PAM_ACCESS(8) Linux-PAM Manual PAM_ACCESS(8)NAMEpam_access - PAM module for logdaemon style login access control
SYNOPSIS
pam_access.so [debug] [noaudit] [accessfile=file] [fieldsep=sep]
[listsep=sep]
DESCRIPTION
The pam_access PAM module is mainly for access management. It provides
logdaemon style login access control based on login names, host or
domain names, internet addresses or network numbers, or on terminal
line names in case of non-networked logins.
By default rules for access management are taken from config file
/etc/security/access.conf if you don't specify another file.
OPTIONS
accessfile=/path/to/access.conf
Indicate an alternative access.conf style configuration file to
override the default. This can be useful when different services
need different access lists.
debug A lot of debug informations are printed with syslog(3).
noaudit
Do not report logins from disallowed hosts and ttys to the audit
subsystem.
fieldsep=separators
This option modifies the field separator character that
pam_access will recognize when parsing the access configuration
file. For example: fieldsep=| will cause the default `:'
character to be treated as part of a field value and `|' becomes
the field separator. Doing this may be useful in conjuction with
a system that wants to use pam_access with X based applications,
since the PAM_TTY item is likely to be of the form "hostname:0"
which includes a `:' character in its value. But you should not
need this.
listsep=separators
This option modifies the list separator character that
pam_access will recognize when parsing the access configuration
file. For example: listsep=, will cause the default ` ' (space)
and `\t' (tab) characters to be treated as part of a list
element value and `,' becomes the only list element separator.
Doing this may be useful on a system with group information
obtained from a Windows domain, where the default built-in
groups "Domain Users", "Domain Admins" contain a space.
