Replace Active Directory with OpenLDAP and Others

Hi,

I was wondering if there is an uptodate guide/tutorial/howto to replace Active Directory. I found http://www.bayour.com/LDAPv3-HOWTO.html but that was last updated in 2005.

Also I could not find any references to people actually having replaced Active Directory. In my head it should be possible, but replacing MS products does not always make sense in practice. ;-)

I have not yet had the time to fully work through the howto. but either way I will give it a try (well a couple probably)

Has anyone have any experience or advice with this?

Thanks in advance

Regards,

Serge Fonville
