I'd like to see gMSAs work on SQL Server Failover Clusters

Is the situation different with the release of SQL 2014?

I have this working in a SQL 2012 Failover Cluster Instance in a test VM environment. However, when used with Availability Groups, the failover process throws two SSPI stack dumps, before failing over successfully.

Config is detailed here:

Hi Adam,

Thank you for your feedback. Windows Server 2012 Group Managed Service Account is not currently supported as SQL 2012 released earlier than Windows Server 2012. We will consider to support gMSA in future SQL Server release.

Group Managed Service Account:
Group Managed Service Accounts (gMSA’s) (Source)
In Windows Server 2008 R2, everyone was pleased Microsoft introduced Managed Service Accounts (MSAs) to solve the security issues with domain service accounts. In Windows Server 2008 R2, however, clustered and load-balanced services could not be facilitated with MSAs. Services that spanned multiple servers required MSAs for each server. For these purposes, Microsoft introduces Group Managed Service Accounts (gMSAs) in Windows Server 8.

I'm told there's a bug in SQL 2012 though, and gMSAs do not work with clusters.

Hello Adam,
Could you please explain what does "gMSA" mean?. Are you looking for "Managed Service Accounts" support ?
