Error on CRM Integration

Hi all,

After integrating CRM with microsoft dynamics NAV 2016, in the test connection stage showing error message as below

Microsoft Dynamics NAV

The connection test was successful. The settings are valid.

However, because the Dynamics NAV Users Must Map to Dynamics CRM Users field is set, Dynamics CRM integration is not enabled for OSIUS\AKOLAPPAN.


I have tried a lot by surfing in web. No solutions found. if anyone replied it would be very appreciable.
