manager login behaviour

Hi,

I found something I never faced before (but as far as now, I never had to play very much with different manager role in Evo)
I have a couple of redactor user for wich I did a redactor role and all the necessary permissions.

I did ALSO for those people a WEB USER account because they could have private pages in frontend, and very logically(to me) I named those webuser with the SAME login name I used for the manager’s user.

I thought those objects where really different, so whatever they are named nobody is supposed to care.
Ok

Now when hiting the /manager and entering their login information, Modx lets then come in, BUT redirects them to the WEBUSER landing page (the one configured for each user to go when logged in in frontend.

So they have to click on the previous page in browser history o get back to the manager. Quit annoying

Did I missed something ?

thank you
