Some times in sharepoint 2010 we need to have to view/delete the users from site collection, moreover in sp2010 we don’t have any link as “All People” as it is present in MOSS2007. So it is a tedious process to view/delete the users from site collection.
For this purpose what we can do in sp2010 is:
Go to Site Actions –> Site Permissions.
Click on any of the groups and you will see the url of your page containing the string
What you need to do is just replace the “_layouts/people.aspx?MembershipGroupId=8” to
“_layouts/people.aspx?MembershipGroupId=0” and omit the succeeding part of the url (if present) and reload the page.
You can now view all the users in that site collection and also have an option in the breadcrumb to remove the user from site collection.
