Claims are removed from userinfo response when parsing fields

Hi!

I'm trying to set up Roundcube as webmail for Stalwart with authentication via Authelia.
Authorization works fine when I use default fields configuration, i.e.

fields.email = "email"
fields.username = "preferred_username"
fields.full-name = "name"

But here's a caveat: most email clients (and DAVx5 for Android, for that matter) are easier to setup if my username is the same as my email address ([email protected] instead of just user).
So I'm trying to configure Stalwart to take the username field from email claim:

fields.email = "email"
fields.username = "email"
fields.full-name = "name"

This fails with the following error: ERROR Authentication error (auth.error) listenerId = "imap", localPort = 143, remoteIp = ::1, remotePort = 50578, details = "Unexpected field type in OIDC response", key = "email", value = "null", causedBy = "crates/directory/src/core/dispatch.rs:25", id = "A0001".

I've dug around in the code and noticed that the claims are removed from userinfo response when parsing here.

Is this the intended behavior? What should I do?

Hi,

Try deleting the fields.username = "email" setting, this will make Stalwart use the email as the username.
