Setting up AD Group permissions

Hi All,

We have an AD group for our Data Center that we want to give permissions to in Orion.  I've gone in to 'Manage Accounts' and chose to create a new 'Windows Group Account'.  I was able to search AD and choose the group that I want to give access to but none of the members of the group can login.  They keep getting an error "Login Failure.  username and/or password incorrect".  This is happening for all members of the AD group.  Am I missing something?

Versions:

Orion Platform = 2014.1.0

SAM = 6.1.0

Thanks for any answers or suggestions

Greg
