TOTP PSQLException following successful LDAP authentication




      I have successfully deployed both guacd and guacamole via docker image to AWS ECS. I have added the TOTP extension to the image. Additionally, I have successfully configured guacamole to use LDAPs to integrate with a Microsoft Active Directory and a Postgres database.


      I can see via in the guacamole logs, that a login attempt is successfully authenticated by the configured LDAPs.

      15:25:40.889 [http-nio-8080-exec-4] INFO o.a.g.r.auth.AuthenticationService - User "<user-name>" successfully authenticated from <ip-address>.

      I have additionally verified that the same login attempt (with the same user/credentials) will result in successful login and access to the guacamole application when I temporarily deploy WITHOUT the TOTP extension for testing purposes. As I require the MFA protection provided by TOTP, this is not an acceptable option in this situation.

      The problem:

      In response to this successful login, the TOTP plugin proceeds to attempt to add/update the associated user in the Postgres DB. This fails as is shown in the following guacamole log entries.

      15:25:41.003 [http-nio-8080-exec-4] ERROR o.a.g.rest.RESTExceptionMapper - Unexpected internal error:
