Authenticate SWA exposed through Front Door with AAD.

[andreaskasc]

Hi Everyone,

I have a SWA that I want to authenticate with AAD (using also an app registration). Following the documentation I successfully do that with attached config (let's say that my swa url is swa.com):
swa.config.txt

I also have a custom domain (let's call it mydomain.com) and I have created a route so that my swa is exposed through FD from url mydomain.com/swa. Here is where the problem starts. When going to mydomain.com/swa I am redirected to mydomain.com/.auth/login/aad... which is not correct and it gives me 404.
I have also tried to hardcode the redirection to swa.com/.auth/login/aad?post_login_redirect_uri=mydomain.com/doc. This doesn't produce any error but after the authentication flow is complete it doesn't redirect back to mydomain.com/swa as I would expect by setting post_login_redirect_uri. It just stays to swa.com.

Any ideas if my requirement is achievable through SWA configuration?

Best regards,
Andreas
