NAME

       pam_list - PAM account management module for UNIX

SYNOPSIS

	pam_list.so.1

DESCRIPTION

       The  pam_list module implements pam_sm_acct_mgmt(3PAM), which provides  functionality to the PAM account management stack.  The module pro-
       vides functions to validate  that  the  user's account  is  valid on this host based on a list of users and/or netgroups in the given file.
       The users and netgroups are separated by newline character. Netgroups are specified with character '@' as prefix before name of netgroup in
       the list. The maximum line lenght is 1023 characters.

       The username is the value of PAM_USER. The host is the value of PAM_RHOST or, if PAM_RHOST is not  set,	the  value  of	the  localhost	as
       returned by gethostname(3C) is used.

       If  neither  of	the  allow, deny, or compat options are specified, the module will look for +/- entries in the local /etc/passwd file.	If
       this style is used, nsswitch.conf(4) must not be configured with compat for the passwd database. If no relevant +/- entry  exists  for  the
       user, pam_list is not participating in result.

       If  compat  option is specified then the module will look for +/- entries in the local /etc/passwd file. Other entries in this file will be
       counted as + entries. If no relevant entry exits for the user, pam_list will deny the access.

       The following options can be passed to the module:

       allow=		  The full pathname to a file of allowed users and/or netgroups. Only one of allow= or deny= can be specified.

       compat		  Activate compat mode.

       deny=		  The full pathname to a file of denied users and/or netgroups. Only one of deny= or allow= can be specified.

       debug		  Provide syslog(3C) debugging information at the LOG_AUTH | LOG_DEBUG level.

       user		  The module should only perform netgroup matches on the username. This is the default option.

       nouser		  The username should not be used in the netgroup match.

       host		  Only the host should be used in netgroup matches.

       nohost		  The hostname should not be used in netgroup matches.

       user_host_exact	  The user and hostname must be in the same netgroup.

ERRORS

       The following error values are returned:

       PAM_SERVICE_ERR	   An invalid set of module options was given in the pam.conf(4) for this module, or the user/netgroup file could  not	be
			   opened.

       PAM_BUF_ERR	   A memory buffer error occurred.

       PAM_IGNORE	   The module is ignored, as it is not participating in the result.

       PAM_PERM_DENIED	   The user is not on the allow list or is on the deny list.

       PAM_SUCCESS	   The account is valid for use at this time.

       PAM_USER_UNKNOWN    No account is present for the user

EXAMPLES

       In the case of default mode or compat mode, the important lines in /etc/passwd appear as follows:

	 +loginname	- user is approved
	 -loginname	- user is disapproved
	 +@netgroup	- netgroup members are approved
	 -@netgroup	- netgroup members are disapproved

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       +-----------------------------+-----------------------------+
       |Interface Stability	     |Committed 		   |
       +-----------------------------+-----------------------------+
       |MT-Level		     |MT-Safe with exceptions	   |
       +-----------------------------+-----------------------------+

       The interfaces in libpam(3LIB) are MT-Safe only if each thread within the multithreaded application uses its own PAM handle.
