Enum LoginRejection 

pub enum LoginRejection {
    InvalidCredentials,
    Unavailable(Box<dyn Error + Send + Sync>),
}

Why a backend did not issue a token.

Variants

InvalidCredentials

The credentials are not the ones this backend holds.

Becomes the Feature’s declared AuthenticationFailed.

Unavailable(Box<dyn Error + Send + Sync>)

The backend could not answer at all.

Becomes an Undefined Execution Error with a message that says nothing about why, because a directory outage is not something a client should learn from a login attempt. The source stays on this server, in the log.
