For me, the Require group groupname is working fine, subject to these conditions:
1) There is only one group - might work with multiple, haven't tested
2) Prefix domain e.g. require group "DOMAINNAME\ACL_USERS_LIST"

Third thing I found was not all DLs can be used for authentication. To test this, share a folder and grant access only to the group and see it that group can be added/groupmembers can access the shared folder
