Scott, I get what you're explaining about the discovery URL. I removed
those attributes entirely since we don't plan on having a discovery service
implemented any time in the near future. I'm able to get my local test to
work properly by setting the entityID to the old one but the ACS URL seems
to be the issue now. I don't know how our users are using the ACS url but
in Jumpcloud you have to specify one & it *only works if I set it to the
domain of the new server: sso.company.com/Shibboleth.sso/SAML2/POST
<http://sso.company.com/Shibboleth.sso/SAML2/POST>*...If i set it to
shibboleth.company.com/Shibboleth.sso/SAML2/POST (which I imagine most of
users have it set to) it doesn't work...Is there any way to get around this
on my end without forcing them to do anything?
