      @viktor_g I did spot the docs about the required group, but didn't about the patch! Thank you, I'll upgrade and see if it's fixed.

        @viktor_g I've upgraded pfSense to latest stable 2.4.5 and, with my disappointment, a patch merged nearly one year ago isn't present yet :(
        I manually patched auth.inc but I'm still unable to filter users by group.
        If I disable the Extended query param and perform a test auth pfSense now fetches user groups.

        But if I add (&(objectClass=posixGroup)(cn=openvpn)(memberUid=*)) to the extended query filter in order to restrict only users in the openvpn group then auth will fail.

          @maxxer can you show your server's LDAP group object in LDIF format?

              Hi,
              every time, when I try to change "Group member attribute" from memberUid to others I see wrong filter in my logs on LDAP server:

              example:
              filter: (&(objectClass=posixGroup)(memberUid=test@gmail.com)) - correct
              filter: (&(objectClass=posixGroup)(?memberuida=test@gmail.com)) - wrong, I know "memberuida" as attribute not exist, but why arrtibute has "?name"
              filter: (&(objectClass=groupOfUniqueNames)(memberUid=test@gmail.com)) - wrong objectClass BUT! attribute is ok: "memberUid"

              filter: (&(objectClass=groupOfUniqueNames)(?memberOf=test@gmail.com)) - wrong, attributes "?memberOf"
              filter: (&(objectClass=groupOfUniqueNames)(?uniqueMember=%s=test@gmail.com)) - wrong "?unique...."

              Why if attributes != memberuid, they are changed to "?attribute" ?
              This is probably why the groups are not showing up :/

                  Hi, I'm having the same problem, has anyone found a solution?

                  Today I have my openvpn and firewall in separate services on bsd, everything works perfectly, but it's an old machine, I need to update the services, I'm migrating to pfsense, and I can't manage the filter by groups.
                  I installed version 2.7.0 of pfsense, I found several videos and documents of people using the "extended query", but they were all Microsoft AD.

                  I use Openldap, monitoring the ldap server, I saw that the extended query for the group goes together with the user filter, because of this all the rules fail authentication

                  I have tested user filters and it works well.
                  No group filter parameters work.

                      This is exactly my problem, surprised to be on the list for a year.

                      Based on Jim Pingle's solution, I made several attempts, even using Apache Directory Studio, I came up with a solution,

                      Jim Pingle Solution
                      &(objectClass=posixGroup)(cn=VPNUsers)(memberUid=) --> doesn't work for me
                      &(objectClass=posixGroup)(cn=VPNUsers)(member=) --> works for me

                      Jim Pingle Result
                      (&(memberUid=jimp)(&(objectClass=posixGroup)(cn=VPNUsers)(memberUid=*)))

                      My result
                      (&(member=uid=jimp,ou=people,dc=myserver,dc=example,dc=com)(&(objectClass=posixGroup)(cn=VPNUsers)(member=*)))

                      Detail that I needed to change,
                      Group member Attribute = member
                      Didn't work with memberOf or memberUid

                      My version
                      OpenLDAP: slapd (May 23 2018 04:25:19) $
                      Debian OpenLDAP Maintainers

                      Thank you very much for your feedback
