A blank page appears when logging into Strategy Library 2019 using Tivoli authentication, even though in Ddeveloper a third party user already exists with full privileges.
The way ISAM (IBM Security Access Manager) works when protecting an application server is through a junction that is created in Web Seal. This junction functions as a reverse proxy that first hits the ISAM server, requires authentication in order to gain access to the system and then it forwards the request based on the contents of the URL. The situation here that is unique compared to other trusted providers is that the URL gets rewritten to
http://tivoli_machine:port/junction/Strategy/....
http://tivoli_machine:port/Strategyfor certain calls, which ISAM cannot process.
Use the option in Tivoli to create a transparent junction, which will allow the URL to be changed to not include the junction name and leave the URL as any regular URL location:
http://tivoli_machine:port/Strategy. With this new type of junction no URL trimming takes place and the system can be used successfully.
