This forum is for the support of the CRM 4 portals only. If you have questions about the CRM 2011 versions, please use this other forum:
CRM 4 doesn't have an employee self service CAL, so if you have an employee, they require a full CAL in order to use CRM 4. The external connector is only to be used for non-employees or agents of the company.
CRM 2011 introduced the concept of an employee self-service CAL which will is roughly 10% of the cost of a full CAL. The new ESS CAL will allow for the use of the portals to manipulate the data on behalf of that employee.
That said, the distinction of an employee is important - if it is your employee, a CAL is required. If it is an employee of one of your customers, then an external connector will cover them. Your wording doesn't help me understand the relationship
between you and that 'user'. I don't know what you mean by "client/customer employee" or "client employee". You will have to determine if that user is your employee orcontractor, or if they fall under the terms allowed in the external connector.
