If they have /bin/false as a shell and a disabled account, then yes it=20
does :

                                                                         =
                                                   =20
uid=3D101(dhcp) gid=3D101(dhcp) groups=3D101(dhcp)

(BTW this is running as myself and not as root, which is the whole point=20
of using sudo - if you run as root, you don't really need it ...) The=20
line you will need in /etc/sudoers is something like

offlineimap localhost=3D(ALL) NOPPASSWD: /usr/bin/offlineimap

(meaning 'the user offlineimap, when connected on localhost, can,=20
without having to give her password, run the command=20
/usr/bin/offlineimap as any user'). Check the manpage though !
