sidebar login plug-in

I’m using the sidebar login plugin and need some help to redirect the user after login to custom post type content that has the same name of the user.

the plug-in has this field on admin:

Login redirect: “http://… ” (Url to redirect the user to after login. Leave blank to use the current page).

it seems to work only with static urls, like:

http://127.0.0.1:8888/client/custompostype/

but not:

http://127.0.0.1:8888/client/custompostype/%username%

Is there a way to use the %username% on that field?
thanks a lot
