Shibboleth, OpenSAML Fatal Profile Exception
I get an error similar to the one below when I try to access a Shibboleth login: opensaml::FatalProfileException at (https://illinois.edu/Shibboleth.sso/SAML2/POST)
SAML response contained an error.
Error from identity provider:
This error usually indicates a cookie or active login error (Shib does not like multiple users signed into the same browser at the same time). To resolve this issue, please clear your browser's cookies and cache (and active logins, if it is an option), then restart your browser. Alternatively, trying a different browser should also resolve the issue.
