If ubilogin-directory fails to start, start from the command line using the start.sh command in order to view the detailed error messages.
"Base DN "entryTtl,entryExpireTimestamp" is not within the database naming context" means that the searchbase or binddn values in dn=*.conf are incorrect. Check and correct.
If an error regarding bind address or port "already in use" persists despite stopping and restarting UbiloginDirectory, use netstat to check which process is listening to port 389 and terminate the process.
If the Ubilogin-server fails to start or replication does work as expected, it is possible to run the slapd in debug mode using the -d -1 arguments. Copy the openldap/start.sh script, edit the script to include the -d -1 arguments and start interactively from the command line.
