I have a functioning 2.15 IdP. Tomcat was upgraded from 6.029 to 6.035. Our SSO is now failing with a SAML error Authn:AuthenticationFailed. All IdP configuration and Tomcat conf files are the same? Has any one solved this problem. Thank you, Kathy Kathy E. Wright CCIT/Clemson University kewrig at clemson.edu (864)656-8133
