What were you trying to do that didn't work?

dsconf currently allows to create a new backend, when there is not enough named databases (at least 35)

What is the impact of this issue to you?

Please provide the package NVR for which the bug is seen:

389-ds-base-2.5.2-2.el9_5.x86_64

How reproducible is this bug?:

always

Steps to reproduce

Create a DS instance with MDB backend

Set max dbs to 50 and restart the server

dsconf localhost backend config set --mdb-max-dbs 50
dsctl localhost restart

Create a new backend

dsconf localhost backend create --suffix=dc=test --be-name=test --create-suffix --create-entries

Expected results

dsconf should check if enough named databases are available.

Actual results

dsconf localhost backend create --suffix=dc=test --be-name=test --create-suffix --create-entries
Error: -1 - Can't contact LDAP server - [] - add_ext_s((dn: dc=test
dc: test
description: dc=test
objectclass: top

,),{'serverctrls': None, 'clientctrls': None, 'escapehatch': 'i am sure'}) on instance localhost

Server stops and has the following errors in the logs:
