QNAP and Synology both have models that have an LDAP Server -- those are the keywords you need to find.

If you use Google Apps for Business, with your own domain, you can have Single SignOn (SSO) very easily with Synology. It's possible with QNAP, but is directly accessible in Synology.

Many NAS's have an LDAP Server directly available. The key is to make sure the model you pick has the LDAP Server.

>>If you're contemplating linking more than 4 or 5 computers together I strongly recommend setting up a Windows domain. This requires an actual Windows server computer to act as an Active Directory/Domain Controller (DC). These days there are some file-sharing Network Attached Storage (NAS) devices which can act as Windows DCs despite not running Windows; they can be a lower-cost alternative to a true Windows server.

>Re NAS boxes running as a DC - do you remember which one(s)? I have one smaller customer who I would like to be on some sort of DC but they do not want to jump to having (or more accurately "paying for") a new server. They choke on the $1000 or so for a Win server license. And these NAS boxes, what are they actually running for the DC - I take it not a Windows domain but some other OS?
