Background:
I tried to upgrade our existing server using classicupgrade previously
working before with the previous version but because it was pending in a
couple of months as working with other projects.
Currently using with Samba 4.8.3 in Fedora 28, I don't know if it relates
to the previous version (4.7.x, which I used before) as I upgrade the
distro. I tried to delete the said account, then another account or machine
will appear with the same error up to 10 tries, I stop as kept appearing.

As Fedora 28 don't have samba 4.7.x version, will try to recreate the
server on a separate machine if this will resolve the issue.

Thanks.

Samba 4.8.3 is fine, but Fedora packaged Ldb 1.4.0 which breaks Samba.

ldb 1.4.1 will prevent this from happening at build time, but in the
meantime we have an unfortunate situation. 

Sorry,

No worries and thank you Andrew, for very informative feedback. At least I
know where I will be going.
