Interaction with +/- syntax
Releases prior to SunOS 5.0 did not have the name service
switch but did allow the user some policy control. In
/etc/passwd one could have entries of the form +user
(include the specified user from NIS passwd.byname), -user
(exclude the specified user) and + (include everything,
except excluded users, from NIS passwd.byname). The desired
behavior was often "everything in the file followed by
everything in NIS", expressed by a solitary + at the end of
/etc/passwd. The switch provides an alternative for this
case ("passwd: files nis") that does not require + entries
in /etc/passwd and /etc/shadow (the latter is a new addition
to SunOS 5.0, see shadow(4)).
If this is not sufficient, the NIS/YP compatibility source
provides full +/- semantics. It reads /etc/passwd for
getpwnam(3C) functions and /etc/shadow for getspnam(3C)
functions and, if it finds +/- entries, invokes an appropri-
ate source. By default, the source is "nis", but this may be
overridden by specifying "nisplus" or "ldap" as the source
for the pseudo-database passwd_compat.
Note that in compat mode, for every /etc/passwd entry, there
must be a corresponding entry in the /etc/shadow file.

The NIS/YP compatibility source also provides full +/-
semantics for group; the relevant pseudo-database is
group_compat.

mais je n'oserais pas...
pour ma part, je n'utilise que les lignes
passwd: compat
group: compat
shadow: compat
aussi bien sur solaris que linux depuis siuffisamment longtemps pour
avoir oublie la raison
