I have a new implementation of ServiceDesk Plus standard (ver. 9.1, build 9112) that is presenting a bit of a show stopper for me.

We use group policies for setting out IE zone settings for all users and servers in the organization. All of our local Intranet sites work with no issues as does all of our Internet zone settings for all of our day to day operations.

Unfortunately with ServiceDesk plus, when an end user attempts to visit the web site, they are being prompted with a Windows credentials dialog box which causes the SSO to not pass/work. If I disable the GPO the user passes through without any issues and successfully accesses the ServiceDesk Plus website.

I have added http://localhost, https://localhost, the web site address, and the server that is hosting the app to the IE Trusted and Intranet zones with no luck.

Any idea how to fix this as disabling the GPO is not an option.
