Bypassing Identity server authentication

Question

I am working on Sun ONE portal 6.0 and its bundled identity server 5.1. I am exploring various methods to authenticate users transparently without login screen being shown.
1. can we pass params through query string something like "http://portal.domain.com/amserver/login?module=LDAP&TOKEN0=uid&TOKEN1=pwd" to achieve it.
2. I have gone thru sso package and tried to find method
to retrieve ssotokenid for web based authentication. I could not find any ??
3. I have gone thru Authentication API whose implementation example is given in ../authentication/LDAP directory. But it is in identity server 6.0
4. Is it possible to write any customised authentication module to authenticate user and retireve cookie to be set on browser ????
Can anybody suggest me solution ???

Answer 1

As of your first Step, you can pass the parameters to the amserver login module and authenticate the user against the authentication backend. This is not By passing the Identiy Server itself. Its a way of authenticating the user without going throught the login sreen of that perticular module.
As per I know you can develop your own authentication module and pass the cookie that you want to pass and carry the session.
