Thanks Ray. I will try this module. I have seen the download page for this module, but there is no version for OpenERP 7, or I have to try with "thunk" version?

This module IS part of 7.0. It is shipped with the software and/or available from Settings --> Modules --> Apps.

Ok Ray. I have seen this comment "For CRM, I believe the only thing that is available on the portal is a lead generation form", and CRM is the most important information that I want isolate for every external user, so is there another module for implement permissions and security in OpenERP 7?

Is your definition of CRM the same? To OpenERP, CRM is really just leads and opportunities - the internally managed first part of the sales funnel, not customers. What exactly do you want shared to your customers?

I agree with you on the definicición of CRM, but the problem is that my client it would be like every member of the sales team had its own private CRM, but all information is available to managers, who could see everything.

Maybe portal module is not your solution.You can use the groups and rules for this porpuse. See on user configuration, Sales User: Own Leads Only

Now that I understand your question better, I think you want to look (at least) at Sales Teams.

Hi Juanjo, I need isolate all information in CRM, not only leads, but I will try this. Thanks!

Hi Ray, I didnt know about Sales Teams, I will try too this option. Multi-Company configuration can be another option, but Im not sure about this, still Im looking for a solution.

Well, after try many ways, I have see an option called "Technical options" in Access Righs for every user. If you check this option, you can get much more control and you can use many options was hidden. One of this is you can create groups, in fact, default Access Rights are the default groups en OpenERP, but you can create others, and apply rules and more control access.
