NAME

6       pam_access - PAM module for logdaemon style login access control
7

SYNOPSIS

9       pam_access.so [debug] [accessfile=file] [fieldsep=sep] [listsep=sep]
10

DESCRIPTION

12       The pam_access PAM module is mainly for access management. It provides
13       logdaemon style login access control based on login names, host or
14       domain names, internet addresses or network numbers, or on terminal
15       line names in case of non-networked logins.
16
17       By default rules for access management are taken from config file
18       /etc/security/access.conf if you don't specify another file.
19

OPTIONS

21       accessfile=/path/to/access.conf
22          Indicate an alternative access.conf style configuration file to
23          override the default. This can be useful when different services
24          need different access lists.
25
26       debug
27          A lot of debug informations are printed with syslog(3).
28
29       fieldsep=separators
30          This option modifies the field separator character that pam_access
31          will recognize when parsing the access configuration file. For
32          example: fieldsep=| will cause the default `:' character to be
33          treated as part of a field value and `|' becomes the field
34          separator. Doing this may be useful in conjuction with a system that
35          wants to use pam_access with X based applications, since the PAM_TTY
36          item is likely to be of the form "hostname:0" which includes a `:'
37          character in its value. But you should not need this.
38
39       listsep=separators
40          This option modifies the list separator character that pam_access
41          will recognize when parsing the access configuration file. For
42          example: listsep=, will cause the default ` ' (space) and `\t' (tab)
43          characters to be treated as part of a list element value and `,'
44          becomes the only list element separator. Doing this may be useful on
45          a system with group information obtained from a Windows domain,
46          where the default built-in groups "Domain Users", "Domain Admins"
47          contain a space.
