Hi!
It seems there is a bug in the oauth2 driver, it loads the cert files wrong way. I'll make an internal bug report of this.

Hi,
For troubleshooting purposes, I change the read/write permissions on the certs and confirmed 'dovecot' can read them w/o problem, but still seeing the same errors. :( Mizuki

Is the key/cert pair readable by dovecot user? auth process does not run as root.
You can add
service auth {
extra_groups = ssl_cert
}
and chgrp the cert to ssl_cert to allow access to the cert.

I changed some of the tls options following the document, now config is following:
tokeninfo_url = https://keycloak.com/auth/realms/mail/protocol/openid-connect/token introspection_url = https://dovecot:7598e21b-ec34-481f-80d0-059bddae0923@keycloak.com/auth/realm... introspection_mode = post debug = yes rawlog_dir = /tmp/oauth2 #force_introspection = yes username_attribute = username #active_attribute = active #active_value = true tls_ca_cert_file = /etc/pki/CA/certs/incommon-rsa-server-ca.crt tls_cert_file = /etc/pki/dovecot/certs/dovecot.pem tls_key_file = /etc/pki/dovecot/private/dovecot.pem
The debug log is showing now slightly different msg ex:
Dec 5 21:09:59 mktst4 dovecot: auth: Error: oauth2(mizuki,10.0.2.1,<29b4iv+YKuuCx5Tr>): oauth2 failed: Couldn't initialize SSL context: Can't load SSL certificate: There is no valid PEM certificate.
Still not able to connect to the keyclaok server. :(
PS: Dovecot & Keycloak severs are both using the same legit cert/key pair with CA file configured.
Thanks!

Before declaring it not ready for prime time, did you try setting
tls_ca_cert_file = /etc/ssl/certs/ca-certificates.crt
In the oauth2 configuration file as documented in https://doc.dovecot.org/configuration_manual/authentication/oauth2 ?

Hi all,
We'd like to enable OAuth with Keycloak in Dovecot, after enabling 'OAUTHBEARER XOAUTH2' in Dovecot based on online document, I can confirm Dovecot is ready for OAuth using openssl command, however when the auth request comes in, it failed in 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
:443' or 'curl -v https://
