APROL R4.4-01 P4: AprolChangeHost and LDAP

I have used AprolChangeHost several times in the past without any issues. However, with R4.4-01 P4, I am running into a problem related to LDAP. I have git a single system (ERO = engin, runtime operator on one server)

I executed:

AprolChangeHost -user me -oldhost old.host.dmn -newhost new.host.dmn

Afterwards, I applied the generated changes using AprolConfig.

When I start the CAE Manager, I receive the alert:

“Connection to LDAP could not be established.”

I also tried restoring the LDAP configuration, but this did not resolve the issue.

Fortunately, I created a VM recovery snapshot before performing the host change, so I can revert to that state and no data has been lost.

Has anyone experienced a similar issue or can suggest what else I should check after running AprolChangeHost?

Any idea Christian Peham ?
I have never used APROL so far.
Thanks
