Issue

I was trying to help on a new test for test_integration/test_ipa_ipa_migration.py::TestIPAMigrationProdMode and consistently got a failure in cls.replicas[0] trying to read cls.master with "Failed to bind to remote server: cannot connect to 'ldap://ipa.example.test': Connection refused"

I manually added master to the replica hosts file and that resolved the issue.

I created three new VMs: one for the controller, one for the master and one for the other master (replica[0]).

I setup a pretty standard config file declaring the two servers.

I disabled client in the MigrationTest class because I didn't need it.

I run the tests with:
PYTHONPATH=. IPATEST_YAML_CONFIG=/root/freeipa/ipatests/test-config.yaml ipatests/ipa-run-tests test_integration/test_ipa_ipa_migration.py::TestIPAMigrationProdMode

I don't understand how this works in PR-CI with the replica not knowing how to connect to the master without some pointer in DNS or /etc/hosts, but it obviously works somehow.
