Additional Functionality in SharePoint 2010
Managing users and groups from the graphical user interface has become a lot easier in SharePoint 2010, and with the use of the Office Ribbon, it has become much more user-friendlier As we mentioned in 1, the Check Permissions feature makes it possible to check which permissions a specific user has on the site, including the permissions obtained through membership in Active Directory groups that are added to the site When creating new sites from the user interface, you can specify if the site should inherit permissions from the parent or if it should have unique permissions If you select unique permissions, you will be presented with a page where you create or select three existing user groups that will be used for hosting viewers, members, and owners of the site, as shown in Figure 19-1 These are known as associated groups

Even though the Viewers, Members, and Owners groups have a default permission level assigned, you can change the permissions, as shown in Figure 19-2 For example, you might choose to prevent contributors from modifying the site using SharePoint Designer or other remote interfaces Through the graphical user interface, you can easily remove users from SharePoint groups For example, when a user has left the company, you can delete the user s

profile from the User Profile Service application, as shown in Figure 19-3 This will remove the My Site for the specific user Then when you click the user s name somewhere within SharePoint, you will get to the current site s local user information page instead of the user s My Site From here, users with sufficient permissions have the option to remove the user from the site collection, and that user will then be deleted from all SharePoint groups within the site collection NOTE Users are never completely removed from SharePoint This is to avoid having content items with unknown authors

Summary
In this chapter, we looked how to use Windows PowerShell to manage SharePoint users and groups by creating several reusable scripts We used the Add and Delete methods of the SPGroupCollection class to create and delete groups When modifying groups, we first retrieved the group using the SiteGroups property of the SPWeb class We also demonstrated how to work with users using the Get-SPUser, New-SPUser, Set-SPUser, and Remove-SPUser cmdlets
Working with Content Databases
PowerShell for Microsoft SharePoint 2010 Administrators
s the use of SharePoint increases within the organization, it is very common to see the amount of content stored in SharePoint grow dramatically This makes it necessary to increase the number of content databases to maintain good performance Having a large number of content databases is not a problem in itself, since SharePoint 2010 supports hundreds of content databases per Web application The issue is that it s important to maintain a good naming standard for all those databases Unfortunately, it is very often the case that there is no naming standard applied at all, causing difficulties in distinguishing which content databases are used by which Web application This makes troubleshooting more difficult, not to mention the frustration it causes the SQL Server team In our first scenario in this chapter, we will address the database-naming problem by creating a Windows PowerShell script that first detaches all content databases from a Web application, renames them on SQL Server using a defined naming standard, and then reattaches the content databases to the Web application This will create consistent database names on SQL Server and remove database names containing GUIDs and similar elements By default, any binary large object (BLOB) in SharePoint 2010, such as the contents of a document in a document library, is stored inside a content database, in a column of type IMAGE As usage increases, the total amount of BLOB data can easily outgrow the structured data stored in your content databases, thus making database operations less efficient To address this, SharePoint 2010 offers the ability to use Remote BLOB Storage (RBS) providers, allowing you to configure your Microsoft SQL Server 2008 to store the BLOB data outside the database using more cost-efficient storage solutions In our second scenario, we will look at how to configure SharePoint 2010 and Microsoft SQL Server 2008 to use the RBS FILESTREAM provider included in the Microsoft SQL Server 2008 R2 Feature Pack
