Active Directory 上的第三方防火墙正在阻止端口 389 和 445
适用场景
- ONTAP 9
- SMB/CIFS
问题描述
- 在尝试访问 Active Directory （ AD ）时， AD 会在尝试连接到端口 389 或 445 时关闭连接。
- 可以通过 tcpdump 查看此信息：
- 我们还可以在 secd/ems 日志中看到此信息：
[Node1: secd: secd.conn.auth.failure:debug]: Vserver (svm1) could not make a connection over the network to server (ip 10.1.2.123, port 445). Error: Operation timed out ().
[Node1: secd: secd.lsa.noServers:debug]: None of the LSA servers configured for Vserver (svm1) are currently accessible via the network.
