Well, back in the Old Days, you could do this with the NetInfo
framework. Today, you could use NSTask to execute "nidump passwd
.", which will give you something like this:
Using NetInfo is not recommended for these kinds of Queries any more.
The recommended way is to use DirectoryServices, which gives you the
same results in a different manner. For example, use dscl instead of
nicl.
nobody:*:-2:-2::0:0:Unprivileged User:/var/empty:/usr/bin/false
root:*:0:0::0:0:System Administrator:/var/root:/bin/sh
...
[snippage. You get the idea.]
...
securityagent:*:92:92::0:0:SecurityAgent:/var/empty:/usr/bin/false
jcr:********:501:501::0:0:John C. Randolph:/Users/jcr:/bin/bash
foo:********:502:502::0:0:foo:/Users/foo:/bin/bash
Any UIDs less than 500 are probably not real users, unless someone's
decided to go against the guidelines in Apple's sysadmin docs.
Not best to use that logic. Since you've got root and uids can be
arbitrary. The best test (in my experience) is to see if the user has
a valid shell. See your above dump, /usr/bin/false is not a valid
shell so the user is not "valid". You cannot trust the home folder
test as many default users have valid home folders.
