SharePoint 2013 - I'm planning to use 'unattended service account' method of Secure Store Service - for Excel, Performance Point and Visio services. I'm about to create Active directory accounts for them.
Question: Do we need separate Active directory accounts for each service DomainName\ExcelUnattendedAccount DomainName\PPSUnattendedAccount DomainName\VisioUnattendedAccount
Can I have just one Active Directory account DomainName\SharePointUnattendedAccount ?
Are there any drawbacks having a single account? Any best practice around this? For all the three services the data sources are going to be the same.
