ldap - Ranger LDAP 統合のユーザー/グループ同期の問題

Question

Ranger バージョン 1.2.0 を使用しています。LDAP ユーザー/グループ同期と統合しようとしています。以下はレンジャーの構成です。

Bind User: uid=admin,o=Mobility
Username Attribute : cn
User Object Class​ : inetOrgPerson
User Search Base : ou=Users,o=Mobility
​User Search Filter : (&(objectClass=inetOrgPerson)(cn=?))
User Search Scope : cn
User Group Name Attribute : cn
Group Member Attribute : member
Group Name Attribute : cn
Group Object Class : groupOfNames
Group Search Base : ou=Groups,o=Mobility
Group Search Filter : (&(objectClass=groupOfNames)(cn=?))

以下はLDAP構成のスクリーンショットです

以下は、レンジャーのauth.logで取得しているログです
