Sudo to delegate permission from non-root user to another non-root user
I've been through many threads before i decide to create a separate thread.
I can't really find the solution to my (simple) problem.
Here's what I'm trying to achieve:
As "canar" user I want to run a command, let's say "/opt/ocaml/bin/ocaml" as "duck" user.
The only to achieve this is to give "canar" user root permission in sudoers, see below:
Host_Alias LAB = linuxbox
User_Alias LABTRUSTED = canar
Cmnd_Alias LABADMIN = /bin/bash, /bin/su, /bin
LABTRUSTED LAB=(ALL) NOPASSWD: LABADMIN
And run any command:
canar@linuxbox$ sudo -i -u duck 'id'
But basically, this is a huge security hole since canar can run whatever he wants as anyone (including root)
I want to restrict canar user to be able to login as duck user (or as anyone from a given group) without providing root access
Edit: want to restrict canar user to be able to run an identified command as duck user (or as anyone from a given group) without providing root access
Any help would be welcome!

pdebuild-user-mode-linux
pdebuild-user-mode-linux(1) pbuilder pdebuild-user-mode-linux(1)
NAME
pdebuild-user-mode-linux - pbuilder-user-mode-linux way of doing debuild
SYNOPSIS
pdebuild-user-mode-linux [pdebuild-user-mode-linux options] -- [pbuilder-user-mode-linux options]
DESCRIPTION
A convenience program for pbuilder-user-mode-linux which invokes pbuilder after obtaining appropriate root privilege in a Debian source
directory. One must be inside the source tree containing the debian directory, in order to make it work.
PDEBUILD OPTIONS
--buildsourceroot [fakeroot]
The command used to gain root privilege for invoking dpkg-buildpackage
--auto-debsign
Invoke debsign at the end of pdebuild process.
--debsign-k [key-id]
Pass -k option to debsign to specify which keyid to sign.
--buildresult [Directory for build results]
The place which build result is stored.
--configfile [Extra config file to use]
The configuration file is used, but not passed on to pbuilder-user-mode-linux.
--debbuildopts [options to pass to dpkg-buildpackage]
The space-delimited list of options are passed to dpkg-buildpackage. This option appends to pbuilder option --debbuildopts and may
also be used to reset the list of options by passing the empty string.
--use-pdebuild-internal
Uses a different implementation of pdebuild, which calls clean and build inside the chroot, using bind-mounts.
pdebuild-internal tries to run debian/rules clean inside the chroot. To achieve the goal, the working directory is passed on inside
the chroot, in the form of bind-mounting and debuild is run.
This option will not protect the working directory and its parent directories from the build scripts.
-- [pbuilder options]
After the -- symbol, an arbitrary number of pbuilder options can be specified. See pbuilder-user-mode-linux.1 for full list of
options.
There is an exception that --buildresult needs to be specified as pdebuild option before the -- to be effective.
FILES
/etc/pbuilderrc
The configuration file for pbuilder-user-mode-linux, used in pdebuild-user-mode-linux.
/usr/share/pbuilder/pbuilderrc
The default configuration file for pbuilder-user-mode-linux, used in pdebuild-user-mode-linux.
