[Samba] accidentally upgraded DC to 4.17.3 ... didn't work

[Stefan G. Weichinger]

I think I solved it.

Completely uninstalled samba-related packages and dependent libraries 
and stuff and installed fresh from bullseye-backports.

did:

apt-get install  -t bullseye-backports  acl attr samba 
samba-dsdb-modules samba-vfs-modules winbind libpam-winbind 
libnss-winbind krb5-config krb5-user dnsutils

Seems to work now.
phew

side note:

# host -t A  adc2.arbeitsgruppe.my.tld

host: error while loading shared libraries: libdns-9.16.33-Debian.so: 
cannot open shared object file: No such file or directory

Can't find that file on

https://packages.debian.org/

I now also upgraded one domain member server. Same picture.

I had to remove "samba-common  samba-common-bin  samba-libs" extra, and 
run "autoremove" ... that removed

"libnss-winbind libpam-winbind libsmbclient python3-samba samba 
samba-common samba-common-bin samba-dsdb-modules samba-libs 
samba-vfs-modules smbclient winbind"

After that installing again from backports. -> works so far

*phew*

I will keep it like this for today and wait for feedback.

The other DC and the second domain member (=fileserver) tomorrow.
