My fault, I have only been looking at the ldap part of apache 
directory... I defininitly shall try the kerberos/dns/dhcp part of 
ApacheDS. Currently I'm using heimdal, bind and isc dhcp server on ldap 
backend (openldap), and looking for better solution, that's why I'm 
following this list. I didn't realized I could already get all of it 
bundled in ApacheDS! I'll try to accomodate for a few hours to roll out 
a test bench.

Sorry I think I misrepresented my point. I don't claim that ActiveDS is 
a good, bad or better LDAP server. I just wanted to point out that 
ActiveDS is not just an ldap server. The fact that it is much more than 
an ldap server makes it one of the most difficult part of proprietary 
stuff to get out of a IT infrastructure... What a pain !

If everything was too easy, there would'nt be any more fun geeking around!
