Solution:

To do so, set up the kerberos server and follow the below steps:

1. Create keytab file for Artifactory user on KDC server:

​​$ ktutil 
ktutil:  add_entry -password -p artifactory@test.ca -k 1 -e aes256-cts-hmac-sha1-96
ktutil:  wkt artifactory.keytab
ktutil:  exit

2. Copy artifactory.keytab to the location readable by Artifactory. In this example, I will use /var/opt/jfrog/artifactory/etc/artifactory.keytab. Change ownership of file to artifactory user.

3. log in as artifactory user:  su -s /bin/bash artifactory

4. Run: kinit artifactory

5. Add below java parameters as seen here:

• Dsun.security.krb5.debug=true -Djavax.security.auth.useSubjectCredsOnly=false -Djava.security.auth.login.config=/var/opt/jfrog/artifactory/jaas.conf -Dsun.security.jgss.native=true

6. Configure Artifactory:

• For 6.x in $ARTIFACTORY_HOME/etc/db.properties:

"jdbc:postgresql://pg.test.ca:5432/artifactory?gssEncMode=require&loggerLevel=TRACE&loggerFile=/var/opt/jfrog/artifactory/pgjdbc-trace.log"

• For 7.x in $JFROG_HOME/var/etc/system.yaml (Versions 7.39.x and above):

shared:
    database:
        type: postgresql
        driver: org.postgresql.Driver
        url: "jdbc:postgresql://pg.test.ca:5432/artifactory?gssEncMode=require&loggerLevel=TRACE&loggerFile=/var/opt/jfrog/artifactory/log/pgjdbc-trace.log"
        username: artifactory
        password: password
        kerberosAuth: true

7.  Create

 /var/opt/jfrog/artifactory/jaas.conf owned by artifactory user:

pgjdbc {
com.sun.security.auth.module.Krb5LoginModule required
doNotPrompt=true
useTicketCache=true
renewTGT=true
debug=true
useKeyTab=true
keyTab="/var/opt/jfrog/artifactory/etc/artifactory.keytab"
principal="artifactory@TEST.CA";
};
