Thanks for the in-depth explanation!
Good article. When troubleshooting operations – like user login issues or connectivity to AD – there are a couple of notes to consider:
> When looking for anything in particular, remember the logs are kept in UTC time – so keep timezone differences in mind. Do NOT change the timezone on the appliances.
> The appliances are in pairs and run in active-active mode. You should best open two SSH (e.g. Putty) windows and connect to the 169.254.x.x address of both appliances, then run the tail command to check what happens on both simultaneously.
> When looking for errors you might want to pipe and grep the output for keywords like ERROR or username:
tail -f /var/log/desktone/desktone.log | grep ERROR
> You might opt for automatic downloading of logs using an additional server like a Nagios Log server – which would need to be able to connect to the same network.
