NetWorker：authc 命令失败，并显示“Unable to find valid certification path”

• NetWorker 服务器部署在独立（非群集）系统上。
• NetWorker auth 命令（authc_config、 authc_mgmt） 失败并报告以下错误：

[root@networker-mc bin]# authc_mgmt -u administrator -e find-all-users
Enter password: 
ERROR [main] (DefaultLogger.java:190) - Error executing command. Failure: I/O error on POST request for https://localhost:9090/auth-server/api/v1/sec/authenticate [localhost]: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target; nested exception is javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

• 无论使用本地 NetWorker 身份验证还是外部 （LDAP） 身份验证，都会发生此问题。

emcauthctomcat 证书的签名不匹配。默认情况下，在 NetWorker 部署期间配置 emcauthctomcat。此证书存在于三个位置：

Linux：

• /nsr/authc/conf/authc.keystore
• /opt/nsr/authc-server/conf/authc.truststore
• /opt/nre/java/latest/lib/security/cacerts

Windows：

• C：\Program Files\EMC NetWorker\nsr\authc-server\tomcat\conf\authc.keystore
• C：\Program Files\EMC NetWorker\nsr\authc-server\conf\authc.truststore
• C：\Program Files\NRE\java\jre#.#.#_###\lib\security\cacerts

更正证书不匹配。

1. 创建现有密钥库文件的拷贝：
   Linux：

   • /nsr/authc/conf/authc.keystore
   • /opt/nsr/authc-server/conf/authc.truststore
   • /opt/nre/java/latest/lib/security/cacerts

   Windows：

   • C：\Program Files\EMC NetWorker\nsr\authc-server\tomcat\conf\authc.keystore
   • C：\Program Files\EMC NetWorker\nsr\authc-server\conf\authc.truststore
   • C：\Program Files\NRE\java\jre#.#.#_###\lib\security\cacerts

    

   提醒：cacerts 文件可在 authc 配置的 JRE 实例中找到。上面显示的路径是安装 NetWorker Runtime Environment （NRE） 时。如果安装了 Oracle Java JRE，则 cacerts 文件位于 .下的 java 安装路径中。\lib\security\cacerts。

2. 在 NetWorker 服务器上，打开 admin 或 root 命令提示符。

3. 停止 NetWorker 服务器服务：
   Linux： nsr_shutdown
   Windows： net stop nsrd

4. 将目录更改为 JRE \bin 目录。

5. 使用以下命令语法，从观察到不匹配的密钥库位置删除 emcauthctomcat 证书。

   Linux：
   ./keytool -delete -alias emcauthctomcat -keystore /path/to/keystore -storepass password

   Windows：
   keytool -delete -alias emcauthctomcat -keystore "C:\path\to\keystore" -storepass password

   提醒：Java 密钥库密码（无论 NRE 还是 Oracle jre）是 changeit。authc 密钥库是使用 NetWorker 安装向导 （Windows） 或 /opt/nsr/authc-server/scripts/authc_configure.sh 脚本 （Linux） 时设置的用户定义的密钥库密码。

Example:

[root@networker-mc bin]# ./keytool -delete -alias emcauthctomcat -keystore /opt/nre/java/latest/lib/security/cacerts -storepass changeit  

[root@networker-mc bin]# ./keytool -delete -alias emcauthctomcat -keystore /opt/nsr/authc-server/conf/authc.truststore
Enter keystore password:  
[root@networker-mc bin]#

6. 默认 emcauthctomcat 证书应存在于以下位置：
   Linux：/nsr/authc/conf/emcauthctomcat.cer
   Windows：C：\Program Files\EMC NetWorker\nsr\authc-server\tomcat\conf\emcauthctomcat.cer

7. 将默认 emcauthctomcat 证书导入密钥库位置：
   Linux：
   ./keytool -import -alias emcauthctomcat -keystore /path/to/keystore -storepass password -file /nsr/authc/conf/emcauthctomcat.cer

   Windows：
   keytool -import -alias emcauthctomcat -keystore "C:\path\to\keystore" -storepass password -file "C:\Program Files\EMC NetWorker\nsr\authc-server\tomcat\conf\emcauthctomcat.cer"

Example:

[root@networker-mc bin]# ./keytool -import -alias emcauthctomcat -keystore /opt/nsr/authc-server/conf/authc.truststore  -file /nsr/authc/conf/emcauthctomcat.cer
Enter keystore password:

Trust this certificate? [no]:  y
Certificate was added to keystore
[root@networker-mc bin]# ./keytool -import -alias emcauthctomcat -keystore /opt/nre/java/latest/lib/security/cacerts -file /nsr/authc/conf/emcauthctomcat.cer   
Enter keystore password:  
Certificate already exists in keystore under alias <emcnwuiserv>
Do you still want to add it? [no]:  y
Certificate was added to keystore

8. 使用 keytool -list 命令以确认每个密钥库中的 emcauthctomcat 签名匹配：
   Linux： ./keytool -list -keystore /path/to/keystore -storepass password | grep -A1 emcauth
   Windows： keytool -list -keystore "C:\path\to\keystore" -storepass password

9. 启动 NetWorker 服务：
   Linux： systemctl start networker
   Windows： net start nsrd

10. 尝试使用 authc_config 或者 authc_mgmt 命令：
    authc_config -u Administrator -e find-all-users

Example:

[root@networker-mc bin]# authc_mgmt -u administrator -e find-all-users
Enter password: 
The query returns 2 records.
User Id User Name           
1000    administrator       
1001    svc_nmc_networker-mc
