Scope
Version: 8.8.2

Solution
Workaround:  Contact Support for a workaround to clear the condition. 

1.  List the alias names for the certificate targets in the keystore
keytool -list -v -keystore /bsc/campusMgr/.keystore -storepass ^8Bradford%23 | grep -i alias

Example:
> keytool -list -v -keystore /bsc/campusMgr/.keystore -storepass ^8Bradford%23 | grep -i alias
Alias name: agent << Persistent Agent
Alias name: portal  << Portal
Alias name: radius  << Local RADIUS Server
Alias name: radius_trust_0  << RADIUS Endpoint Trust
Alias name: tomcat  << Admin UI


2.  Delete the target to which the user certificate was installed from the keystore
keytool -delete -alias <target alias> -keystore /bsc/campusMgr/.keystore -storepass ^8Bradford%23

Example:  User certificate was installed to the Portal target
keytool -delete -alias portal -keystore .keystore -storepass ^8Bradford%23

The Certificate Management view should now be accessible in the UI.

3.  Recreate the deleted target in the Certificate Management list.  Click on another target then click Copy Certificate.
