[389-users] Dynamic Group Query Not Returning Members

Hi There, I'm trying to set up dynamic groups with 389 DS (1.3.7.5 B2018.184.1411) but my queries against it don't seem to be returning any members. I have a user set up like this: objectClass: eduPerson objectClass: inetLocalMailRecipient objectClass: inetOrgPerson objectClass: inetUser objectClass: organizationalPerson objectClass: person objectClass: posixAccount objectClass: top cn: Test Abc gidNumber: <redacted> homeDirectory: /home/testabc sn: Abc uid: testabc uidNumber: <redacted> displayName: Test Abc givenName: Test loginShell: /bin/bash userPassword:: <redacted> I have my dynamic group set up like this: objectClass: groupOfUniqueNames objectClass: groupOfURLs objectClass: top cn: DynGroup-Test-UniqueMembers description: uniqueMembers test memberURL: ldap:///ou=PEOPLE,dc=test?objectClass?sub?(sn=Abc) The memberURL: ldap:///ou=PEOPLE,dc=test?objectClass?sub?(sn=Abc) returns uid=testabc However my query of the dynamic group doesn't return anything: ldapsearch -x -D "cn=Directory Manager" -W -b " ou=Groups,dc=test" -s sub -a always -z 1000 "(uniqueMember=uid=testabc,ou=PEOPLE,dc=test)" "objectClass" Thanks in advance for your help.
