In your SOPW query, you seem open to "some other method?". So, below I will demo another possible technique for you using SQlite + some Perl code. The DB is good at figuring out unique combinations of columns. Below, I did that for 2 columns. Then for each of the combinations, I got the logons associated with them. I did not fiddle with the inherited column. But other than that, this produces the desired output that you listed.

It sounds like you are working a large dataset. Using a DB could be much more flexible than some complex Perl hash of hash code. I wanted to make you aware of this possibility.
