Openldap error on upgrade to Cartbonio 25.6.0

Hello Everyone. 

I'm trying to upgrade my Carbonio CE 25.3.1 to CE 25.6.0 and it's resulting openldap error.

My server is installed with Rocky Linux 9.
First I've upgraded OS using

# dnf upgrade --disablerepo=zexrras

At this point I got some problems like "Permission denied: token with AccessorID ... lacks permission ..."

I've fixed running:

# carbonio-message-broker setup

Then when running:

# dnf upgrade (including zextras repository) result in openldap error:
