Creating User Overrides for Spaces

Create a user override to grant a particular set of permissions to an individual. You might need to create an override if:

A person requires a particular set of permissions for an area, but isn't (and shouldn't be) a member of a group to which you've already assigned permissions for the area.
A person is a member of a group to which you've assigned permissions for an area, but they require a different set of permissions than they've received as a member of the group -- in other words, they're an exception to the rule. For example, you might want to separately define their permissions in order to enhance or limit their access in the area.

Use the following steps to create a user override on the permissions page you're  editing:

Under User Overrides, click Create a user override.
In the box, start typing the name of the user for whom you want to set the  override. Click the popup that displays the user's name.
Click the Set exception button to view the permissions you can set.
In the Set Exception dialog, select the access and content type permissions.
Click Save.
