For example, oauth2 for most users, but plain for others? 2 - I had a feeling that when oauth2 authentication fails, dovecot tries to authenticate via plain with the received token. Doesn’t seem logical, but I get my user blocked on my directory server (freeipa) after a few failed oath authentications. If so, can this be prevented?
