3 rlm_unix \- FreeRADIUS Module
5 The \fIrlm_unix\fP module allows authentication against the system
6 password, shadow, and group files. It also provides FreeRADIUS an
7 interface into a radwtmp file (used by "radlast") when added to the
10 The \fIrlm_unix\fP module provides the functionality for "Auth-Type =
11 System", rather than "Auth-Type = Unix". The "System" name is used
12 for historical reasons.
14 The main configuration items to be aware of are:
16 This is a 'yes' or 'no' option. If set to yes, FreeRADIUS will read
17 the system files into memory, rather than perform a system call to
18 lookup the information. On *BSD systems, you should set this value to
19 no. On other systems, if you have a very large passwd and shadow
20 files, you can try setting this to yes, which may increase the servers
21 performance. The default is no.
23 This is the number of seconds to wait between refreshing the cached
24 files from the system. It has no effect unless you enable caching.
26 The path to the system passwd file. Usually /etc/passwd. If
27 commented out, or not set, the server will retrieve the information
30 The path to the system shadow file. Usually /etc/shadow. This is not
33 The path to the system group file. Usually /etc/group. This is not
36 The path to the system wtmp file to be used for keeping the database
37 of online users as read by the 'radlast' program.
39 This is a 'yes' or 'no' option. If set to 'yes' this allows the Group
40 attribute to be used as a check item. Default is 'no'.
