Trying it out...

I'm authenticating via LDAP, and I defined  username=${GUAC_USERNAME} and 
password=${GUAC_PASSWORD} in my guacConfigParameter attribute.

However, in the guacd log I see the following:

guacd[31018]: INFO:     Guacamole proxy daemon (guacd) version 1.1.0 started
guacd[31018]: DEBUG:    Successfully bound socket to host 127.0.0.1, port 4822

guacd[31560]: DEBUG:    Parameter "username" omitted. Using default value of "".
guacd[31560]: DEBUG:    Parameter "password" omitted. Using default value of "".

Why are these two parameters empty?

The connection fails with:

guacd[31560]: INFO:     User "@2227f8e5-4c29-4915-be43-e7733c0811ba" joined 
connection "$c1a45538-302a-4b3a-9625-c0bed633d909" (1 users now present)

guacd[31018]: INFO:     Connection "$c1a45538-302a-4b3a-9625-c0bed633d909" 
removed.

What can I try?
