it's not a matter of users but concurrent batches... a study by Microsoft
indicates a magic number of 25, but it really depends on the application
type/design, database type/design...
of course bad ADO serverside cursors design will be worse then excellent
clientside disconnected design code...
but actually there's no limit, just the buuilt-in Workloads Gevernor that
kicks in when more then 8 concurrent batches are in progress... you can have
a look at

fro further info about that governor...

actually not... you have to test saving and trap the relative exception...

I think you've better drop your user tables and rely on the standard SQL
Server users and roles...you are duplicating all and incurring in troubles..
