Guacamole LDAP problem

I cannot log in Guacamole. Docker gives a error:
15:40:34.246 [http-nio-8080-exec-9] ERROR o.a.g.a.ldap.LDAPConnectionService - Unable to connect to LDAP server: Connect Error
15:40:34.246 [http-nio-8080-exec-9] ERROR o.a.g.a.l.AuthenticationProviderService - Unable to bind using search DN “cn=guaca-06885987,cn=memberserver,cn=computers,dc=exemple,dc=com”
I use a UCS 4.4 and Guacamole 0.9.13-incubating.
Thanks for helping

Is this the Guacamole by Univention or from Docker Hub?
Univention has modified the image to match their LDAP property names.
There is a Guacamole App available in the UCS App Store.

Hi, thanks. I used the Guacamole App available in the UCS App Store.
I solved this issue, the problem were that my dns did not had an appointment for the UCS server.
Now Guacamole is working, very slow, but working.
Thanks a lot.
