I’m trying to enable the AD authentication, but failed. use use the docker to run the stash.
here is the doocker-compose.yml

– here is the Dockerfile.
[root@localhost redash]# cat Dockerfile
FROM redash/redash:10.1.0.b50633
COPY ./python-packages/*.whl /tmp/
RUN pip install /tmp/pyasn1-0.4.8-py2.py3-none-any.whl
RUN pip install /tmp/ldap3-2.9.1-py2.py3-none-any.whl

I original use the RUN pip ldap3 in dockerfile as suggestion of document. but it always fail to download the ldap3, maybe my server network has issue, anyway, I download the ldap3, and install it from local.

– here is the evn.

I rebuilt everything and start the container.
docker-compose down
docker-compose up -d

then opened the login page of redash.
when I click the login. I got erros as below

# Internal Server Error

The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

checked the logs, I got TypeError: cannot convert ‘NoneType’ object to bytes.
docker-compose logs -f
