Hi Gaurav,

In WebSphere you implement was is called a Custom Registry. You have to implement the interface com.ibm.websphere.security.UserRegistry and add some jar files to your classpath to compile with. Implement the interface and modify the methods to suit your implementation.

You can find the details and an example in the IBM WebSphere V5.0 Security redbook which can be obtained free of charge from:
