Changing name of windows computer, casues error in ldap

[talleyrand]

to standardize the computer names we were gonig to rename some computers that did nto comply.

The system was migrated from a 2008 win server and appears to have been running fine for months.
No problem adding new computers/ devices /users etc.

after rename we got errors thrown.
You can see at the top the rename. then some error about “MicrosoftDNS”.

Any solution or ideas as to what might be wrong ?

Still seeing it even after all the updates since Feb 2022

I worked my way thru:

HowTo: Migrate Samba 4 DNS data from the legacy to the default partition

HowTo: Migrate Samba 4 DNS data from the legacy to the default partition Please take into account that during the migration DNS is not fully available Step 1: Check if you have legacy DNS Zones: root@ucs:~# univention-s4search -b CN=MicrosoftDNS,CN=System,$(ucr get samba4/ldap/base) --cross-ncs |grep dn: |grep -vi root dn: DC=_msdcs,DC=multi.ucs,CN=MicrosoftDNS,CN=System,DC=multi,DC=ucs [...] → Migration is necessary There should NOT be anything below the CN=MicrosoftDNS,CN=System contain…

i get the following:
univention-s4search -b CN=MicrosoftDNS,CN=System,$(ucr get samba4/ldap/base) --cross-ncs |grep dn: |grep -vi root
dn: CN=MicrosoftDNS,CN=System,DC=zx01,DC=org,DC=mydomain,DC=com

(which indicates it is ok)
BUT!!!

ucr get connector/s4/mapping/dns/position
legacy

could it be all my errors are caused because the s4 connector is still on “legacy”?

and should i progress to : STEP 3 ?
