Msaccess User, Groups and Ribbon

I have a Database in MSAccess.
I’d like to build a vba class that depending on the user group from the domain Windows Server 2003 load the suitable Ribbon.
For example, for those who are in the domain group ‘Administrators’, I’d like to open one menu and for ‘Workers’

Is it that possible? Anyone could give some piece of code?

Thanks in advance
