[Samba] specifying groups: @ vs. +

[Thomas Limoncelli]

In *non-NIS* environments: is there *any* difference in specifying 
@mygroup vs. +mygroup in smb.conf?

smb.conf(5) from 3.0.21c says:

   A  name  starting with a '@' is interpreted as an NIS net-
   group first (if your system supports NIS), and then  as  a
   UNIX  group  if the name was not found in the NIS netgroup
   database.

   A name starting with '+' is interpreted only by looking in
   the  UNIX  group  database.

which suggests that they should work equally in non-NIS environments. 
Still, to double-check: is there any (even slight) overhead imposed by 
one vs. the other?
