In Part 1 of this series I explained installing and configuring Office Web Apps, in this post I am going to go
through configuring SharePoint 2013 to use my nice new shiny Office Web Apps server and the implications for licensing when it comes to editing using Office Web Apps.
Claims Based Authentication
For SharePoint 2013 to access Office Web Apps the web application must use claims based authentication. If your web application uses classic mode authentication then you will need to run a PowerShell script to convert it to claims based authentication
Convert-SPWebApplication -Identity "http://yourwebapplication:port" -To Claims –RetainPermissions
Licensing
To enable your users to edit documents using Office Web Apps you need to assign them licenses to edit.
To do this you will need to run a series of PowerShell commands
Get-SPUserLicense
$x = New-SPUserLicenseMapping -SecurityGroup <ADsecuritygroup> –License OfficeWebAppsEdit
$x | Add-SPUserLicenseMapping
Enable-SPUserLicensing
$x is a variable that holds the mapping object to input at the Add command
<ADsecuritygroup> is the AD group you want to assign the license to
Bind Office Web Apps
Once the above two items are in place you need to bind SharePoint 2013 to your Office Web Apps server, again to do this run the following PowerShell command
New-SPWOPIBinding -ServerName <WebAppServerName>
This will by default use HTTPS so make sure you use the FQDN of the Office Web Apps server
Verify It Works
The simplest way to ensure t works is to navigate to your SharePoint 2013 farm and open a Office document, if its all worked then it will open up in the corresponding Web App
If you have only assigned the editing license to certain AD groups then you will be able to see the difference in the ribbon. The 2 screenshots show one with the edit license and one without
