Where is polkit-auth ?

[Mathieu Malaterre <mathieu.malaterre@gmail.com>]

hi all,

  I am trying to add shutdown right to another user on my
debian/squeeze system. I thought I could just do:

polkit-auth --user user2 --grant org.freedesktop.hal.power-management.shutdown

  However polkit-auth has completely disappear since lenny, where did it go ?

Thanks
