Hi,
I'm trying to connect to an RDP server that is set up with both TLS and NLA. I
want the RDP connection to take place using the username of the guacamole user
who has logged in. (guacamole has been linked with LDAP.) Unfortunately, this
doesn't work: the RDP server disconnects the client immediately (according to
the guacamole web GUI). docker logs guacd merely reports:
guacd[41]: ERROR: Error connecting to RDP server
guacd[41]: INFO: Connection did not succeed
My connection username is set to ${GUAC_USERNAME}. Password is set to
${GUAC_PASSWORD}. Domain box is left blank, security mode set to NLA, and
Ignore server certificate has been checked to work around the issue in my last
e-mail. Everything is left at defaults.
Guacamole is integrated with Active Directory using LDAP, with a PostgreSQL
back-end for configuration. I set up docker to use the userPrincipalName LDAP
attribute for usernames. So e.g. I login to guacamole as "[email protected]".
Note that I am using latest docker images for both guacd and guacamole.
I have verified that logging in with regular Microsoft Remote Desktop client
using the UPN works. So that's not the problem... On the other hand, if I
manually type the UPN into the username box instead of using ${GUAC_USERNAME},
it still doesn't work.
How do I get ${GUAC_USERNAME} to work for logging in to RDP with a UPN?
Best regards,
James Johnston
