Hello!
I have a problem installing Sugar Portal 5.1 for SugarCRM 5.1 professional.
I follow every step of the Sugar Portal User Guide tutorial, and when I arrive at Step 3: Site Configuration. I fill the text boxes with my dates:

Site Configuration
* URL of Sugar Portal Instance: http://localhost/sugarpro/portal/
* URL of Parent SugarCRM Instance: http://localhost/sugarpro/
* SugarCRM Portal User Name: prueba
* SugarCRM Portal User Password: prueba
This is name of the user set up at the Portal User in the Parent install.
Use Defaults? : Yes

and when I press "next" button the following message appears: "There was a problem logging into the Parent SugarCRM Instance. Please double check the SugarCRM Portal User Name and Password."
The user "prueba" was created as "portal user only" and was relationated with a contact with "Portal Information" filled.
Please, could anyone give me a solution? I can't continue with the instalation due to this problem.
Thanks
