New users to create to replicate

Dear Experts,

i would also like to know that if i have new users for sales and their names are not there in the system.

Is there any way that i could create those user names in server and then i replicate them to all the outlets????

IF possible Kindly let me know how to do it.what are the tables that i have to replicate to the outlets and can i predefine

their rights in the server???? Like once they will reach there will that be the same rights or do i have to go to stores
individually and then set their rights????

Kindly let me know!

Thanks Alot
