We have a customer that is asking for an integration with a 3. party contact book service for phones to use like an external LDAP Server. The contact book service is able to talk SQL or REST (not LDAP).

We are thinking of building a more general LDAP proxy maybe as an App for the App Platform v13 but I'm not sure how to approach this:

- Should I build and integrate everything using the Innovaphone Apps SDK and probably also use some 3. party library. This means that App Platform (Linux) itself should be able to listen on LDAP port 389/636 and forward request to some SQL or REST service?
- Should I build the LDAP proxy server as an 3. party service. I'm thinking of Java. Would I be able to install this on the App Platform Linux server - maybe in a Docker or just a Java jar daemon?
- Should I build the LDAP proxy server as an 3. party service and just run it on another server?
- Should I just build a v13 App that is able to manage such an LDAP proxy server?

I would like to discuss this and get some input from you guys?

Cheers,
Martin
