Without knowing what operating system(s) those thousand machines are running and what the naming conventions on each of those thousand machines is for user's home directories, there isn't much chance that we can help you with a request like this. Knowing what shell you'll be using on the machine where you are running this script and on each of the thousand machines you'll be querying could also make a bg difference.
And, of course, this assumes that the directory named .ssh in each user's home directory is owned by that user (and not by root). One might also want to know if any user names on those thousand machines contains the string id.

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.
