Sharepoint custom permission levels

The decision to customize permission levels is less straightforward than the decision to customize SharePoint groups. If you customize the permissions assigned to a particular permission level, you must keep track of that change, verify that it works for all groups and sites affected by that change, and ensure that the change does not negatively affect your security or your server capacity or performance.

Note

You should not customize the default permission levels if your organization has security or other concerns about a particular permission and wants to make that permission unavailable for all users assigned to the permission level or levels that include that permission. In this case, you should turn off this permission for all Web applications in your server farm, rather than change all of the permission levels. To manage permissions for a Web application, in Central Administration, on the Application Management page, in the Application Security section, click User permissions for Web application.

If you need to make several changes to a particular permission level, it is better to create a custom permission level that includes all of the permissions you need.

You might want to create additional permission levels if any of the following applies:

1.       You want to exclude several permissions from a particular permission level.

2.      You want to define a unique set of permissions for a new permission level.

To create a permission level, you can copy an existing permission level and then make changes, or you can create a permission level and then select the permissions that you want to include.

Customize an existing permission level

If the custom permission level that you want is nearly identical to an existing default permission level and you don't need to use the default permission level, you can customize the default permission level to include or exclude permissions that you do or do not need.

1. On the Site Settings page, under Users and Permissions, click Advanced permissions.

2. On the toolbar, click Settings, and then click Permission Levels.

3. In the list of permission levels, click the name of the permission level you want to customize.

4. On the Add a Permission Level page, in the Name box, type a name for the new permission level.

5. Click Submit.

Copy an existing permission level

If the custom permission level that you want is similar to an existing default permission level, and you need to use both the default permission level and your custom permission level, you can copy the default permission level, and then modify the copy and save it as a new permission level.

1. On the Site Settings page, under Users and Permissions, click Advanced permissions.

2. On the toolbar, click Settings, and then click Permission Levels.

3. In the list of permission levels, click the name of the permission level you want to copy.

4. At the bottom of the page, click Copy Permission Level.

5. On the Copy Permission Level page, in the Name box, type a name for the new permission level.

6. In the Description box, type a description for the new permission level.

7. In the list of permissions, select or clear the check boxes to add permissions to or remove permissions from the permission level.

8. Click Create.

Create a permission level

If there is no permission level similar to the one you need, you can create one and include just the permissions that you need.

1. On the Site Settings page, under Users and Permissions, click Advanced permissions.

2. On the toolbar, click Settings, and then click Permission Levels.

3. On the toolbar, click Add a Permission Level.

4. On the Add a Permission Level page, in the Name box, type a name for the new permission level.

5. In the Description box, type a description for the new permission level.

6. In the list of permissions, select the check boxes to add permissions to the permission level.

7. Click Create.
