We recently applied a hotfix to our Blackboard instance and went from version 8.0.260.7 to 8.0.375.9. The SSL cert for our blackboard instance also expired around the same time and one or both of these seems to have broken our CPIP/GCF SSO. We have been unable to get the GCF working since then. From the logs, I do see successful authentication, but we seem to be signed out immediately thereafter. The only error I see in our cpipconnector logs are for

java.lang.IllegalAccessException: Class org.apache.commons.httpclient.HttpConnection can not access a member of class com.sun.net.ssl.internal.ssl.BaseSSLSocketImpl with modifiers "public final"

I ran a checkssl command to import the new cert and while I am not prompted to approve the import, I do get the message

>> checkssl blackboard-test.shu.edu 443
Trying SSL connection with blackboard-test.shu.edu:443
SSL connection was successfully established with blackboard-test.shu.edu:443

Could the certificate keystore be corrupt? Anyone know of a good way to validate the keystore?

Also has anyone else encountered broken GCFs with upgrades to Blackboard specifically version 8? We are scheduled to upgrade to 9 later this summer and if there are others already at 9 and willing to share their experiences with GCF, I would appreciate it.

Thanks in advance
