Windows Server 2012 includes new functionality, called Group Managed Service Accounts (gMSA), which provides a useable solution for password management for service accounts. Specifically:
- A single gMSA can be used on multiple hosts.
- A gMSA can be used for scheduled tasks.
- A gMSA can be used for IIS Application Pools, SQL 2012 and potentially other applications.
More information on gMSAs can be found here.
