howto delete blackout from other users in GRID.

Good morning,

with emcli you can delete a blackout as follows :

./emcli delete_blackout -name="TESTBLACKOUT"

But even when i login as sysman from this commandline I cannot delete a blackout created by an other administrator.

I can however delete blackouts blackouts from other owners with the EM console.

is there a workaround for this problem ?
