SharePoint '10 Unique permissions trickling up to parent permissions

Posted on 2011-05-10

In SharePoint 2010, if I go into a list and then edit its permission, I tell it to stop inheritance, and then let's say I grant/add x amount of people in there with any specific permissions. Good so far.
Well if I go into another list, edit its permissions, it says it's inheriting from main site permissios, only I see the individual people there I added as unique permissions from the OTHER list.

What would make my unique permission settings to a particular list be applied to the parent SharePoint website?
Shouldn't it be separated/isolated permissions and not affect the entire site's?

What's interesting is that it just shows their names in there as limited, it doesn't keep their contribution or approval permissions with their name when it's magically added to the parent site permissions.  

If I go into inherited permissions and remove the user's, those users then disappear from the other Lists' unique granted permissions.

So what's making unique list permissions trickle up to the inherited's settings' permissions?

Edit: The users I add in any list will show in all other lists with Limited Access .
Is this just by design?

    With unique permissions, users will get added to levels above as "limited access".  This is by design.

    Ah ok, thanks. Just didn't seem right to me being new to SharePoint.

    So is the only way to add specific contributors to lists or pages to grant their user names, or is it better to create a group (even if it's 2 people in the group) and just give that specific group Contributor access to the appropriate resources?

    Just depends on your governance.  There is not "best practice"....just depends on the situation.  Honestly I try not to break inheratance lists.
