1 This is nss_nonlocal, an nsswitch module that acts as a proxy for other
2 nsswitch modules like hesiod, but prevents non-local users from
3 potentially gaining local privileges by spoofing local UIDs and GIDs.
5 To use it, configure /etc/nsswitch.conf as follows:
7 passwd: compat nonlocal
8 passwd_nonlocal: hesiod
10 group_nonlocal: hesiod
