Steps to make Kerberos authentication work with active directory
Ensure that krb5-workstation or krb5-server is installed on both PostgreSQL client and server machines. If not, get it installed.
PostgreSQL DB server setup (pgdbserver.myenterprise.net)
5. After copying the keytab file to the database server (pgdbserver.myenterprise.net), verify the contents of keytab with the ktutil command.
PostgreSQL client setup (pgclient.myenterprise.net)
9. Ensure that Steps 1, 2 and 3 above were followed on client machine.
What port is used for Kerberos authentication?
