Change "exo" default portal

[skabeat@xxxxxxx]

Hi,

I'm trying to find a way to change the default portal.

If I start the exo ecm wrinting down http://localhost:8080/ecm/ it will bring 
me
to
http://localhost:8080/ecm/faces/public/exo.

If I'm logged in with any user and I log out, it will be the same : I'm 
directed
to http://localhost:8080/ecm/faces/public/exo.

How can I do to modify this behavior, and to get a diferent default portal 
user
that is not "exo"?

Thanks for your help!
