StartTLSと自己署名証明書を使用してAmbariをLDAPサーバーと同期させるのに問題があります。Ambariサーバーとldapサーバーは両方とも同じマシン上で実行されています。ドクしかし、LDAPS 構成の場合かどうかはわかりません。
SSL 構成のケースに従って、自己署名証明書を /etc/ambari-server/keys/ldaps-keystore.jks にインポートすると、ambari-server sync-ldap --all を実行すると、ambari サーバーから以下のエラーが発生します。

私はついていきますこのガイドLDAP サーバーをインストールして、すべてのノードから使用できるようにします。私の理解では、StartTLS 接続にはクエリで -Z オプションが必要です。
たとえば、次のクエリ:
ldapsearch -H ldap:// -x -b "dc=example,dc=net" -LLL dn
降伏する
Confidentiality required (13)
Additional information: TLS confidentiality required
その間
ldapsearch -H ldap:// -x -b "dc=example,dc=com" -LLL -Z dn
問題なく動作します。
残念ながら、LDAP に関しては私の知識は非常に限られています。問題を理解している限りでは、Ambari が LDAP を照会するときに -Z オプションが欠落しているのではないかと思います。同期するときに Ambari にそれを追加するように指示する方法はありますか?
答え1
私の問題は、接続に TLS を使用するように強制するように LDAP を構成したことから発生していることがわかりました。
dn: olcDatabase={1}hdb,cn=config
changetype: modify
add: olcSecurity
olcSecurity: tls=1
olcSecurity: tls=10に切り替えました
同期は正常に機能するようになりましたが、ambari-server と LDAP 間の接続は暗号化されなくなったようです。また、getent passwd以前は表示されていなかった LDAP ユーザーがコマンドによって適切に表示されるようになったことにも気付きました。
