Create a home directory for each user that will connect to the i5/OS™ applications.
After you have added the i5/OS principal to the Kerberos server, you need to create a /home directory for each user that will connect to the i5/OS applications. This directory will contain a file that contains the name of the user's Kerberos credentials cache. Each user should either be the owner of his directory or have the appropriate authority to create files within his directory.
