No, it has to be a bug, I have tried from cloudrun, load balancer, instance, plesk and it definitely does not work, any alternative?

I know it is a lot to ask, but these settings should be inside the APP and not in a file, thank you very much for your time, for this software and for answering.

Wow, I didn't expect you to make fun of people who try to use your application, I just mentioned that it might be a bug because I'm not the only one who gets it. But no problem, keep it up

I'm using Kimai 2.30.0 with Docker, trying to set up Azure SAML SSO. When I try to log in, I get this generic error message:

I don't see anything useful in the logs:

kimai-kimai-1  | localhost:8001 127.0.0.1 - - [11/Mar/2025:11:34:11 +0100] "GET / HTTP/1.1" 302 626 "-" "curl/7.88.1"

According to the Azure application logs, the login was successful, but I only see this error on the website. How am I supposed to troubleshoot this? How can I learn what this error actually means?

here's my compose file:

services:

  sqldb:
    image: mysql:8.3
    volumes:
      - ./mysql:/var/lib/mysql
    environment:
      - MYSQL_DATABASE=kimai
      - MYSQL_USER=kimaiuser
      - MYSQL_PASSWORD=kimaipassword
      - MYSQL_ROOT_PASSWORD=ROOT_PASSWORD
    command: --default-storage-engine innodb
    restart: unless-stopped
    healthcheck:
      test: mysqladmin -p$$MYSQL_ROOT_PASSWORD ping -h localhost
      interval: 20s
      start_period: 10s
      timeout: 10s
      retries: 3

  kimai:
    image: kimai/kimai2:apache
    volumes:
      - ./data:/opt/kimai/var/data
      - /home/ubuntu/kimai/local.yaml:/opt/kimai/config/packages/local.yaml
      - ./plugins:/opt/kimai/var/plugins
    ports:
      - 8001:8001
    environment:
      - "DATABASE_URL=mysql://kimaiuser:kimaipassword@sqldb/kimai?charset=utf8mb4&serverVersion=8.3.0"
    restart: unless-stopped

local.yaml is like in docs for setting up Azure SSO.

Hi, with docker I tried from different types of installation, azure, plesk, ubuntu+portainer, GCP, the problem may be the proxy or the way it is invoked. the thing is that I could not get SSO to work this way.

Your azure configuration is fine

finally i was able to achieve it using this configuration in plesk https://www.kimai.org/documentation/shared-hosting.html

it doesn't work with PHP 8.3 (you have memory errors) only with 8.1, but I guess a clean install might work for you.

hopefully this will help you, it's a lot of configurations for this purpose, maybe if you pay kevin he can help you, instead of answering with a rock in his hand.

That's opensource software, kevin does a great job and he has to live and maintain this wonderful tool, but hopefully he can at least answer to someone who just asks a question.
