The web interface provided by 389-admin doesn't do very much.
You might
want to use 389-dsgw.
Does anybody know if the DSGW interface is available for CentOS Directory Server?
The RHDS docs mention it, but the only file that appears on the server were I
installed CDS is: admserv_dsgw.html. No conf files or anything else. I had
installed the Webmin OpenLDAP client for managing users, but although it mostly
works, there are some compatibility issues and shortcomings.
