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.

Hello, Can you config sudo to use the passphrase in the user ssh-key instead of the one in the passwd? Some users do not have local passwords on the system and instead of adding the NOPASSWD in sudoers I would like the solution I asked about above. Thx Jocke (3 Replies)

newgrp

NEWGRP(1)							   User Commands							 NEWGRP(1)

NAME

       newgrp - log in to a new group

SYNOPSIS

       newgrp [-] [group]

DESCRIPTION

       The newgrp command is used to change the current group ID during a login session. If the optional - flag is given, the user's environment
       will be reinitialized as though the user had logged in, otherwise the current environment, including current working directory, remains
       unchanged.

       newgrp changes the current real group ID to the named group, or to the default group listed in /etc/passwd if no group name is given.
       newgrp also tries to add the group to the user groupset. If not root, the user will be prompted for a password if she does not have a
       password (in /etc/shadow if this user has an entry in the shadowed password file, or in /etc/passwd otherwise) and the group does, or if
       the user is not listed as a member and the group has a password. The user will be denied access if the group password is empty and the user
       is not listed as a member.

       If there is an entry for this group in /etc/gshadow, then the list of members and the password of this group will be taken from this file,
       otherwise, the entry in /etc/group is considered.

CONFIGURATION

       The following configuration variables in /etc/login.defs change the behavior of this tool:

       SYSLOG_SG_ENAB (boolean)
	   Enable "syslog" logging of sg activity.

FILES

       /etc/passwd

       /etc/gshadow
	   Secure group account information.
