Security Software

Oracle expert,

First of all, I am not sure if I am in the right place for this question.
But We want to customize our login process for single sign-on.
Our system configurations:
web server: Apache
application server: Web Logic 11g
Single Sign-on Server: 10.1.1.4


Description of problems:

We have forms and reports partner applications that we can log into as follows (call it loginURL):
http://host:port/forms/frmserlet

This is how the user logs in:
1. When the user enters the above loginURL, the server somehow determines from this loginURL and redirects
to Siteminder web agent and Siteminder displays the login prompt.
2. Once the user enters the username/password, and authenticated to the Siteminder,
Siteminder redirects to the LDAP Oracle Single Sign-on and
the SSO server displays the OID login prompt.
3. Once the user enters OID username/password, the SSO server logs the user in and redirect to the forms/report
application.

Here is what we are trying to do:

We already have the forms and reports application to works as described above.
We want to customized the login process using Java or JSP.
The purpose is we do not want the user to log in twice: one login through Siteminder and another one through OID.
We already know how to handle step 2 by changing the policy file.
And we also know how to handle step 3.

But we do not know how to handle step 1, just like the forms and reports application.
Our sysadmin said that when she installed the SSO server, the system told her to use this loginURL:
http://host:port/forms/frmserlet

As a developer, I asked sysadmin to configure the system so that when we enter this:
http://host:port/login/login.jsp
we want to see the Siteminder login page as described in step 1.
Basically, instead of "forms/frmserlet", it 's "login/login.jsp".
But our sysadmin said she did not do any special configuration to make it "forms/formserlet"
when she installed the SSO server. One question that kept popping in my mind is that
when our sysadmin installed the Oracle SSO, it must have somehow configure the Apache web server
or the web logic server or something to redirect it to the Siteminder???....

Any way, so this is what we tried:
our sysadmin modified the web config file mod_wl_ohs:
modify mod_wl_ohs via Oracle Enterprise Manager 11g Fusion Middleware Control;
per Oracle documentation recommendation.

And we got this error:

Failure of server APACHE bridge:

No backend server available for connection: timed out after 10 seconds or idempotent set to OFF or method not idempotent.

We already passed the deadline for this application to work and we are seeking a solution to this problem.
Please help!

Thanks,
Binh
