I've successfully configured Jackrabbit and now I'm properly redirected to the Gluu login page. SP metadata file is also properly transported to oxshibboleth container.
But after logging in to Nextcloud, I'm getting error:
`Account not provisioned. Your account is not provisioned, access to this service is thus not possible.`
I've configured TR to pass to SP *Username* parameter, what is confirmed in logs:
```

```
But in Nextcloud logs I'm getting:
```

```
Am I forgetting about something?
