Kerberos keytab file content may be visible.
keytab is similar to a private key file and should not be readable.
Import a Kerberos keytab file. From the command line, check the file permissions. It is readable.
Use chmod to change the keytab file permission manually so that it is not world-readable.
Kerberos keytab file content is now protected with appropriate security permissions.
