NetWorker: authc-kommandon på klustrade RHEL-serverrapporter "unable to find valid certification path to requested target."

Summary: NetWorker har installerats på ett RHEL-/CentOS Linux-kluster med High Availability. När du kör authc config-kommandon (authc_config, authc_mgmt) returneras kommandot "unable to find valid certification path to requested target". ...

Symptoms

  • NetWorker-serverdriftsättningen har konfigurerats på RHEL-/CentOS 7.x- eller 8.x Linux-servrar med kluster med hög tillgänglighet. 
  • authc_config - och authc_mgmt-kommandon returnerar ett fel med certifikatsökvägen:

  • När en nod-failover inträffar finns det en felmatchning mellan certifikaten på den delade /nsr-platsen och den lokala /opt/nsr-platsen på den nya aktiva noden:

Obs! När en nod är aktiv länkas /nsr symboliskt till den delade sökvägen (exempel: /nsr_share/nsr). Det är anledningen till att certifikatet matchas i ovanstående utdata när /nsr_share- och /nsr-utdata jämfördes. Den här sökvägen delas mellan noder. Sökvägarna /opt/nsr och /opt/nre (Java) är dock lokala för varje fysisk nod. Certifikatsignaturerna mellan de delade och de "lokala" certifikaten överensstämmer inte.
  • När den andra noden är aktiv matchar certifikaten mellan "lokala" och "delade" sökvägar

Obs! Ange lösenordet för authc-nyckellagret för -storepass-värdet. Lösenordet för authc-nyckellagret konfigureras under den första konfigurationen när skriptet /opt/nsr/authc-server/scripts/authc_configure.sh körs på varje nod.
  • På den nod där alla certifikat matchar observeras inte fel med certifikatsökvägen:
root@NWrhelNodeE:~# authc_mgmt -u Administrator -p 'authc_password' -e find-all-users
The query returns 1 records.
User Id User Name
1000    administrator

Cause

Innan NetWorker-servrar läggs till i klustret med hjälp av /usr/sbin/networker.cluster konfigureras de som fristående servrar. /opt/nsr/authc-server/scripts/authc_configure.sh körs efter installationen och genererar unika certifikat per nod. Certifikaten som används på den delade platsen matchar den nod som var den aktiva noden där den klustrade NWS-resursen ursprungligen startades. 
 

/nsr-katalogen är symboliskt länkad till /nsr_share/nsr-katalogen som flyttas mellan noder beroende på vilken nod som är den aktuella aktiva noden. /opt/nsr/authc-server/conf/authc.truststore är lokal för varje nod och delas inte när en failover inträffar. Efter en nod-failover matchar signaturer för /nsr/authc/conf/authc.keystore emcauthc-certifikatet med /opt/nsr. certifikat på den första noden men inte den aktuella aktiva noden. 

Resolution

Lösning:

Problemet har åtgärdats i följande NetWorker-versioner:
  • 19.8.0.4
  • 19.9.0.2
Uppgradera till någon av de angivna NetWorker-versionerna (eller senare). NetWorker-paket kan hämtas från: https://www.dell.com/support/home/product-support/product/networker/drivers
 
Obs! När NetWorker har uppgraderats och den klustrade NWS-resursen har startats måste du köra /opt/nsr/authc-server/scripts/authc_configure.sh på den nod där certifikatfelmatch har observerats. Det korrigerar felmatchningen.

Alternativ lösning:

1. Gör noden där certifikaten stämmer överens med den aktiva noden i pcs. Exempel på hur du tar reda på detta visas i fältet Symptom. 
2. Logga in på den passiva noden (där certifikaten inte matchar). 
3. Använd kommandot nsrssltrust för att skapa en certifikatfil mot den virtuella klusterresursen: 

nsrsltrust -u https:// cluster-hostname:9090 -certificate_file.cer

Exempel:

root@NWrhelNodeF:~# nsrssltrust -u https://NWrhelClusD.emclab.local:9090 -c emcauthctomcat.cer

        signing algorithm: 1020

Do you trust this certificate(s) entity based on above information? [yes]/[no]:
yes
Https certificate is saved into certfile [emcauthctomcat.cer].

4. Kontrollera att signaturen för det genererade certifikatet matchar signaturen för det delade certifikatet på den aktiva noden:

cd /opt/nre/java/latest/bin
/opt/nre/java/latest/bin/keytool -printcert -file certificate_file.cer | grep SHA256

Exempel:

root@NWrhelNodeF:/opt/nre/java/latest/bin# ./keytool -printcert -file /root/emcauthctomcat.cer | grep SHA256
         SHA256: 4C:A0:07:70:D2:04:4D:A2:F0:87:5A:75:4A:3A:9F:C3:B6:3A:C0:3B:05:F8:9C:F6:81:01:D5:8C:C7:CE:E6:B4

root@NWrhelNodeE:/opt/nre/java/latest/bin# ./keytool -printcert -file /nsr_share/nsr/authc/conf/emcauthctomcat.cer | grep SHA256
         SHA256: 4C:A0:07:70:D2:04:4D:A2:F0:87:5A:75:4A:3A:9F:C3:B6:3A:C0:3B:05:F8:9C:F6:81:01:D5:8C:C7:CE:E6:B4

5. På noden med de inmatchade certifikaten tar du bort de lokala emcauthctomcat-certifikaten från filen authc.truststore och cacerts.

cd /opt/nre/java/latest/bin
./keytool -delete -alias emcauthctomcat -keystore /opt/nre/java/latest/lib/security/cacerts -storepass changeit
./keytool -delete -alias emcauthctomcat -keystore /opt/nsr/authc-server/conf/authc.truststore -storepass 'authc-password'

Obs! Om det lyckas returneras inga utdata.

6. Importera certifikatet som genereras med nsrssltrust:

cd /opt/nre/java/latest/bin
./keytool -import -alias emcauthctomcat -keystore /opt/nsr/authc-server/conf/authc.truststore -storepass 'authc-password" -file certificate_file.cer
./keytool -import -alias emcauthctomcat -keystore/opt/nre/java/latest/lib/security/cacerts-storepass changeit -file certificate_file.cer

Exempel: 
root@NWrhelNodeF:/opt/nre/java/latest/bin# ./keytool -import -alias emcauthctomcat -keystore /opt/nsr/authc-server/conf/authc.truststore -storepass 'authc-password' -file /root/emcauthctomcat.cer

Certificate already exists in keystore under alias <emcnwuiserv>
Do you still want to add it? [no]:  yes
Certificate was added to keystore
 

Test:

För att validera att certifikaten nu är giltiga växlar du klustret till noden genom att tillämpa ovanstående ändringar på:

1. Kommandona authc_mgmt eller authc_config bör nu fungera på den nod de tidigare misslyckades med:

root@NWrhelNodeF:~# authc_mgmt -u Administrator -p 'NetWorker_Admin_password' -e find-all-users
The query returns 1 records.
User Id User Name
1000    administrator

2. För ytterligare verifiering kan vi se att certifikaten överensstämmer från både lokala och delade platser:

Om AUTHC/NMC-servern är ett centralt fristående NetWorker-system påverkar inte problemet NetWorker Management Console (NMC), NetWorker-webbanvändargränssnittet (NWUI) eller REST API-begäranden.
