Opens a shell as a different user without needing to authenticate as that user.
This is similar to the behavior of
su but it allows to execute privileged
and/or commands as any other user without needing their password.
It doesn't use PAM, instead relies on shadow files and the passwd database
to check if the given password is correct. Support for different methods of
authentication is planned.
To install use
make install and to uninstall use
make uninstall, all
other documentation is provided as man pages,
man us will give general
information about the utility and how to use it and
man us.conf contains
info about the config file format.
All platforms that store the encrypted password in
/etc/passwd should be
supported, which to this day are none. Linux is supported through
and OpenBSD through its API. Support for more systems is planned.
This program is libc-agnostic as (apart from authentication) it is POSIX
