Create a sharepoint (document) library

Creating a sharepoint library (works in both sharepoint foundation and sharepoint server) with powershell is a nice way to ensure all libraries within sharepoint are configured the same way.

What we’ll be doing here, is creating a library, disable anonymous access on it and only allow certain user groups to have access rights to this library. We will create a document library, with 2 user groups which have contribute access rights and one group which has full control access rights. We will enable the quicklaunch link for this library and enable versioning (52 versions).

First we’ll add the sharepoint powershell snap in:

Add-PsSnapin Microsoft.SharePoint.PowerShell

After this we’ll define our defaults. We’ll be adding a Help desk user group (contribute) and an administrators users group (full control) and a users group specifically created for access rights on this library (contribute). You’d need to edit this to work on your environment.

$WebUrl = ""
$HelpDeskUsers = "DOMAIN\HelpDeskUsersGroup"
$AdminsGroup = "DOMAIN\AdminsUsersGroup"
$LibraryUsers = "DOMAIN\LibraryUsersGroup"

After setting this, we’ll get the sharepoint web application:

$SpAssignment = Start-SPAssignment
$SpWeb = Get-SPWeb -Identity $WebUrl -AssignmentCollection $spAssignment

Normally I’ll have the libraryUsers group defined by the name of the library, thus in my code I’ll have a Foreach loop in case I’d like to create multiple document libraries.

In the script below I’ll be creating the sharepoint users group, set the library type to create to ‘document library’, remove the inheritance for the library, enable quick launch, enable versioning and remove anonymous access (as I have a publically available sharepoint, but its document libraries I don’t want to be available anonymous). Then I’ll add the user groups to their specific role definition (full control / contribute), I also set the description for the library. After that I’ll close the sharepoint connection and all is done. Here is the rest of the code:

#Create a list of users groups (needed for access rights to the library)
$AllUsers = $LibraryUsers,$HelpDeskUsers,$AdminsGroup # Contribute, Contribute, Full Control
#Create the sharepoint login for the library specific users group
New-SPUser -UserAlias $LibraryUsers -Web $WebUrl -DisplayName $LibraryUsers
#Set the library type to Document Library
$ListTemplate = [Microsoft.SharePoint.SPListTemplateType]::DocumentLibrary
#Add the document library to the web application
$SpWeb.Lists.Add("$Library","$Library Shared Documents",$ListTemplate)
#Get the created document library to set specific settings
$spDocumentLibrary = $spWeb.GetList("$Library")
#Remove inheritance and remove all access entries (bool copyRoleAssignments, bool clearSubscopes)
#Add the library to the quick launch (visible to peopl with access rights to the library)
$spDocumentLibrary.OnQuickLaunch = $true
#Enable versioning on the library (default setting: only keep major versions)
$spDocumentLibrary.EnableVersioning = $true
#Set a maximum of 52 versions (1 version for each weekly documentation, thus keeping 1 year of documentation and changes)
$spDocumentLibrary.MajorVersionLimit = 52
#Disable anonymous access to this library. (Can only set 1 EmptyMask, the other one with automatically be set)
$spDocumentLibrary.AnonymousPermMask = [Microsoft.Sharepoint.SPRights]::EmptyMask
#$spDocumentLibrary.AnonymousPermMask64 = [Microsoft.Sharepoint.SPBasePermissions]::EmptyMask
#Add user (group) permissions to the library
Foreach($Users in $AllUsers)
$User = Get-SPUser -Web $WebUrl | Where DisplayName -eq $Users
If($Users -eq $AdminsGroup) { $Role = $SpWeb.RoleDefinitions["Full Control"] }
Else { $Role = $SpWeb.RoleDefinitions["Contribute"] }
$Roleassignment = New-Object Microsoft.SharePoint.SPRoleAssignment($User)
#Update the library and dispose the web application psobject
$spFolder = $spDocumentLibrary.AddItem("",[Microsoft.SharePoint.SPFileSystemObjectType]::Folder,"Documentation")


The complete script can be downloaded here

In the script, there are several items which need to be changed so the script works on your environment. First you’d need to enter the location (URL) of your sharepoint environment.

$WebUrl = ""

After that, the 3 user groups need to be changes to fit your needs. The variables in which they are stored in the script are: $HelpDeskUsers, $AdminsGroup, $LibraryUsers.
