Middleware, or "glue", is a layer of software between the network and the applications. This software provides services such as identification, authentication, authorization, directories, and security.

I agree Frank, it should be a data tier like database.

Frank & James,
It's not totally clear to me that LDAP is a Middleware product. So, I asked my colleagues here at the Middleware department in this _huge_ company (quarter of million people) and they indeed support LDAP. I also think that conceptually, LDAP is much closer to the app server than the DB. It provides identification, authentication and authorization services very quickly. It is an integral part of the services the Middleware tier provides. In other words, its functionality is tied to the app server functionality.
Hi everyone, I think everybodies right! LDAP is one of those things that can have many interpretations. It is closely linked with the server, but also has a database which can be considered to be on the EIS tier.
Why not think of it as a pluggable security mechanism instead (i.e. a service)? similar to how DB2 works with JDBC?
You can choose between a variety of security and persistence mechanisms.
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
