com.adobe.granite.security.user.UserProperties Java Class: what's the difference between authorizableId vs principalName?

[jayv25585659]

I created a new user (ID=a0001) in my local AEM and both functions give me the same value (which is a0001).

The Adobe reference document is not very clear on the distinction. Thanks

EDIT: I had a look in CRX/DE for the properties of a0002 user and rep:principleName and rep:authorizableId has the same value.

String principalName = userProperties.getPrincipalName();
String authorizableID = userProperties.getAuthorizableID();
