Share Permissions

I ran into a question about allowing a user to create a share and the answ I choose was give them full control permissions over the drive to allow them to create shares off of it . But needless to say I was wrong the full control share permission allows you to read change.
In the explination it said that only Power User and Admins have the create a share permission. My question is what permission do you need to share a file or folder in a domain. Cause I know any one with ownership can share any thing in a workgroup. But I was kinda wondering that other user should be able to share besides the PwrUsr and Admin in a domain.
