Guest access with authentication

[UbiquitousBear]

I've enabled LDAP authentication in Jitsi via the addition of an extra set of environment variables in a Secret, and with the helm values declaring enableAuth: true.

When I authenticate to join a meeting, that works well. However, when I try to get a guest to join, they're prompted to login.

Am I missing something with how it's meant to be set up?
