Starting a custom Authentication Server version

There may be some cases where you need to start a custom authentication service version that does not follow the official update rollout installed with ntk sys update, for example, if you have compatibility issues with the latest version after an update. Follow the steps below to install a previous version.

1. Inspect the images available with command docker images. Authentication Server images are named either dashboard or auth-server and the tag is the version number.
2. Configure the version with command ntk cfg set nas.image appliance.local/dashboard:3.2.3, replacing appliance.local/dashboard:3.2.3 with the selected image from step 1.
3. Restart the Authentication Server by running ntk as restart.

During the next run of ntk sys update you will be asked to update the Authentication Server. Currently automatic updates cannot be used with custom pinned service versions.
