Hi all,

I’m trying to get Shibboleth SSO (sp v3.0.1) working with Banner Document Management and application externder 7.0 SP1.

I’ve managed to get Shibboleth SSO working with IIS 8.5 and can get a result for ../Shibboleth.sso/Session and the script from here returns expected results after login.

The error that I’m getting is [1]

Has anyone been able to get this working?
If so can you share your bdms.sso.config   or any other relevant config changes required.
