We are in the process of enabling SSO using LTPA in one environment: Webseal -> IHS -> WAS.

Ltpa token seems lost between IHS and WAS.

Interestingly, when we link Webseal -> WAS directly, SSO working fine, but when test practical architecture, e.g:  Webseal -> IHS -> WAS, we found out LTPA token in IHS log, but not within WAS log, LTPA token just gone, and of course SSO doesn’t work properly.

Any help will appreciate.
