My SQL Server and SQL Agent service run as a GMSA. I have a Windows File share where the GMSA has explicitly defined Full Control (not via nested group).
When attempting to run a SQL backup, an error of "access is denied" is returned.
I have also taken the UNC share permissions out of the equation by attempting to backup directly to the shared folder (\server\d$\shares\test). Same error.
Just as a test, I also tried giving the SQL server computer account Full Control permisison to that file share, but no luck.
I've read mixed things about getting this to work but am wondering if anyone here has any feedback to get this up and running?
