6 <para>This is a list of users that should not be allowed
7 to login to this service. This is really a <emphasis>paranoid</emphasis>
8 check to absolutely ensure an improper setting does not breach
11 <para>A name starting with a '@' is interpreted as an NIS
12 netgroup first (if your system supports NIS), and then as a UNIX
13 group if the name was not found in the NIS netgroup database.</para>
15 <para>A name starting with '+' is interpreted only
16 by looking in the UNIX group database via the NSS getgrnam() interface. A name starting with
17 '&' is interpreted only by looking in the NIS netgroup database
18 (this requires NIS to be working on your system). The characters
19 '+' and '&' may be used at the start of the name in either order
20 so the value <parameter moreinfo="none">+&group</parameter> means check the
21 UNIX group database, followed by the NIS netgroup database, and
22 the value <parameter moreinfo="none">&+group</parameter> means check the NIS
23 netgroup database, followed by the UNIX group database (the
24 same as the '@' prefix).</para>
26 <para>The current servicename is substituted for <parameter moreinfo="none">%S</parameter>.
