Ok, I have installed the Fedora Directory Server. Installation is quite strait-forward, configuration is done through simple wizard and is very easy.
Next step is Management Console. It is a java-based (I guess so) interface with lots and lots of things inside that I do not know :( :)
Anyway – I decided to study all of it so I am currently downloading tons of PDF files from redhat and I gonna read all of them in the NEAREST future since I really believe that this is something great and that I have (or no – MUST) no it :)
