The use (or non-use) of DSML…

SuperPat aka Pat Patterson, one of our expert on Sun Java System Access Manager,  is asking if anyone uses DSML ?
After co-authoring the DSMLv2 specifications with Microsoft, we implemented it in the Sun Java System Directory Server 5.2 nearly 2 years ago, provided some client tools in the Directory Server Resource Kit,  and still we haven’t heard of any customer’s deployment using DSML.
I did get some reports from the field of some evaluation of DSMLv2, got
a few questions with regards to security and authentication, a couple
of queries on the performances… but still I have not heard from any
use in production.
And the last time I discussed about DSML with a friend who works for Novell, he basically said the same thing.

Still DSML is coming back in conversations some time to time, like
today as DSML was mentioned on the OpenLDAP mailing list with a proposed implementation of the client and the server side.

So, I’ll re-iterate Pat’s question: Is anyone using DSML ?

    Hi Ludo,
    I know of one customer using DSML in production 😛

    I’m currently developing a project using DSML as an access layer to OpenLDAP.
    We have some authentication problems ;-D

    Yes I am actually. My current thinking on metadirectory involves passing LDAP events as dsml inside xmpp pubsub messages to multiple subscribers.

    Hi Ludo:
    In fact, we have one client that is actively using it, and another is evaluating it. My observation is that DSML will continue to gain traction as companies increase implementation of “Identity as a Service.”
    Best regards,

    Surprisingly the last comment about DSML was more than 18 months ago. I am not sure DSML will continue to gain traction. But you may want to read Trey’s post on Atom, APP and OpenDS

    Directory Server 6.3…. DSML enabled
    Directory Proxy enabled for Directory Instances
    How do I load balance DSML Requests ? I don’t see an opetion in the Directory Proxy.

    Hi Jay,
    Directory Proxy Server is an LDAP proxy.
    DSMLv2 is a protocol using SOAP and HTTP. There are many HTTP proxy servers that are capable of load balancing DSML requests.
