MSN Transport not appearing

I have two users…

If I use the admin interface and add the MSN transport for the user… all works fine. He sees the MSN transport in Spark, and his MSN buddies.

The other user registers for MSN via Spark… here the admin interface picks up the successful registration, but the MSN transport is not visible in the Spark client. I’ve had him reboot, I’ve restarted openfire, but nothing seems to work.

Can anyone help?

Thanks,

John
