Use vCloud Director LDAP authentication with Veeam self-service portal

I got this request from a colleague, who was helping out a service provider with this scenario: vCloud Director is using an external LDAP service, coming from a local Microsoft Active Directory, to authenticate all vCD users. Is Veeam vCloud Director Self-Service portal able to use this authentication and allow those users to use the portal? Let’s find out (hint: yes it works!).
