To modify attributes of Inactive user using Workflow

Hi Guys,

I am trying to modify the attributes of Inactive users who are in inactive container through a workflow.
But when i am submitting the workflow i am getting an error saying " User not authorized for action on this entity" and i am not able to submit the workflow.
Is this because of any permission issues on modifying inactive users. Or is this due to the permission issues on Inactive container.
Can anybody help me in this issue?




Thanks
