disable SPNEGO for pure Java AS 7.4 SP8 with redwood CPS

SSO experts,

We have SPNEGO setup for one of our AS JAVA 7.4 SP8 systems  (NOT a portal!).  SSO works great!

SSO works great for things like:

NWA

http://hostnameFQDN:port/nwa

UME

http://hostnameFQDN:port/useradmin

RedwoodCPS  (v8.33.112) --> we have ETPRJSCHEDULER deployed and we pay for the full version.

http://hostnameFQDN:port/scheduler

My issue is that SOME users don't want to use their AD userID to SSO to the redwood URL above.  They want to put in a different username and a password.  I thought to myself, OK, no big deal, just add the ?spnego=disabled at the end of the URL right?

Well, that doesn't work on the redwood CPS URL above.  it just gets ignored and goes right into SSO!

Now, for the NWA, the ?spnego=disabled DOES work like it is supposed to!  Forcing the username/pass login.

http://hostnameFQDN:port/nwa?spnego=disabled

For the UME, http://hostnameFQDN:port/useradmin?spnego=disabled doesn't work either but it can see the URL gets extended to /webdynpro/dispatcher/sap.com/tc~sec~ume~wd~umeadmin/UmeAdminApp and if you stick ?spnego=disabled at the end of that, it will force username / password.

But at any rate, the point is I want RedwoodCPS to force a userID/pass screen using the http://hostnameFQDN:port/scheduler?spnego=disabled

but this does not work.

I also tried http://hostnameFQDN:port/scheduler/ui?spnego=disabled but still no good.

Any ideas?

thanks
