I recently noticed a warning banner in ISE Policy Set but I have read all the bug IDs and Release Notes - does anyone have a worked example in ISE Policy Set to illustrate what this means ? I don't which attributes can evaluate to null??? The langua...

The Catalyst Center restricted shell (maglev) doesn't allow the most basic operation to clear out the SSH known_hosts file with standard unix tools like ssh-keygen. In addition, as maglev user, the ~/.ssh/known_hosts file is not viewable or editable...
