we are using a SAP system as user base for our enterprise portal. The authentication is a form based one.

I know that the default loginmodule used is basicpasswordloginmodule.class located in security.jar

I want to implement a new loginmodule similar to the above except that i need one minor change.

for that to happen, i want to know where in the "Basicpasswordloginmodule.class", the acutal verification of username/password is done.. i.e.

I went through the code of BasicPasswordLoginModule.class, but couldnt find the place where it is

where is it talking to SAP system?

which function module is it talking to for verification purpose?

Please help me in this regard.

Thank you

Hi Amit,

Thanks for the reply. but what i am askign for is bit different. I didnt change the authschemes.xml, so by default it should be BasicPasswordLoginModule.

I want to know which RFC is being used for authentication and where can i find in the BasicPasswordLoginModule the calls to that particualr RFC.

would be great if you could help me !
