Thank you Stephan,

I'm wondering if I can read the track of the status of bug reports? Could you please advice?

No, this is for our own internal reference.

Thanks. Mizuki

enabling 'OAUTHBEARER XOAUTH2' in Dovecot based on online

establishing a SSL connection with Keycloak server on port 443,
shown as following in debug logs. I can confirming using commands
'openssl s_client -connect <keycloak_server>:443' or 'curl -v
https://<keycloak_server/' all returns normal and no errors.
Altering some of the SSL options in dovecot such as 'ssl_ca =
</etc/pki/CA/certs/root_ca.pem' or 'ssl_client_ca_file =
</etc/pki/CA/certs/root_ca.pem' does not help either. The
certificate are NOT self-signed but signed the legit authorities.
So I'm not sure why dovecot could not establish the connections.
