Re: LDAP_USER_BASE_DN pointing to an AD Security Group

The user used in bind is member of administrator.
I installed the new version of guacamole (0.9.13) but I have the same problem.
If I configure the base-dn like "DC=test,DC=local" I have this error on catalina.out

ERROR o.a.g.a.l.AuthenticationProviderService - Cannot bind with LDAP server: Error while query user DNs.

Hmmm...that's not very useful. Does the user account you're using to bind for the search have access to the other OUs? Generally they do, unless you've specifically locked down that users permissions.

Any error messages in the log file for your application server (Tomcat, JBoss - whatever you're using)?

Hi Nick,
thanks for your reply.
I changed the ldap-user-base-dn like your suggestion ( DC=test,DC=local ), but now nobody can access to guacamole.
I don't use LDAP but samba4 domain controller.

In order to accomplish what you're trying to do, you need to change your base DN to a higher-level. So, the following line:

ldap-user-base-dn: OU=guacamoleou,DC=test,DC=local

would need to be changed to:

Another option is to leave the base DN as you have it, enable Alias Dereferencing (see the manual) and then link any additional users into the guacamoleou OU object.

Finally, there is a JIRA issue out there for changing LDAP behavior such that you can put multiple OUs in, but I don't think it has been implemented, yet.

Hi

I resolved this issue from another ticket comment from Nick

Are you getting any errors in your Tomcat log files?

Can you try pointing at port 3268 on your AD server, instead of the default 389?  There's an issue with querying the global catalog that is in the process of being fixed (PR is open for it), and I think querying the non-GC-port sometimes works.

-Nick


Changing to 3268 seems to have resolved my issue.

I am currently experiencing the same issue here, if targeting a specific OU in Active Directory it works as required however I am now implementing Guac for another client and require targeting multiple OU’s and using the BASE OU and a few groups was the idea but if I don’t specify the OU that the users live in then I can not seem to get it to work and get the same
