NetWorker: authc-kommandon misslyckas med felmeddelandet "unable to find valid certification path"

Summary: authc_config- och authc_mgmt-kommandon misslyckas i NetWorker-rapporteringen "unable to find valid certification path to requested target".

This article applies to This article does not apply to This article is not tied to any specific product. Not all product versions are identified in this article.

Symptoms

  • NetWorker-servern distribueras på ett fristående system (icke-klustrat).
  • NetWorker-auktoriseringskommandon (authc_config, authc_mgmt) misslyckas och följande fel rapporteras:
[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

 

  • Det här problemet uppstår oavsett om du använder lokal NetWorker-autentisering eller extern (LDAP)-autentisering.

 

Cause

Det finns en felmatchning i signaturen för emcauthctomcat-certifikaten. Emcauthctomcat konfigureras som standard under NetWorker-distributionen. Det här certifikatet finns på tre ställen:

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\NRE\java\jre#.#.#####\lib\security\cacerts

Resolution

Korrigera felet med certifikatet.

  1. Skapa en kopia av de befintliga nyckellagerfilerna:
    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\NRE\java\jre#.#.#####\lib\security\cacerts

     

    Obs! Cacerts-filen hittades i authc:s konfigurerade JRE-instans. Sökvägarna som visas ovan är när NetWorker Runtime Environment (NRE) är installerad. Om Oracle Java JRE är installerat finns cacerts-filen i Java-installationssökvägen under .. \lib\security\cacerts.
  2. Öppna en administratörs- eller rotkommandoprompt på NetWorker-servern.

  3. Stoppa NetWorker-servertjänster:
    Linux: nsr_shutdown
    Windows: net stop nsrd

  4. Ändra katalogen till katalogen JRE \bin.

  5. Använd följande kommandosyntax för att ta bort emcauthctomcat-certifikaten från de nyckellagerplatser där felmatchning observeras.

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

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

    Obs! Lösenordet för Java-nyckellagret, oavsett om NRE eller Oracle jre används, är changeit. Authc-nyckellagret är det användardefinierade lösenordsuppsättningen för nyckellagret när networker-installationsguiden (Windows) används eller skriptet /opt/nsr/authc-server/scripts/authc_configure.sh (Linux).

Exempel:

[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]#

 

  1. Standardcertifikatet emcauthctomcat bör finnas på följande plats:
    Linux: /nsr/authc/conf/emcauthctomcat.cer
    Windows: C:\Program\EMC NetWorker\nsr\authc-server\tomcat\conf\emcauthctomcat.cer

  2. Importera standard-emcauthctomcat-certifikatet till nyckellagren:
    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"

Exempel:

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

[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:

  1. Använd tangenten keytool -list kommando för att bekräfta att emcauthctomcat-signaturer överensstämmer i vart och ett av nyckellagren:
    Linux: ./keytool -list -keystore /path/to/keystore -storepass password | grep -A1 emcauth
    Windows: keytool -list -keystore "C:\path\to\keystore" -storepass password

  2. Starta NetWorker-tjänsterna:
    Linux: systemctl start networker
    Windows: net start nsrd

  3. Försök att använda en authc_config eller authc_mgmt Kommandot:
    authc_config -u Administrator -e find-all-users

Exempel:

[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
