Unable to pass the logonTicket through WebDispatcher to backend system

Hello,

We currently have scenario like below, our MII system is not load balanced it always uses Central Instance(CI)

Citrix ---> SAPPortal(EP) ----sso-->CI of Backend System (MII with multiple Apps)

With above scenario, we have successfully setup SSO from EP to backend System(CI) with logonTicket

Now we are trying to load Balance the MII apps with WebDispatcher, we Installed/configured web Dispatcher for http load balancing of a MII system, The scenario is like below:

Citrix ---> SAPPortal(EP) ----sso---> [WebDispatcher] ----->Backend Systems (MII with multiple Apps)

In above case, the logonTicket is Not passing all the way to MII system, when user login with with single-Sign-on at Portal it again asks user/password for MII application.

I am realizing that some how webDispatcher is dropping the logonTicket and not passing to backend system. Trying to figure out if there is any parameter to keep the logonTicket and forward to backend System.

Appreciate your help on this matter.

Thanks,

Laxman
