NAME

     pam_tacplus -- TACACS+ authentication PAM module

SYNOPSIS

     [service-name] module-type control-flag pam_tacplus [options]

DESCRIPTION

     The pam_tacplus module provides authentication services based upon the TACACS+ protocol for the PAM (Pluggable Authentication Module) frame-
     work.

     The pam_tacplus module accepts these optional parameters:

     use_first_pass  causes pam_tacplus to use a previously entered password instead of prompting for a new one.  If no password has been entered
		     then authentication fails.

     try_first_pass  causes pam_tacplus to use a previously entered password, if one is available.  If no password has been entered, pam_tacplus
		     prompts for one as usual.

     echo_pass	     causes echoing to be left on if pam_tacplus prompts for a password.

     conf=pathname   specifies a non-standard location for the TACACS+ client configuration file (normally located in /etc/tacplus.conf).

     template_user=username
		     specifies a user whose passwd(5) entry will be used as a template to create the session environment if the supplied username
		     does not exist in local password database.  The user will be authenticated with the supplied username and password, but his
		     credentials to the system will be presented as the ones for username, i.e., his login class, home directory, resource limits,
		     etc. will be set to ones defined for username.

		     If this option is omitted, and there is no username in the system databases equal to the supplied one (as determined by call
		     to getpwnam(3)), the authentication will fail.

NAME

     pam_unix -- UNIX PAM module

SYNOPSIS

     [service-name] module-type control-flag pam_unix [options]

DESCRIPTION

     The UNIX authentication service module for PAM provides functionality for two PAM categories: authentication and account management.  In
     terms of the module-type parameter, they are the ``auth'' and ``account'' features.  It also provides a null function for session management.

   UNIX Authentication Module
     The UNIX authentication component provides functions to verify the identity of a user (pam_sm_authenticate()), which obtains the relevant
     passwd(5) entry.  It prompts the user for a password and verifies that this is correct with crypt(3).

     The following options may be passed to the authentication module:

     debug	     syslog(3) debugging information at LOG_DEBUG level.

     use_first_pass  If the authentication module is not the first in the stack, and a previous module obtained the user's password, that password
		     is used to authenticate the user.	If this fails, the authentication module returns failure without prompting the user for a
		     password.	This option has no effect if the authentication module is the first in the stack, or if no previous modules
		     obtained the user's password.

     try_first_pass  This option is similar to the use_first_pass option, except that if the previously obtained password fails, the user is
		     prompted for another password.

     auth_as_self    This option will require the user to authenticate himself as the user given by getlogin(2), not as the account they are
		     attempting to access.  This is primarily for services like su(1), where the user's ability to retype their own password might
		     be deemed sufficient.

     nullok	     If the password database has no password for the entity being authenticated, then this option will forgo password prompting,
		     and silently allow authentication to succeed.

   UNIX Account Management Module
     The UNIX account management component provides a function to perform account management, pam_sm_acct_mgmt().  The function verifies that the
     authenticated user is allowed to login to the local user account by checking the password expiry date.

     The following options may be passed to the management module:

     debug	     syslog(3) debugging information at LOG_DEBUG level.

   UNIX Password Management Module
     The UNIX password management component provides a function to perform account management, pam_sm_chauthtok().  The function changes the
     user's password.

     The following options may be passed to the password module:

     debug	     syslog(3) debugging information at LOG_DEBUG level.

     no_warn	     suppress warning messages to the user.  These messages include reasons why the user's authentication attempt was declined.

     passwd_db=name  Change the user's password only the specified password database.  Valid password database names are:

		     files  local password file

		     nis    NIS password database

FILES

     /etc/master.passwd  default UNIX password database.
