NAMEpam_access - PAM module for logdaemon style login access control
SYNOPSISpam_access.so [debug] [nodefgroup] [noaudit] [accessfile=file] [fieldsep=sep] [listsep=sep]
DESCRIPTIONThe 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. If Linux PAM is compiled with audit support the module will report when it denies access based on origin (host or tty).
OPTIONSaccessfile=/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 information is 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 conjunction 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. nodefgroup 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.
MODULE TYPES PROVIDEDAll module types (auth, account, password and session) are provided.
RETURN VALUESPAM_SUCCESS Access was granted. PAM_PERM_DENIED Access was not granted. PAM_IGNORE pam_setcred was called which does nothing. PAM_ABORT Not all relevant data or options could be gotten. PAM_USER_UNKNOWN The user is not known to the system.
FILES/etc/security/access.conf Default configuration file
