You can add additional entries to the hosts file for the Advanced Authentication appliance. You must add the entry to the /opt/aauth/docker-compose.yml file. This is a manual process. You cannot change the host entries in any other way.
Access the command line console of the appliance.
Run the following command.
vi /opt/aauth/docker-compose.yml
Add extra_hosts to redis section in the format <FDQN>:<IP>.
For example:
extra_hosts:
- "hostname1.domain.com:1.1.1.1"
- "hostname2.domain.com:2.2.2.2"
Save and close the file.
Reboot the appliance.
