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\&. +.PP +By default rules for access management are taken from config file +\FC/etc/security/access\&.conf\F[] +if you don\'t specify another file\&. +.PP +If Linux PAM is compiled with audit support the module will report when it denies access based on origin (host or tty)\&. +.SH "OPTIONS" +.PP +\fBaccessfile=\fR\fB\fI/path/to/access\&.conf\fR\fR +.RS 4 +Indicate an alternative +\FCaccess\&.conf\F[] +style configuration file to override the default\&. This can be useful when different services need different access lists\&. +.RE +.PP +\fBdebug\fR +.RS 4 +A lot of debug information is printed with +\fBsyslog\fR(3)\&. +.RE +.PP +\fBnoaudit\fR +.RS 4 +Do not report logins from disallowed hosts and ttys to the audit subsystem\&. +.RE +.PP +\fBfieldsep=\fR\fB\fIseparators\fR\fR +.RS 4 +This option modifies the field separator character that pam_access will recognize when parsing the access configuration file\&. For example: +\fBfieldsep=|\fR +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 conjunction with a system that wants to use pam_access with X based applications, since the +\fBPAM_TTY\fR +item is likely to be of the form "hostname:0" which includes a `:\' character in its value\&. But you should not need this\&. +.RE +.PP +\fBlistsep=\fR\fB\fIseparators\fR\fR +.RS 4 +This option modifies the list separator character that pam_access will recognize when parsing the access configuration file\&. For example: +\fBlistsep=,\fR +will cause the default ` \' (space) and `\et\' (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\&. +.RE +.PP +\fBnodefgroup\fR +.RS 4 +User tokens which are not enclosed in parentheses will not be matched against the group database\&. The backwards compatible default is to try the group database match even for tokens not enclosed in parentheses\&. +.RE +.SH "MODULE TYPES PROVIDED" +.PP +All module types (\fBauth\fR, +\fBaccount\fR, +\fBpassword\fR +and +\fBsession\fR) are provided\&. +.SH "RETURN VALUES" +.PP +PAM_SUCCESS +.RS 4 +Access was granted\&. +.RE +.PP +PAM_PERM_DENIED +.RS 4 +Access was not granted\&. +.RE +.PP +PAM_IGNORE +.RS 4 + +\fBpam_setcred\fR +was called which does nothing\&. +.RE +.PP +PAM_ABORT +.RS 4 +Not all relevant data or options could be gotten\&. +.RE +.PP +PAM_USER_UNKNOWN +.RS 4 +The user is not known to the system\&. +.RE +.SH "FILES" +.PP +\FC/etc/security/access\&.conf\F[] +.RS 4 +Default configuration file +.RE +.SH "SEE ALSO" +.PP + +\fBaccess.conf\fR(5), +\fBpam.d\fR(5), +\fBpam\fR(8)\&. +.SH "AUTHORS" +.PP +The logdaemon style login access control scheme was designed and implemented by Wietse Venema\&. The pam_access PAM module was developed by Alexei Nogin <alexei@nogin\&.dnttm\&.ru>\&. The IPv6 support and the network(address) / netmask feature was developed and provided by Mike Becher <mike\&.becher@lrz\-muenchen\&.de>\&. |
