[Fedora-directory-users] Advantages of using FDS vs OpenLDAP?

[Bryan]

This question is probably completely obvious to those more versed in  
LDAP, which I am not.  And since I couldn't find an answer to this in  
the Wiki, I thought that it didn't hurt to ask.

So what are the advantages of using a "specialized" LDAP server,  
whether Fedora/Red Hat Directory Server, Apache Directory, Open  
Directory, etc., versus using just OpenLDAP?  Increased  
functionality?  Heightened and more security measures?
