Is there a way to get my Database to only open for users of the
workgroup I created. I created a database and a workgroup, but some
people are able to log in as an Admin without even joining the group.
Then you missed a step in setting up security. When done properly it behaves
just like you are requesting it to.
When they open the file using a workgroup that does not ask them for a user name
and password then they must be creating a session as the user "Admin" who is a
member of the group "Users". Neither of those entities should have permissions
to open your file. The fact that they get in means that those entities DO have
permissions that you should have removed.
Also make sure that "Admin" is not still the owner of the database. Owners have
rights above and beyond the permission settings you give to them.
