test_integration/test_backup_and_restore.py:1059: AssertionError

The test scenario is the following:
- make replicas[0] a trust controller
- make master a trust agent
- query server role on the master, should show master as trust agent.

The test can randomly fail if the query for the server role is executed before the replication had time to replicate the changes on cn=adtrust agents,cn=sysaccounts,cn=etc,dc=ipa,dc=test, as the server role is read using this entry.
