Symptoms

NetWorker 集成了外部身份验证。
AD/LDAP 用户间歇性观察到登录失败。本地 NetWorker 帐户(例如,默认管理员帐户)未观察到任何身份验证问题。

NetWorker 身份认证 (authc) 服务器在authc-server-audit.log中报告以下内容:
Linux:/nsr/authc/logs/authc-server-audit.log
Windows:C:\Program Files\EMC NetWorker\nsr\authc-server\tomcat\logs\authc-server-audit.log
2023-11-02T08:12:39.288+0100 INFO Local authentication failed, incorrect username/password
2023-11-02T08:14:50.235+0100 ERROR Authentication failed, user 'default/DOMAIN.com/account', error: Authentication service is unavailable
2023-11-02T08:14:50.235+0100 INFO Authentication failed, user 'default/DOMAIN.com/account', error: Authentication service is unavailable
2023-11-02T08:15:57.139+0100 INFO Local authentication failed, incorrect username/password
2023-11-02T08:17:38.028+0100 INFO Anonymous access
2023-11-02T08:17:38.031+0100 INFO Permission allowed, user 'anonymous' has 'EVERYONE_CONTROL' privilege to read this resource - Version
2023-11-02T08:17:38.545+0100 INFO User with id '1021' has PasswordNeverExpires flag set to true
2023-11-02T08:17:38.546+0100 INFO Authentication is successful, user 'username'
该错误报告不正确的用户名/密码;但是,该问题只是间歇性发生,表明凭据正确无误。

Cause

由于此问题仅出现在外部用户 (AD/LDAP) 上,因此可认为该问题发生在 NetWorker 之外。具体原因可能有所不同。

Resolution

此问题必须由网络和域管理员进行调查。

检查 NetWorker 服务器和 AD 服务器之间的域名系统 (DNS) 解析:

验证 NetWorker 身份认证服务器未观察到高延迟或 AD 服务器的通信问题:
提醒:默认 AD/LDAP 端口为 389。如果集成使用 LDAPS (SSL),则默认端口为 636。
