You are going about this all wrong. Give everyone his own account. On each system, create an admin group. Give the admin group root power via sudo by adding a line to sudoers like this:

Code:
%admin ALL=(ALL) NOPASSWD: ALL

If a user should be able to access a system at all, add his private account to that system. If he needs root access as well, add his account to the admin group. Now he can log on to the box and them use sudo to obtain root authority.

NAME
pam_timestamp - authenticate using cached successful authentication attempts SYNOPSIS
auth sufficient /lib/security/pam_timestamp.so session optional /lib/security/pam_timestamp.so DESCRIPTION
In a nutshell, pam_timestamp caches successful authentication attempts, and allows you to use a recent successful attempt as the basis for authentication. When an application opens a session using pam_timestamp, a timestamp file is created in the timestampdir directory for the user. When an application attempts to authenticate the user, a pam_timestamp will treat a sufficiently- recent timestamp file as grounds for succeeding. ARGUMENTS
debug turns on debugging via syslog(3). timestampdir=name tells pam_timestamp.so where to place and search for timestamp files. This should match the directory configured for sudo(1) in the sudoers(5) file. timestamp_timeout=number tells pam_timestamp.so how long it should treat timestamp files as valid after their last modification date. This should match the value configured for sudo(1) in the sudoers(5) file. verbose attempt to inform the user when access is granted. EXAMPLE
/etc/pam.d/some-config-tool: auth sufficient /lib/security/pam_timestamp.so verbose auth required /lib/security/pam_unix.so session required /lib/security/pam_permit.so session optional /lib/security/pam_timestamp.so CAVEATS
Users can get confused when they aren't always asked for passwords when running a given program. Some users reflexively begin typing information before noticing that it's not being asked for. SEE ALSO
