Github user rhtyd commented on the issue: https://github.com/apache/cloudstack/pull/1684 @abhinandanprateek 4.9+ does not contain commands.properties so which is why dynamic roles is enabled for them (by default). When upgrading, if you or @pdion891 upgraded using maven/git code and not packages you won't have commands.properties file and login won't work if dynamic roles is not enabled, but for existing deployments login should work who will have commands.properties in their classpath.
