OAuth2 plus additional accounts not working

[MH]

I use OAuth2 for entering my mailbox with Roundcube. I wanted to add an additional account via this plugin to switch between accounts in one Roundcube session.

When I try switching to the second account, login fails with this error:

IMAP Error: Login failed for <username> against tls://mail.example.com from <IP address>. AUTHENTICATE XOAUTH2: A0002 NO no mechanism available in /srv/data/www/html/roundcube/program/lib/Roundcube/rcube_imap.php

Obviously, Roundcube tries to connect to this server via OAuth2, too, which has to fail. The entered password for the second account is ignored.

I faced the same problem, did you find a solution to the problem?
