This document discusses bringing OpenLDAP configurations into Apache Directory Studio. It provides an overview of configuring OpenLDAP using either the traditional slapd.conf file or the newer cn=config backend in LDAP. It then introduces the OpenLDAP configuration plugin for Apache Directory Studio, which allows configuring OpenLDAP in a graphical user interface without needing to directly edit configuration files. This plugin aims to simplify OpenLDAP administration and prevent configuration errors.

8. Why cn=config ?
Configuration in LDAP
Can be replicated
Allows dynamic configuration
Protects against misconfigurations

9. But...
People keep using vi/Emacs
More complex than slapd.conf
You have to use
ldapadd/ldapmodify/ldapdelete
9

10. But...
« It is of course possible for a careful, clueful
admin to edit the files by hand without breaking
anything. »
« But let's face it, the majority of people out
there, and particularly the people having
problems that drive them to post on this mailing
list, are neither careful enough nor clueful
enough to qualify for these activities. »

11. Let's use Studio !

12. OpenLDAP configuration plugin
Don't have to lecture people who
use text editors
Config for dummies (almost)
Many controls done by the plugin
« smart » editors

13. Backend configuration

14. HDB configuration

15. Replication configuration

16. Options configuration

17. What's next ?
Polish the editors
Make it work with slapd.conf
Add the missing elements
Manage versions
Release it !!!
