Hi Michael,

I just want to remark that LDAP is a protocol not a server by nature. There 
are ways of authentication against a relational database by the LDAP!!!!

LDAP server have disadvantages comparing relational databases:

1.) The ID inside an LDAP server is the "path". Relations would be lost, if 
you move entries.

2.) In relational databases you can assign a user to multiple groups. In an 
LDAP server every user is part of one group. Multiple relations are badly 
supported because of the hierarchical nature of LDAP servers.

Unfortunatly some software like email clients only know the LDAProtocol for 
connections. But again: I think it the most flexible solution to access 
relational databases by LDAP instead of setting up LDAP servers.
