BIG-IP License Error - Permission denied

Scenario:
After a reboot, the BIG-IP returns a licensing error. Reactivating the license does not work as well.

In the qkview output, we see the following:

2009-07-19 22:56:17,428 ERROR [Thread-15] util.F5Error: - An error has occurred while trying to process your request.

java.io.FileNotFoundException: /var/tmp/bigip.license (Permission denied)

Workaround:

Delete /var/tmp/bigip.license file if it exists.

Ensure that the user you are logged into has full premissions / full admin rights to the BIG-IP box.

Reactivate the license file.
