This page provides a description and examples of the key attributes that are needed to support and enforce appropriate access to CCC-wide services and cloud services. These are the attributes which need to be supported by college/district Identity Providers, and released to various services inlcuidng the CCC IdP Proxy.

The eduPerson schema ( http://software.internet2.edu/eduperson/internet2-mace-dir-eduperson-201602.html ) has a more detailed description of many of these attributes and their intended meaning and purpose.

Using Your College Identity to Access CCC-wide and Cloud Services – the Importance of eduPersonPrincipalName

When your users login to services at your college/within your district, they enter a Username and a password. Most commonly that Username is matched against the sAMAccountName or the uid attribute for the user in your Active Directory or other LDAP directory. Sometimes, particularly for students, you might actually have the student enter some other student identifier as their Username. Generally, most colleges don't require their users to add a '@college.edu' type suffix when they enter their Username. 

However, for CCC-wide and Cloud Services, which can provide services to many different institutions, having a user identifier that is "globally unique" is very advantageous. And such an identifier has been defined, an identifier called eduPersonPrincipalName, or EPPN for short. It was defined first as part of the eduPerson schema, linked to above. EPPN has the syntax of an email address, and might even "work" as an email address, but its purpose is to be a  globally unique federated identifier, rather than an email address. It is generally the most important attribute to be shared with federated services.

The standard practice in the Higher Education community is that EPPN is constructed by taking some local campus identifier (often SAMAccountName or uid, but sometimes some other local identifier like an employee or student id number), and adding to it a suffix of the form:  @college.edu.  So the EPPN for Jane Smith, who has a sAMAccountName of jsmith, at Best Community College that has a campus domain of bestcc.edu, will typically be jsmith@bestcc.edu. But depending on how the college manages the sAMAccountName attribute for its users, if Jane Smith has a student id of 12345678, the college might choose to make her EPPN be 12345678@bestcc.edu instead.

Here are the important considerations to keep in mind in considering what your college/district should use as the EPPN for each of their users:

eduPersonPrincipalName (EPPN)


urn:oid:1.3.6.1.4.1.5923.1.1.1.6

The primary federated identifier of a given user from a college/district IdP.

jsmith@college.edu

12345678@college.edu

Important things to keep in mind when choosing the identifier to be used to the "left of the @" for EPPN:

  • is unique within your user base
  • is never re-assigned to another person
  • is persistent, and never (or rarely) changes

EPPN has the syntax of an email address, and might even "work" as an email address, but it should be considered a "globally unique federated identifier" rather than an email address. It is generally the most important attribute to be shared with federated services. Note that the value of EPPN does not have to match what the user fills in as their username when they login, and the user does not need to know what their EPPN is, as it is shared between the IdP and the service.

EPPN is most often not an actual attribute in your directory, it is "constructed" by the IdP. Everyone from your institution should have the same "suffix" (the value to the right of the @), and that should always be the primary DNS domain of the campus. (I.e. college.edu). If the sAMAccountName has the right properties to satisfy the needed identifier, than a very typical EPPN would be "sAMAccountName@college.edu". But the identifier to the LEFT of the @ does not have to be the sAMAccountName, nor the username the user logs in with, it can be any identifier that makes the most sense for your campus, any identifier that satisfies the properties listed to the left here. And the identifier you choose to use to the "left of the @" can even be different for staff versus students.

eduPersonAffiliation

 

urn:oid:1.3.6.1.4.1.5923.1.1.1.1

Role within the institution
  • staff
  • student
  • member
  • employee
  • faculty
  • affiliate

All of the roles a given person has within the college, but only the values defined in the eduPerson schema are allowed for this attribute, you can't make up "new values" for it. The affiliate value identifies a person that has applied to one or more colleges but is not a student yet.

This is the only attribute listed here that is intended to have multiple values. All the rest are expected to have a single value.

eduPersonPrimaryAffiliation

 

urn:oid:1.3.6.1.4.1.5923.1.1.1.5

Primary role at the institution
  • staff
  • student
  • faculty

Must be one of the values specified in eduPersonAffilliation. If the eduPersonAffiliation attribute has many values, the primary affiliation should reflect the role to be associated with services that differentiate based on this value (such as the CCC Portal).

For example, if the user is both a staff member and a student, and the primary affiliation is staff, the portal experience will be geared towards a staff member.

uid

urn:oid:0.9.2342.19200300.100.1.1

UsernamejsmithThis is usually the value that the user fills in as their username when they login. If you are using AD, the usual attribute you want to use to populate uid is the sAMAccountName attribute.

The CCCID The CCCID is a critical attribute for students. If not specified, but required for a portal or service action, the CCCID will be looked up via the EPPN. If no match is found, the action cannot be performed until the user creates a CCCID via the OpenCCC portlet.

 

Optional Attributes

These are optional attributes that can be sent by the college. One example use is that these can be used to pre-populate values when the user is required to create a central CCCID account.
