Details:
Suppose there exists a local group (in /etc/group) "users" with gid 100 and
an NIS group of the same name but gid 200. Suppose that /etc/nsswitch.conf
has
group: files nis
Then command #1 below will show files with either gid 100 or gid 200 as
having group "users", but command #2 will show only those files with gid 100
(e.g. none, if they all have gid 200):
#1 find . -ls
#2 find . -group users
The problem may be more general; it may affect duplicate names wherever they
occur and affect usernames as well as groups. There may be a similar problem
for duplicate ids with different names.
The problem could be addressed by building a complete map of ids vs. names,
or at least flagged by doing reverse-lookups (e.g. both getgrnam() and
getgrgid()).
