Hi Craig,
On that note, are you able to help point me to any documentation I could read to set this up? I've looked around, but can only see examples where the address has a ?tenant=someid (or similar) query parameter, and nothing mentioning subdomains specifically.
Some of the docs I've looked at are:
https://totara.help/15/docs/what-is-multitenancy
https://help.totaralearning.com/display/DEV/Multitenancy
Thanks,
Kevin
