I did this for a project at my old company. We were using ApacheDS as a LDAP server, but we were doing a lot of updating to the datastore, and DS kept having issues with corruption. But our use case was really limited, so I wrote a server process that talked LDAP, but it was essentially hard coded to support the 4 or 5 queries that we actually did. Then it was backed by our core Postgres backend. The ASN parser was the trick of it to be sure. For whatever reason, I had a lingering bug in it that I could never track down. Some kind of heisenbug that I was never able to duplicate, and even spamming the logs with tons of debug info, I could never get a handle on it. It wasn't fatal, but it was annoying. Been so long, I don't recall the details. ASN is tricky, but it's not that hard. But, in the end, it worked for our use case.
