Symantec Adapter libraries for Siteminder integration use HTTP 1.0 to interact with ArcotSM.
This doesn't work in customer's production environment, where WAFs block HTTP < 1.1.
When using Siteminder Adapter shim authentication, users get the error "unable to retrieve token".
Adapter shim has used HTTP 1.0 while creating a token with State Manager.
Release : 9.1 SP1
Component : Strong Authentication (Arcot WebFort)
For HTTP 1.1 support, Hotfix CA-SiteMinderAdapter-9.1.01-DE486825-Hotfix needs to applied on top of 9.1SP1 and it will be available in next release for all customers.
