Subject: [External] : Guacamole LDAP Connections
Hello,
I’m working on a POC. We wanted to allow a java swing based application to be
used via guacamole.
As per my application setup, all users are in LDAP (Oracle Unified Direcotry).
I wanted guacamole users to be authenticated and manage connections using LDAP.
I followed the instructions
https://guacamole.apache.org/doc/gug/ldap-auth.html#<https://urldefense.com/v3/__https:/guacamole.apache.org/doc/gug/ldap-auth.html__;!!ACWV5N9M2RV99hQ!KTkqEy8XJJ2UeML-BSwk2a4EvWZxu3CFCZbIZCklzbgWd-FVwfGnCC3BFtw6gJAj9h1SyaQcgyJDPn9M8rNfmAoGxOUXWaBS9O_FE5c$>
Authentication is working fine but I don’t see any Connections available after
login.
Any support to unblock my current situation is very helpful.
Let me know if any logs are needed
Regards
Srinivas
