just one of my Domain Controllers. 
Unfortunately, its my Primary Domain Controller.

Basically normal Samba and Domain AD Logins fail with

NT_STATUS_INVALID_SID

A Bug report has been opened at:

https://bugzilla.samba.org/show_bug.cgi?id=15079

Kerberos KDC and LDAP functionality still works, but not much else does. I believe that some sort of corruption has entered the database.
My other two DCs are unaffected. Please review the errors in the bug reports and advise.
