Dex and Azure AD Connector Configuration

[bolanlesd]

Hello folks, I need your help with integrating dex with chaos litmus. I am using an Azure AD connector and also an ingress instead of NodePort. My ingress is using an existing ALB hence used the group name and name of the existing ALB.

I am getting the error when i visit https://chaos.my-domain.com/auth/dex/login.

Bad Request
User session error.

Any help will be appreciated, thanks in advance.

Below is my yaml "dex-deployment.yaml":
