Most of configuraion is done with ldap attributes - some of them are
even configurable during runtime via ldapmodify.

It's all very well documented in either

https://access.redhat.com/documentation/en-us/red_hat_directory_server/10/

or

https://directory.fedoraproject.org/

Search the 389-users mailing list
https://lists.fedoraproject.org/archives/list/389-users@lists.fedoraproject.org/message/ZNZ2ADZKCXFHQKNUTHJ7IC57EGGLCFLJ/
for help.
