NetWorker: klusteroitujen RHEL-palvelinten authc-komennot ilmoittavat, että pyydettyyn kohteeseen ei löydy kelvollista sertifiointipolkua.

Summary: NetWorker on asennettu RHEL/CentOS Linux -klusteriin High Availability -toiminnolla. Kun authc-määrityksen komentoja (authc_config, authc_mgmt) suoritetaan, komento palauttaa virheilmoituksen Unable to find valid certification path to requested target. ...

Symptoms

  • NetWorker-palvelimen käyttöönotto määritetään RHEL-/CentOS 7.x- tai 8.x Linux -palvelimissa High Availability -klusteroinnin avulla. 
  • authc_config ja authc_mgmt-komennot palauttavat varmennepolkuvirheen:

HUOMAUTUS: Määritä authc-avainsäilön salasana -storepass-arvolle. Authc-avainsyöttimen salasana määritetään alkumäärityksen aikana, kun kussakin solmussa suoritetaan komentosarja /opt/nsr/authc-server/scripts/authc_configure.sh.
  • Varmennepolun virhettä ei havaita solmussa, jossa kaikki varmenteet vastaavat toisiaan:
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

Ennen kuin NetWorker-palvelimet lisätään klusteriin käyttäen /usr/sbin/networker.cluster-klusteria, ne määritetään erillisiksi palvelimille. /opt/nsr/authc-server/scripts/authc_configure.sh suoritetaan asennuksen jälkeen, ja solmukohtaisia yksilöiviä varmenteita luodaan. Jaetussa sijainnissa käytetyt varmenteet vastaavat solmun aktiivista solmua, jossa klusteroitu nws-resurssi käynnistettiin. 
 

/nsr-hakemisto linkitetään symbolisesti /nsr_share/nsr-hakemistoon, joka siirretään solmujen välillä sen mukaan, kumpi solmu on nykyinen aktiivinen solmu. /opt/nsr/authc-server/conf/authc.truststore on kunkin solmun paikallinen ja sitä ei jaeta vikasiedon yhteydessä. Solmun vikasiedon jälkeen /nsr/authc/conf/authc.keystore emcauthc -varmenteiden allekirjoitukset täsmäävät valitsimen /opt/nsr kanssa. alkuperäisen solmun varmenteet, mutta ei nykyisen aktiivisen solmun. 

Resolution

Ratkaisu:

Ongelma on korjattu seuraavissa NetWorker-versioissa:
  • 19.8.0.4
  • 19.9.0.2
Päivitä johonkin luetelluista NetWorker-versioista (tai uudempaan). NetWorker-paketteja voi ladata seuraavasta osoitteesta: https://www.dell.com/support/home/product-support/product/networker/drivers
 
HUOMAUTUS: Kun NetWorker on päivitetty ja klusteroitu nws-resurssi on otettu käyttöön, sinun on suoritettava uudelleen /opt/nsr/authc-server/scripts/authc_configure.sh solmussa, jossa varmenneristiriita havaittiin. Tämä korjaa ristiriidan.

For optimum security, EMC NetWorker Authentication Service will
use a non-root user (nsrtomcat) to start the Apache Tomcat instance.
If your system has special user security requirements, ensure that proper
operational permissions are granted to this non-root user (nsrtomcat).
Please refer to NetWorker Installation Guide.

Do you wish to specify a different port number [y]? n
The Apache Tomcat will use "lnx-node1.amer.lan" as the host name.
The Apache Tomcat will use "9090" as the port number.
The NetWorker Authentication Service requires a keystore file to configure encryption and to provide SSL support.
EMC recommends that you specify a keystore password that has a minimum of six characters.
Do you want to use the existing keystore /nsr/authc/conf/authc.keystore [y]?
Specify password for the existing keystore:
The install will use the existing certificate "emcauthctomcat" for Apache Tomcat.
The install will use the existing certificate "emcauthcsaml" for Authentication Service.
The NetWorker Authentication Service defines automatically an administrator user account

Kiertotapa:

1. Luo solmu, jossa varmenteet vastaavat pc-tietokoneiden aktiivista solmua. Esimerkkejä ongelman määrittämisestä on Symptoms-kentässä. 
2. Kirjaudu passiiviseen solmuun (jossa varmenteet eivät täsmää). 
3. Luo varmennetiedosto virtuaaliklusteriresurssille nsrssltrust-komennolla : 

nsrssltrust -u https:// cluster-hostname:9090 -c certificate_file.cer

Esimerkki:

root@NWrhelNodeF:~# nsrssltrust -u https://NWrhelClusD.emclab.local:9090 -c emcauthctomcat.cer
Fetching server's CA certificate chain / server certificate (if CA is not available)...

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

4. Varmista, että luodun varmenteen allekirjoitus vastaa aktiivisen solmun jaetun varmenteen allekirjoitusta:

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

Esimerkki:

root@NWrhelNodeF:/opt/nre/java/latest/bin# ./keytool -printcert -file /root/emcauthctomcat.cer | grep SHA256

5. Poista paikalliset emcauthctomcat-varmenteet authc.truststore- ja cacerts-tiedostosta solmussa, jonka varmenteet eivät täsmää.

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'

HUOMAUTUS: Jos toiminto onnistuu, tuloksia ei palauteta.

6. Tuo nsrssltrustilla luotu varmenne:

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

Testi:

Varmenteiden kelvollisuus voidaan varmistaa kytkemällä klusteri vikasietosolmuun, johon edellä mainitut muutokset otettiin käyttöön:

1. authc_mgmt- tai authc_config-komentojen pitäisi nyt toimia solmussa, jossa ne ovat aikaisemmin epäonnistuneet:

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. Lisävarmennetta varten on nähtävissä, että varmenteet vastaavat sekä paikallisia että jaettuja sijainteja:

root@NWrhelNodeF:/opt/nre/java/latest/bin# ./keytool -list -keystore /nsr_share/nsr/authc/conf/authc.keystore -storepass 'authc-password' | grep -A1 emcauthctomcat

Additional Information

Jos AUTHC-/NMC-palvelin on itsenäinen NetWorker-järjestelmä, tämä ongelma ei vaikuta NMC (NetWorker Management Console),NetWorker-verkkokäyttöliittymään (NWUI) eikä REST API -pyyntöihin.
