[BUG] IRIS_ADM_USERNAME not enforced

[juadde]

Describe the bug
When set, IRIS_ADM_USERNAME is not enforced, resulting on an administrator with the username administrator instead of set username.

To Reproduce
Steps to reproduce the behavior:

1. Get latest IRIS
2. Copy .env.model to .env
3. Uncomment IRIS_ADM_USERNAME line and set it to something else that administrator (admin for example)
4. Run docker-compose up
5. See creation of administrator instead of admin in the logs docker logs iriswebapp_app (You can now login with user administrator and password XXX)
6. Try to login at https://localhost:443 with admin username (or the set username if different), it fails
7. Try to login at https://localhost:443 with administrator username, it succeed

Expected behavior
I expect the administrator to be created with the username set in the .env file.

Server:

• OS: Ubuntu 22
• Docker: 20.10.21, build 20.10.21-0ubuntu1~22.04.2
• IRIS Version: 2.0.2

Desktop:

• OS: Ubuntu 22
• Browser: Firefox 112.0
• IRIS Version: 2.0.2

Additional context
This feature will be useful for LDAP authentication.

Hi @juadde

Indeed there's an issue in the configuration.py. The IRIS_ADM_USERNAME isn't propagated in the app config. It will be fixed in the next release 👍
