why do some customers show up in User directory

[Kees Bloemendaal]

I want Customers to my Service Desk to be Customers, not Users in my organisation. Some of them do show up as User in my Organisation. It seems like I have to Suspend Access to them in de People directory to get them removed as a user. But that also removes them as a customer...

It's a shame that there's no answer to this, as this is the situation I'm facing.

I think I might have figured out what's going on for us:
We have a portal with a login page for Customers, but this page also functions as a sign-up page. If I go to the Customers section and add a new Customer they stay as a Customer, but if someone signs up themself in the portal they become a User (who is also Customer).

The only workaround I've been able to come up with is to have a shouty message on the login page telling people not to signup if they don't have a login.
