source: openpam/trunk/lib/openpam_set_feature.c @ 594

Last change on this file since 594 was 594, checked in by Dag-Erling Smørgrav, 9 years ago

Add an experimental mechanism for enabling / disabling optional features.
Use it to control policy and module file checks. The default settings
correspond to the current behavior: disallow path separators in policy
names, but allow them in module names; verify ownership and permissions
for both policy files and modules.
