>                 Key: GUACAMOLE-238
>                 URL: https://issues.apache.org/jira/browse/GUACAMOLE-238
>             Project: Guacamole
>          Issue Type: Bug
>          Components: guacamole, guacamole-auth-jdbc-mysql, guacamole-auth-ldap
>    Affects Versions: 0.9.9, 0.9.10-incubating, 0.9.11-incubating
>         Environment: Debian 8.3, Nginx reverse proxy, public SSL
>            Reporter: Jesse Brinson
>            Priority: Minor

> RDP fails immediately on Server 2016 when no username/password are specified in authentication
parameters.  When I manually set username/password, it will connect.
> Domain, hostname, RDP Encryption and port number are the only other set-parameters. (also
tried using different auth types). Server 2012 R2 and back work ok with these variables, and
credentials left blank.
> I've tried updating freerdp to the nightly version, and using Java 7 and 8, still no
success.
> Logs are only showing non-descriptive errors:
