Step 2. Set up the Cross-Realm Trust

Step 2. Set up the Cross-Realm Trust

Perform this step when the Informatica domain uses Kerberos authentication.
Set up a one-way cross-realm trust to enable the KDC for the MIT Kerberos server to communicate with the KDC for the Active Directory server. When you set up the one-way cross-realm trust, the Hadoop cluster can authenticate the Active Directory principals.
To set up the cross-realm trust, you must complete the following steps:
  1. Configure the Active Directory server to add the local MIT realm trust.
  2. Configure the MIT server to add the cross-realm principal.
  3. Translate principal names from the Active Directory realm to the MIT realm.
