Issue #3398: OIDC authentication with docker mail server

Something I thought would be an issue on the previous one I created happened, I created a new issue here https://github.com/casdoor/casdoor/issues/3398 @hsluoyz @dacongda

@hsluoyz @dacongda thanks so much again for your reactivity, everything works as intented with my docker mail server and casdoor now, I can authenticate using OIDC without any issues. I just have to figure out how to provision accounts into docker mail server from the authenticated user, but that's another unrelated issue to casdoor

good to see!
