 Title: #78: ipa: Nested netgroups do not work
Action: opened

PR body:
"""
We lowercase the keys to the hash table used to store netgroups
but do not lowercase it when reading the table. This results
in nested netgroups not being found when they should and
the processing fails.

The lowercasing does not seem to be necessary anymore (not
sure if it ever was) so we can skip it.

Resolves:
