Hello, everyone.

1. @cyril, Your link is not a website about the “step by step” tutorial. Can you recommend some websites like this?
2. @becot, your book. It was 7 years ago. Do you think it is still ok now?
3. Today I learned about a software called FreeIPA. but FreeIPA uses 389 Directory Server that is a very different project compared to OpenLDAP. So do you know what software that uses OpenLDAP can replace FreeIPA?
