Integrating "Shibboleth" single sign on into Forms 11g

Hi,

 

We are trying to use "Shibboleth" as our single sign on solution for Oracle Forms 11g.

 

With "Shibboleth" the logged in user name is stored in a web server cgi environment variable "REMOTE_USER".

Is anyone aware of how I can run an Oracle Form connected as this named user by interrogating the environment variable from WITHIN a Forms application.

 

Do I have to do some configuration ?

I do not want to put any user information on the URL command line due to security considerations!

 

e.g.

Could I start the Form as a generic user and then pick up the remote user in a "WHEN-NEW-FORM-INSTANCE" or "PRE-FORM" trigger and run a packaged procedure that would run an "execute immediate" to reconnect as the required user.
