将 LDAP 添加到 nsswitch 后，NFSv4.1 挂载上的 LS 命令在文件夹上挂起

• ONTAP 9
• Linux
• NFSv4.1
• LDAP
• 名称服务（NSSWITCH）

• 共享上的长列表挂起，无法在共享中显示文件夹的内容
• 在相同装载路径上，另一个文件夹可以访问并可以显示信息
• 数据包跟踪显示 NFS 错误延迟
• EMS logs 显示多个客户端（包括受影响的客户端）的 secd.unixLookupFailure 错误：

<node_name> ERROR         secd.unixLookupFailure: UNIX lookup failure on Vserver (vserver_name) for client with IP address (10.1.1.99). Error: Acquire UNIX credentials procedure failed
