Hi, On the original note, I understand you just want to restrict guacamole to members of a certain group and while Nick’s filter should work fine, I’m not sure there’s a need to overcomplicate it so much.
I use a filter in a similar fashion and only specify the group. Like so: ldap-user-search-filter: (memberOf=CN= Accounting,ou=groups,OU=Superior Paving Employees,DC=superiorpaving,DC=net) Also, I think there may be some confusion re the ports below. The GC port is 3268, not 389 (non-GC port), not the other way round as mentioned below. I’m also querying the global catalogue port of 3268. This is only required usually if your ldap-user-base-dn: is set at the root of the AD, if you’re using an Org or container under the root then querying 389 should work fine. If ypou change the filter to the one above, does it give you the desired results?

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 On Wednesday, August 9, 2017, 2:26:42 PM EDT, Erik Berndt <erikber...@superiorpaving.net<mailto:erikber...@superiorpaving.net>> wrote: Thanks Nick. I tweaked the search filter a little bit and am able to return the group membership with ldapsearch, but when applying that same filter to guacamole.properties, no users are able to authenticate. Is it possible there is an additional parameter that needs to be used in conjunction with ldap-user-search-filter?

If it still doesn't work, try using that filter in an "ldapsearch" command and make sure you get results back: ldapsearch -H ldap://ad.superiorpaving.net<http://ad.superiorpaving.net> -D <YOUR BIND DN HERE> -W '(&(objectCategory=Group)( sAMAccountName=*)(memberOf=cn= Accounting,ou=groups,ou= Superior Paving Employees,dc=superiorpaving, dc=net))' Should do the trick. If you get no results back or you get an error, fix it and try, again. -Nick On Wednesday, August 9, 2017, 12:46:13 PM EDT, Erik Berndt <erikber...@superiorpaving.net<mailto:erikber...@superiorpaving.net> > wrote: I'm attempting to filter AD groups permitted to login through Guacamole, which is making use of the auth-mysql and auth-ldap extensions. Login works fine for the users defined in the ldap-user-base-dn. When I define the ldap-user-search-filter and reset the servlet container, all users are prevented from loggin in. This is my first time writing ldap filters, so it's very possible this is a syntax issue. My search filter in guacamole.properties is as follows: ldap-user-search-filter; "(&(objectCategory=Group)( sAMAccountName=*)(memberOf=cn= Accounting,ou=groups,ou=" Superior Paving Employees,dc=superiorpaving, dc=net))" Can anyone assist me with this filter? I also have tried to restrict the ldap-user-base-dn to the specific group I want to give access to, but am running into the same issue. Erik Berndt / Systems Administrator
