UnauthorizedException in auto-detection when using Basic Auth reverse proxy

NIPE-SYSTEMS

Hi,

I’m using Radicale as CalDAV/CardDAV server behind a reverse proxy which is setup according to this documentation: The whole Radicale server is protected via Basic authentication by the reverse proxy (this includes auto-detection URLs). The auto-detection fails with at.bitfire.dav4jvm.exception.UnauthorizedException because it seems that it does not use the provided authentication (username + password) for the account.

Is there a way to get my setup work?

Thanks!

This configuration shouldn’t be a problem. Why do you think that no authentication is used, instead of user name/password are wrong? Does it work when you turn off Basic authentication in your proxy for testing purpose?

Otherwise, can you provide a test account so that I can have a look?

NIPE-SYSTEMS

Thanks for the quick answer!

While enabling debug logging in Radicale, I’ve noticed a misconfiguration in the authentication of Radicale, which causes the problems. After correcting the configuration (changed auth.type from none to http_x_remote_user) another test creating an account with DAVx5 succeeds.

Thanks for the great app!

@NIPE-SYSTEMS Thanks for the update!
