Summary of the issue you are facing:
When configuring team, it’s not possible to add user from other federation, and there is no toggle to enable federated users for that team.
When doing occ –vvv circles:check, output is:
### Checking loopback address.
. The loopback setting is mandatory and can be checked locally.
. The address you need to define here must be a reachable url of your Nextcloud from the hosting server itself.
. By default, the App will use the entry ‘overwrite.cli.url’ from ‘config/config.php’.
* testing current address: <NC address>
- GET request on <NC address>/index.php/csrftoken: 200
- POST request on <NC address>/index.php/apps/circles/async/test-dummy-token/: 200
- Creating async FederatedEvent (took 1ms)
- Waiting for async process to finish (5s)
- Checking status on FederatedEvent Event created too many Wrappers
- You do not have a valid loopback address setup right now.
Please write down a new loopback address to test:
NC address is correct address of Nextcloud instance; entering it as loopback address again, or running occ circles:check (without -vvv) yields
- POST request on <NC address>/index.php/apps/circles/async/test-dummy-token/: 401
Steps to replicate it (hint: details matter!):
-
Do
occ –vvv circles:check -
Create team
-
Try adding federated user
