Thanks for the reply. I am using Windows AD not Azure AD and also I tried with MySQL on Ubuntu. The MySQL authentication works well, but the LDAP Authentication still gives me the same error:WARN o.a.g.e.AuthenticationProviderFacade - The "ldap" authentication provider has encountered an internal error which will halt the authentication process. If this is unexpected or you are the developer of this authentication provider, you may wish to enable debug-level logging. If this is expected and you wish to ignore such failures in the future, please set "skip-if-unavailable: ldap" within your guacamole.propertiesI have configured the logs to be at the debug level, but could not find anything helpful either for catalina.out or syslog
