RE: Unix authorities

Phil,

Execute authority to a directory allows you to search that directory,
execute authority to a library allows you to search that library. You still
need authority to the objects you find in the directory or library to do
anything with them.

I recommend that you read the first few pages of Appendix D of the Security
Reference manual for a better understanding of how *R, *RW, and *X are
implemented on the iSeries. This URL should take you to that book:

hierarchy.
