PR4100 authentication and authorization

Hi All - I’m wondering if there is a way to connect my PR4100 to Google Directory Service without having to use an Active Directory from Microsoft - Do you know if it is possible? There is a way to use, for example, open SAML 2.0 with PR4100? Any other ideas?

The fact is: I don´t want to spent a lot of money with MS AD…

Thanks in advance.

Certain Western Digital My Cloud devices including PR4100 support only MS Active Directory service.
