jndi look up for security

Hi,

I have written a custom login module.(using AbstarctLoginModule)

In its login() method I want to check the user against an active userstore.

To do this I need to look up the securitycontext to get to the userstore.

I tried doing a lookup on "security". This is returning a value of null.

any idea why? Is this because the securitycontext is a non serializable object.

Do I need to use RemoteLoginContext?

please help.

thanks a lot
