pam_ssh_agent_auth

pam_ssh_agent_auth(8)							PAM						     pam_ssh_agent_auth(8)

PAM_SSH_AGENT_AUTH
       This module provides authentication via ssh-agent.  If an ssh-agent listening at SSH_AUTH_SOCK can successfully authenticate that it has
       the secret key for a public key in the specified file, authentication is granted, otherwise authentication fails.

SUMMARY

       /etc/pam.d/sudo: auth	sufficient     pam_ssh_agent_auth.so file=/etc/security/authorized_keys
       /etc/sudoers:
	    Defaults	env_keep += "SSH_AUTH_SOCK"

       This configuration would permit anyone who has an SSH_AUTH_SOCK that manages the private key matching a public key in
       /etc/security/authorized_keys to execute sudo without having to enter a password. Note that the ssh-agent listening to SSH_AUTH_SOCK can
       either be local, or forwarded.

       Unlike NOPASSWD, this still requires an authentication, it's just that the authentication is provided by ssh-agent, and not password entry.

ARGUMENTS

       file=<path to authorized_keys>
	   Specify the path to the authorized_keys file(s) you would like to use for authentication. Subject to tilde and % EXPANSIONS (below)

       allow_user_owned_authorized_keys_file
	   A flag which enables authorized_keys files to be owned by the invoking user, instead of root. This flag is enabled automatically
	   whenever the expansions %h or ~ are used.

       debug
	   A flag which enables verbose logging

       sudo_service_name=<service name you compiled sudo to use>
	   (when compiled with --enable-sudo-hack)

	   Specify the service name to use to identify the service "sudo". When the PAM_SERVICE identifier matches this string, and if PAM_RUSER
	   is not set, pam_ssh_agent_auth will attempt to identify the calling user from the environment variable SUDO_USER.

	   This defaults to "sudo".

EXPANSIONS

       ~  -- same as in shells, a user's Home directory
	   Automatically enables allow_user_owned_authorized_keys_file if used in the context of ~/. If used as ~user/, it would expect the file
	   to be owned by 'user', unless you explicitely set allow_user_owned_authorized_keys_file

       %h -- User's Home directory
	   Automatically enables allow_user_owned_authorized_keys_file

       %H -- The short-hostname
       %u -- Username
       %f -- FQDN

EXAMPLES

       in /etc/pam.d/sudo

       "auth sufficient pam_ssh_agent_auth.so file=~/.ssh/authorized_keys"
	   The default .ssh/authorized_keys file in a user's home-directory

       "auth sufficient pam_ssh_agent_auth.so file=%h/.ssh/authorized_keys"
	   Same as above.

       "auth sufficient pam_ssh_agent_auth.so file=~fred/.ssh/authorized_keys"
	   If the home-directory of user 'fred' was /home/fred, this would expand to /home/fred/.ssh/authorized_keys.  In this case, we have not
	   specified allow_user_owned_authorized_keys_file, so this file must be owned by 'fred'.

       "auth sufficient pam_ssh_agent_auth.so file=/secure/%H/%u/authorized_keys allow_user_owned_authorized_keys_file"
	   On a host named foobar.baz.com, and a user named fred, would expand to /secure/foobar/fred/authorized_keys.	In this case, we specified
	   allow_user_owned_authorized_keys_file, so fred would be able to manage that authorized_keys file himself.

       "auth sufficient pam_ssh_agent_auth.so file=/secure/%f/%u/authorized_keys"
	   On a host named foobar.baz.com, and a user named fred, would expand to /secure/foobar.baz.com/fred/authorized_keys.	In this case, we
	   have not specified allow_user_owned_authorized_keys_file, so this file must be owned by root.
