When accessing the Filr appliance directly by IP or DNS name, editing a file with Content Editor works as expected. But, when accessing using the Access Manager load balancer, the content editor reports the error: "Failed to read the document from storage. Contact your server administrator.", and appears to hang Filr. Simply refreshing (f5) the page unlocks, leaving the user on the login screen.
An error is logged in the datamodel log (/var/opt/novell/datamodel-service/logs/datamodel.stderrout.out)
