NAME

     pam_duo -- PAM module for Duo authentication

SYNOPSIS

     pam_duo.so [conf=<FILENAME>]

DESCRIPTION

     pam_duo provides secondary authentication (typically after successful password-based authentication) through the Duo authentication service.

OPTIONS

     PAM module configuration options supported:

     conf      Specify an alternate configuration file to load. Default is /etc/duo/pam_duo.conf

     debug     Debug mode; send log messages to stderr instead of syslog.

CONFIGURATION

     The INI-format configuration file must have a ``duo'' section with the following options:

     host      Duo API host (required).

     ikey      Duo integration key (required).

     skey      Duo secret key (required).

     groups    If specified, Duo authentication is required only for users whose primary group or supplementary group list matches one of the
	       space-separated pattern-lists (see PATTERNS below).

     failmode  On service or configuration errors that prevent Duo authentication, fail ``safe'' (allow access) or ``secure'' (deny access).
	       Default is ``safe''.

     pushinfo  Send command to be approved via Duo Push authentication. Default is ``no''.

     An example configuration file:

	     [duo]
	     host = api-deadbeef.duosecurity.com
	     ikey = SI9F...53RI
	     skey = 4MjR...Q2NmRiM2Q1Y
	     pushinfo = yes

     Other authentication restrictions may be implemented using pam_listfile(8), pam_access(8), etc.

PATTERNS

     A pattern consists of zero or more non-whitespace characters, '*' (a wildcard that matches zero or more characters), or '?' (a wildcard that
     matches exactly one character).

     A pattern-list is a comma-separated list of patterns. Patterns within pattern-lists may be negated by preceding them with an exclamation mark
     ('!').  For example, to specify Duo authentication for all users (except those that are also admins), and for guests:

	   groups = users,!wheel,!*admin guests

FILES

     /etc/duo/pam_duo.conf
	       Default configuration file path

AUTHORS

     pam_duo was written by Duo Security <duo_unix@duosecurity.com>

NOTES

     When used with OpenSSH's sshd(8), only PAM-based authentication can be protected with this module; pubkey authentication bypasses PAM
     entirely. OpenSSH's PAM integration also does not honor an interactive pam_conv(3) conversation, prohibiting real-time Duo status messages
     (such as during voice callback).

NAME

       pam_ldap - PAM module for LDAP-based authentication

SYNOPSIS

       pam_ldap.so [...]

DESCRIPTION

       This is a PAM module that uses an LDAP server to verify user access rights and credentials.

OPTIONS

       use_first_pass
	      Specifies that the PAM module should use the first password provided in the authentication stack and not prompt the user for a pass-
	      word.

       try_first_pass
	      Specifies that the PAM module should use the first password provided in the authentication stack and if that fails prompt  the  user
	      for a password.

       nullok Specifying this option allows users to log in with a blank password.  Normally logins without a password are denied.

       ignore_unknown_user
	      Specifies  that  the  PAM module should return PAM_IGNORE for users that are not present in the LDAP directory.  This causes the PAM
	      framework to ignore this module.

       ignore_authinfo_unavail
	      Specifies that the PAM module should return PAM_IGNORE if it cannot contact the LDAP server.  This causes the PAM framework  to  ig-
	      nore this module.

       no_warn
	      Specifies that warning messages should not be propagated to the PAM application.

       use_authtok
	      This  causes the PAM module to use the earlier provided password when changing the password. The module will not prompt the user for
	      a new password (it is analogous to use_first_pass).

       debug  This option causes the PAM module to log debugging information to syslog(3).

       minimum_uid=UID
	      This option causes the PAM module to ignore the user if the user id is lower than the specified value. This can be  used	to  bypass
	      LDAP checks for system users (e.g. by setting it to 1000).

MODULE SERVICES PROVIDED

       All services are provided by this module but currently sessions changes are not implemented in the nslcd daemon.

FILES

       /etc/pam.conf
	      the main PAM configuration file

       /etc/nslcd.conf
	      The configuration file for the nslcd daemon (see nslcd.conf(5))
