- After submitting credentials on my SAML SSO login screen, I get the error message "Inter-institutional access failure. Please contact your system administrator for assistance."
Follow these steps:
- Check your messages.txt file to see what errors you are getting.
- Generate new metadata from your SSO system and load it to your EZproxy server.
- Generate new metadata from your EZproxy system and load it to your SSO system.
- If version 6.6.2 or newer, update the shibboleth metadata directives -SignResponse=false -SignAssertion=true -EncryptAssertion=false \ based upon the error in the messages.txt file.
This error usually means that the certificates used for SAML authentication have been changed on one or both systems, and the available metadata has not been updated to reflect the new certificates. If the error in the messages.txt file states SAML Assertion is not signed, a signature is required. Change the flag for -SignAssertion= from true to false, which is true of all flags.
The HTML error page can be customized by placing a file named shibfailure.htm into the EZproxy docs directory.
