Is there any practices or SID classes for user identity information, like ActiveDirectory domain login or Facebook ID? I couldn't find any info in SID or Open API documents regarding usernames. In Party Management API REST specification Individual entity has "externalReference" array with IDs, but I'm not sure if it's a good idea:
"externalReference": [ { "href": "http://facebook.com/17263635", "type": "FacebookID" }, { "href": "http://google.com/17263635", "type": "GoogleID" } ]
