Hi,

I have set remote user header in my helm chart like below.

extraenvs:
      REMOTE_USER_HEADER: "HTTP_X_CUSTOM_CLAIM_EMAIL"

but when I use Postman to send this header(X-Custom-Claim-email: xyz@abc) its not giving the result as expected(not logged in).

when I check by using curl, its showing header is going

curl -H "X-Custom-Claim-email: abc@xyz.dev" https://healthchecks.xyz.dev -v

Are you running at least v1.18.0?

I started a dev server like so:

$ REMOTE_USER_HEADER=HTTP_X_CUSTOM_CLAIM_EMAIL ./manage.py runserver

In Firefox, I installed a "Modify Header Value" addon, and configured it to add a X-Custom-Claim-Email header:

After doing that, I opened http://localhost:8080 and was logged in:

I am having linuxserver/healthchecks: amd64-version-v1.16.0 does it require at least v1.18.0?

I am sorry to reopen this issue, but i have been stuck with this problem for a while now.
I have been using linuxserver/healthchecks: amd64-version-v1.22.0 and it just am not able to get it working.
I add REMOTE_USER_HEADER = "HTTP_X_CUSTOM_CLAIM_EMAIL" to local_settings.py and send a request containing the X-Custom-Claim-Email header but it doesn't do anything and normal login also stops working.

Hi @Mikhail5555 – in settings.py, there is this bit:

REMOTE_USER_HEADER = os.getenv("REMOTE_USER_HEADER")
if REMOTE_USER_HEADER:
    AUTHENTICATION_BACKENDS = ("hc.accounts.backends.CustomHeaderBackend",)

So, if you pass REMOTE_USER_HEADER as environment variable, it adjusts AUTHENTICATION_BACKENDS. But if you define it in local_settings.py, it doesn't – because it imports local_settings.py at the very end.

To fix, try adding this line to local_settings.py:

AUTHENTICATION_BACKENDS = ("hc.accounts.backends.CustomHeaderBackend",)

Thank you! That indeed solved it!
I though i was going crazy, already spend so much time on trying to get this working. For some reason i though local_settings.py just created an environment variable, but it overwrites the settings.py
