Hi Juergen!

The same is true for this product on other platforms (IBM Tivoli 
Directory Server is available for Solaris, Windows, ...). A major 
advantage is that the LDAP server inherits some nice DB2 properties 
(high availabilty features, distribution) especially on AIX.

ApacheDS architecture is quite flexible and allows you to extend the 
server with your own partition implementations.

We had several questions about a JDBC or Derby partition the last 
months. From my point of view it would be nice to have a JDBC partition 
(reasonable/performant or not), for instance as an example on how to 
write your own partition.

Unfortunately, our resources are limited (all volunteers). Currently 
ather things have a higher priority. But contributions are always 
appreciated. Perhaps you would like to share your experiences with 
ApacheDS on z/OS, as well.
