Following this blog link, adjusting appropriately for environment (bind user admin, password, appropriate domain info, etc.), otherwise everything exactly as outlined:
Getting: Success! Sync of users finished successfully. 0 imported users, 0 updated users
No users ever imported, even though I can communicate with the test connection and test authentication buttons, ldap is unencrypted for testing purposed, ldap://server.example.com:389. SSO server is joined to ipa realm, I can query any of the ldap servers w/ ipa commands as well as ldapsearch commands. Any input would be appreciated!
