We are trying to implement SSO xCP2.0 xCelerator using CA Siteminder in our application and are stuck at one point (We have followed the steps given in the xCelerator documentation). Below is the exception we are getting. Wanted to check with you if someone has encountered this issue and can help us in resolving -
