Pass form input parameters during login

Question

I would like to add an additional parameter during login as a flag and capture the value as a session variable. Does anyone have any ideas how to do this? The code for the login form is below, and I understand that NQUser and NQPassword are passed as system session variables. Is there any way for me to add an additional input named NQTest and capture NQTest as a session variable?
<form name="logonForm" method="post" action="saw.dll?Dashboard" onsubmit="return SAWLogonWait()" target="_self">
<input type="hidden" name="saveLangPref" value="true">
<input type="hidden" name="icharset" value="us-ascii">
<input type="textbox" name="NQUser" size="25" value="">
<input type="password" name="NQPassword" size="25" value="">
<input type="submit" value="Log In">
</form>
I'd prefer not to pass my variable through the URL due to security concerns: http://oraclebizint.wordpress.com/2007/07/30/customizing-obi-ee-%E2%80%93-go-url-parameters/

Answer 1

My solution is as follows. In the OBIEE Login form, I put a new INPUT parameter called "TEST":
<input type="hidden" id="TEST" name="TEST" value="This is the test value">
Then in instanceconfig.xml within the <ServerInstance> tags, I added the following code to capture the value:
<Auth>
     <UserIdPassword="true">
          <ParamList>
               <Param name="TEST" source="url" nameInSource="TEST">
          </ParamList>
     </UserIdPassword>
</Auth>
Now in the admin tool I can reference my variable value with VALUEOF(NQSESSION.TEST)
