You need to create a directory in the /home directory to store your Kerberos credentials cache. To create a home directory, complete the following:
On a command line, enter: CRTDIR '/home/user profile' where user profile is your i5/OS™ user profile name. For example: CRTDIR '/home/JOHND'.
Now that you have created the home directory, you can verify that network authentication service is configured correctly.
