Fixed: The given key was not present in the dictionary error in Register Managed Account in SharePoint 2013

Hi,

While trying to register a new managed account in SharePoint 2013 through Central Administration we were getting the below error.

To resolve this issue, we need to open the Active Directory Users and Computers console and select the account, right click Properties, select Authenticated Users in Security tab and
give Allow Permissions for Read Account Restrictions.

Hope it helps.
