I am using Roundcube webmail, keycloak, and mailcow server in docker, I have integrated keycloak with Roundcube. I have given mailcow server’s IMAP and SMTP configuration to Roundcube webmail client. I can able to login to Roundcube with mailcow server’s users, But I can’t login with keycloak created user. It shows login failed error.
I have put this issue in the official Roundcube GitHub but they told that configure the xoauth in mailcow server. Thats why I came here, guys. The below is I created a ticket in Roundcube GitHub
My question is How to be configured to accept XOAUTH access tokens and to validate them in mailcow server??
