Change App Pool User

It's Me again :-)

Our story Begins when we try to Change the user that runs the application Pool in Sharepoint 2010

We are getting the following error : 

The problem is that the Admin user in sharepoint Doesn't have enough permissions in the AD (2010) to VIEW other users.


The solution is to Enhance the permissions in AD for that user so he will be able to see other users.


(This issue has nothing to do with Sharepoint 2010, it's all about AD 2010)

Open up "Active Directory Users and Computer"

·  Select "Advanced features" from the "View" menu

·  Right-click the relevant account and select "Properties"

·  Select the "Securities" Tab

·  Scroll down and select "Authenticated users" in the "Group or user names:" field

·  Allow "Read" permissions in the "Permissions for Account Operators" field just below

·  Hit Ok


And you are done :-)
