Personally Identifying Information (PII): These attributes may identify an individual and all rarely, but can, change. sn, givenName, anddisplayName are not necessarily unique to an individual and change with greater frequency.
eduPersonPrincipalName: A unique identifier for the user that is usually human-legible and is of the form userid at domain. Reassignment is permitted and reassignment practices vary substantially throughout InCommon.
mail: An email address for the user. Please don't use mail as an identity key, as it may be reassigned, frequently changed, or in a third party domain.
sn: A user's surname.
givenName: A user's first (and second, third, etc.) name.
displayName: A display name for a user.

NET+ recommends against the use of cn in favor of givenName and/or displayName because of the many and various interpretations and uses of cn.
