Examine All Information Source Files

Check all /etc files and NIS maps for empty fields or corrupted data before configuring NIS+. The NIS+ table-populating scripts and commands might not succeed if the data source files contain empty fields or extraneous characters. Fill blank fields or fix the data before you start. It is better to delete questionable users or machines from the /etc files or NIS maps before running NIS+ scripts, then add them back later after NIS+ is installed, than to proceed with the scripts and possibly corrupt data.
