R6 - Applet- Corba- IIOP-Record Locking

We have a cluster environment with one ICM machine and two application servers (A and B). Server B is the admininstration server (master Lock server). We are trying to use Java applet to lock records when the user opens a document in edit mode. We have enabled single sign-on between servers A and B. Applet is using Notes Corba classes to talk to the servers. We are having the following problem:—

When the user is directed to server B (admin server) by the ICM the applet works fine and the document gets locked. When the user gets directed to server A by the ICM the applets tries to get a session with server B and fails with the following error - “Could not get session”.

Any Ideas???

Thanks
