Hi,
I use Roundcube with OIDC. Everything works fine in Dovecot 2.3.20, but broke in 2.3.21. Downgrading to 2.3.20 makes it work again, so it is introduced in the newer release.
Error (2.3.21):
Oct 4 11:03:57 mx dovecot[558531]: imap-login: Disconnected: Connection closed (client didn't finish SASL auth, waited 1 secs): user=<christian@roessner.email>, orig_user=<christian@roessner.email>, method=XOAUTH2, rip=192.168.0.4, lip=192.168.0.2, TLS, TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits)Here is an example with 2.3.20:

I get a different error from RC:

Thanks in advance

Can you provide auth_debug=yes logs?
