System users and valid shells...



Hi,

this may be a dumb question, but I really wonder if there's a policy
(which I obviously haven't found) about which system users should get
a valid shell and which shouldn't.

I get tons of warnings like this when I run tiger(8):

NEW: --WARN-- [pass014w] Login (bin) is disabled, but has a valid shell.
NEW: --WARN-- [pass014w] Login (daemon) is disabled, but has a valid shell.
NEW: --WARN-- [pass014w] Login (games) is disabled, but has a valid shell.
NEW: --WARN-- [pass014w] Login (gnats) is disabled, but has a valid shell.
NEW: --WARN-- [pass014w] Login (irc) is disabled, but has a valid shell.
NEW: --WARN-- [pass014w] Login (lp) is disabled, but has a valid shell.
NEW: --WARN-- [pass014w] Login (mail) is disabled, but has a valid shell.
NEW: --WARN-- [pass014w] Login (man) is disabled, but has a valid shell.
NEW: --WARN-- [pass014w] Login (news) is disabled, but has a valid shell.
NEW: --WARN-- [pass014w] Login (operator) is disabled, but has a valid shell.
NEW: --WARN-- [pass014w] Login (postgres) is disabled, but has a valid shell.
NEW: --WARN-- [pass014w] Login (proxy) is disabled, but has a valid shell.
NEW: --WARN-- [pass014w] Login (sys) is disabled, but has a valid shell.
NEW: --WARN-- [pass014w] Login (uucp) is disabled, but has a valid shell.
NEW: --WARN-- [pass014w] Login (www-data) is disabled, but has a valid shell.
[...]

Security-wise it's probably a good idea to give as few users as possible
a valid shell, all others should get /bin/false, right?

Should I CC debian-security?

Uwe.
