Hi, we have cas client applications using SAML 1.1 which we recently upgraded to SAML 1.1 V2.6.6.
With one of these applications (= front end) we are experiencing problems when access through cas. These intermitent problems make this application unavailabe and we end changing the SAML version to its prior jar version. (1.1) We have Cas 4.0.1 installed and the client application is under spring/spring security (with srping security cas) version. Following is pom artifacts versions: <org.springframework.version>4.2.2.RELEASE</org.springframework.version> <org.springframework.security.version>4.0.3.RELEASE</org.springframework.security.version> <org.jasig.cas.client.cas-client-core.version>3.2.1</org.jasig.cas.client.cas-client-core.version> <org.opensaml.opensaml.version>2.6.6</org.opensaml.opensaml.version> <commons-codec.commons-codec.version>1.5</commons-codec.commons-codec.version> <org.apache.santuario.xmlsec.version>1.4.3</org.apache.santuario.xmlsec.version> Cas 4.0.1 version has opensaml-2.5.1-1.jar version. Could this difference in version generate some problem with clients or is there any other known issue on this configuration. Cas is running on tomcat .8.5.5 and application is under tomcat 6.0.45. Any comments on this would be greatly appreciated!
