I have tried both user filter (cn=*) and empty with no difference. 22 May 2018 14:57:04 INFO LdapDeltaUserGroupBuilder [UnixUserSyncThread] - LdapDeltaUserGroupBuilder initialization completed with -- ldapUrl: ldap://54.197.148.18:10389, ldapBindDn: cn=ranger,ou=sds,dc=air,dc=org, ldapBindPassword: ***** , ldapAuthenticationMechanism: simple, searchBase: dc=air,dc=org, userSearchBase: [ou=sds,dc=air,dc=org], userSearchScope: 2, userObjectClass: person, userSearchFilter: (cn=*), extendedUserSearchFilter: null, userNameAttribute: cn, userSearchAttributes: [uSNChanged, cn, modifytimestamp], userGroupNameAttributeSet: null, pagedResultsEnabled: true, pagedResultsSize: 500, groupSearchEnabled: true, groupSearchBase: [ou=sds,dc=air,dc=org], groupSearchScope: 2, groupObjectClass: groupOfUniqueNames, groupSearchFilter: , extendedGroupSearchFilter: (&null(|(uniqueMember={0})(uniqueMember={1}))), extendedAllGroupsSearchFilter: null, groupMemberAttributeName: uniqueMember, groupNameAttribute: cn, groupSearchAttributes: [uSNChanged, cn, uniqueMember, modifytimestamp], groupUserMapSyncEnabled: true, groupSearchFirstEnabled: false, userSearchEnabled: false, ldapReferral: ignore 22 May 2018 14:57:04 INFO UserGroupSync [UnixUserSyncThread] - Begin: initial load of user/group from source==>sink 22 May 2018 14:57:04 INFO LdapDeltaUserGroupBuilder [UnixUserSyncThread] - LdapDeltaUserGroupBuilder updateSink started 22 May 2018 14:57:04 INFO LdapDeltaUserGroupBuilder [UnixUserSyncThread] - Performing user search first 22 May 2018 14:57:04 INFO LdapDeltaUserGroupBuilder [UnixUserSyncThread] - extendedUserSearchFilter = (&(objectclass=person)(|(uSNChanged>=0)(modifyTimestamp>=19700101120000Z))(cn=*)) 22 May 2018 14:57:04 INFO LdapDeltaUserGroupBuilder [UnixUserSyncThread] - LdapDeltaUserGroupBuilder.getUsers() completed with user count: 0 22 May 2018 14:57:04 INFO LdapDeltaUserGroupBuilder [UnixUserSyncThread] - extendedAllGroupsSearchFilter = (&(objectclass=groupOfUniqueNames)(|(uSNChanged>=0)(modifyTimestamp>=19700101120000Z))) 22 May 2018 14:57:04 INFO LdapDeltaUserGroupBuilder [UnixUserSyncThread] - timeStampVal = 20180518183001.391Zand currentDeltaSyncTime = 1526668201000 22 May 2018 14:57:04 INFO LdapDeltaUserGroupBuilder [UnixUserSyncThread] - longUserName: cn=ranger,ou=sds,dc=air,dc=org, userName: ranger 22 May 2018 14:57:04 INFO LdapDeltaUserGroupBuilder [UnixUserSyncThread] - longUserName: cn=andrew,ou=sds,dc=air,dc=org, userName: andrew 22 May 2018 14:57:04 INFO LdapDeltaUserGroupBuilder [UnixUserSyncThread] - No. of members in the group students = 2 22 May 2018 14:57:04 INFO LdapDeltaUserGroupBuilder [UnixUserSyncThread] - LdapDeltaUserGroupBuilder.getGroups() completed with group count: 1 22 May 2018 14:57:05 INFO UserGroupSync [UnixUserSyncThread] - End: initial load of user/group from source==>sink 22 May 2018 14:57:05 INFO UserGroupSync [UnixUserSyncThread] - Done initializing user/group source and sink 22 May 2018 14:57:09 INFO UnixAuthenticationService [main] - Enabling Unix Auth Service! 22 May 2018 14:57:09 INFO UnixAuthenticationService [main] - Enabling Protocol: [SSLv2Hello] 22 May 2018 14:57:09 INFO UnixAuthenticationService [main] - Enabling Protocol: [TLSv1] 22 May 2018 14:57:09 INFO UnixAuthenticationService [main] - Enabling Protocol: [TLSv1.1] 22 May 2018 14:57:09 INFO UnixAuthenticationService [main] - Enabling Protocol: [TLSv1.2] ...
