I have several domainnames registered and i have created several protals in one DNN install.

when i create a new website for a customer i create it with a name "admin" and a assigned password. that is the password i use to control my environment (i could use host, but i do not. in every portal i create i create an account with firstname+lastname = sitename for recognition, and a login "admin" and a password. in the early versions this sometimes created problems with "this account already exist." But now... i have a new problem.
every website created with this method has in the asp_net_users a new account ID with the name admin but the users table in dnn has only 1 admin name in it. and it carries the last name of the last added website admin.

it is not a problem to logon, but if i check the site settings / advanced settings / other settings i see the wrong account. to fix it for the current website i have to enter the user information page by clicking upper right on the name of the admin and click update. (after editting a record)

if i go back after the update i see the correct name. (in the userstable the name is updated. but it should be another user) When i try to see what happens i only see that the accounts all have the same id in the different portals (userid=2 = admin)

so i want to fix this, how do i do that?
