Hello everyone, I am currently setting up Apache Guacamole (version 1.6.0) and although I can now successfully access the Web GUI, I still cannot log in. I would appreciate your help solving this issue.
*Environment details:* - Guacamole 1.6.0 - guacd 1.6.0 - Tomcat 9 - MariaDB (external Galera cluster) - MySQL authentication extension - Debian-based Linux ------------------------------ *Issue description* The GUI loads correctly, and the JDBC driver issue has been resolved. However, whenever I try to log in (using *guacadmin*), authentication fails. When I check Tomcat’s status or logs, I consistently see the following warnings: WARN o.a.g.e.AuthenticationProviderFacade - Authentication attempt ignored because the relevant authentication provider could not be loaded. Please check for errors earlier in the logs. WARN o.a.g.event.EventLoggingListener - Authentication attempt from 192.168.0.1 for user "guacadmin" failed: unknown error (no specific failure recorded) There are no clear error messages indicating why the authentication provider is not being loaded. ------------------------------ *Strange SQL output* When I inspect the user table using: SELECT * FROM guacamole_user; I still see strange or binary-like characters in the password_hash and password_salt fields. Example: | password_hash | =�Fp�xe�Զӷ�Ў���i8E�a�x | | password_salt | ��J[*m | I am not sure whether this is expected binary data, an encoding issue, or something related to Galera replication. ------------------------------ *What is working* - Database connectivity (after switching to the MariaDB JDBC driver) - Web interface loads normally - Galera cluster is healthy - Schema import completed without visible errors ------------------------------ *My questions* 1. Why is the authentication provider not being loaded correctly? 2. Are the binary-looking password hashes normal for Guacamole? 3. Could the Galera cluster setup cause issues with these fields? 4. Is there a recommended way to verify or recreate the default *guacadmin* user? I can provide more logs or configuration details if needed. Thanks a lot in advance for your help! Best regards, Felix
