Mike Jumper commented on GUACAMOLE-1608: ---------------------------------------- {quote} However, we currently have to change the authentication method to password, but most of the posrgresql versions prior to 14 use md5. Is it possible to change the default on the Guacamole side to md5? {quote} I don't believe it's the connecting PostgreSQL client (Guacamole) that controls which auth mechanisms are accepted. As you show in your screenshot of the {{postgres}} Docker image configuration options, they provide an option to allow you to override the accepted auth mechanism for the PostgreSQL server, automatically updating PostgreSQL's {{pg_hba.conf}}. Auth using the "md5" method should already be working. I use Guacamole myself with a PostgreSQL database that has been configured to accept the "md5" method, and things work as expected. > Change auth method in postgresql > -------------------------------- > > Key: GUACAMOLE-1608 > URL: https://issues.apache.org/jira/browse/GUACAMOLE-1608 > Project: Guacamole > Issue Type: Improvement > Components: guacamole-auth-jdbc-postgresql > Reporter: Ruk Doe > Priority: Minor > Fix For: 1.6.0 > > Attachments: image-2022-05-17-23-11-30-237.png > > > The auth method has changed in postgresql, but is not supported in guacamole. > !image-2022-05-17-23-11-30-237.png! -- This message was sent by Atlassian Jira (v8.20.7#820007)
