问题描述
有关Active Directory LDAP 和集群模式Data ONTAP的更多详细和最新信息,请参见 TR-4073:《 安全统一身份验证》。
在集群模式下使用LDAP时、secd会利用mhost进程""。此过程负责用户身份验证(名称映射)。名称映射中出现的问题会记录到 /mroot/etc/mlog 文件中的secd日志中。
默认情况下、除非指定、否则名称映射失败不会记录在secd日志::*> diag secd trace set -node node-01 -module-names name-mapping -trace-all YES
 Trace spec set successfully.
 
 ::*> diag secd trace show -node node-01
 Trace Spec
 ---------------------------------------
 TraceAll:                     Tracing all RPCs
 Modules:                      NameMapping
 中:此行为在Data ONTAP 7-模式中相同、其中 options cifs.trace_login 必须启用才能查看日志中的跟踪匹配失败。
如果名称映射失败、则会显示以下内容:Thu Sep 15 2011 16:55:38 -04:00 [kern_secd:info:2402] |------------------------------------------------------------------------------
