   https://HOST/SAAS/t/TENANT/auth/oauthtoken?grant_type=password

3. Use this body format with POST request:
   
   username=<USERNAME<EM>>&password=<PASSWORD>&client_id=<CLIENT_ID>&domain=<USER_DOMAIN>
   
   Note:
   • Replace the <HOST>, <TENANT>, <USERNAME> and <PASSWORD> with the respective values.
   • <USERNAME> must be entered the same way it is entered on the login page.
   • The <DOMAIN> is the fully qualified name of the domain of the user. It can be find by navigating through vRA UI Administration > Users & Groups > Directory Users and Groups.
   • The <CLIENT_ID> can be found in /etc/vcac/solution-users.properties. For this request to work you will need the cafe_cli client. Following script should print it in the console:
     
     (grep -i cafe_cli= /etc/vcac/solution-users.properties | sed -e 's/cafe_cli=//')
