sn

Definition

The surname is one of the standard LDAP attributes defined in RFC 2256 http://www.faqs.org/rfcs/rfc2256.html that UCLA Enterprisee Directory adpots. According to RFC 2256, sn, also known as X.500 surname, "contains the family name of a person." In the context of UCLA ED, this is the last name of the person represented by the identity entry in the UCLA Enterprise Directory.

Data Flow

The Enterprise Directory retrieves LAST_NAME_PERSON from the UID system via the Campus Data Warehouse (CDW) in real-time manner. For each person, the UID system contains names recorded at 4 different university systems. They are Student Record System (SRS), Student Information System (SIS), Payroll Personnel System (PPS), and University Extension System (UNEX). Names from these systems are flagged in APP_ID field accordingly as SR0, SI0, PP0, and UNX. The Enterprise Directory select the name to populate cn base on the following logic:

  • a. If a person currently has student affiliation (flagged as "SRSAffiliated" in uclaPersonDirectoryListAffiliation), select the name in the order below no matter what other affiliation this person has:
    • 1. SR0 name
    • 2. SI0 name
    • 3. PP0 name
    • 4. UNX name
  • b. Else, if a person currently has employee affiliation (flagged as "PPSAffiliated" in uclaPersonDirectoryListAffiliation), select the name in the order below:
    • 1. PP0 name
    • 2. SR0 name
    • 3. SI0 name
    • 4. UNX name
  • c. Else, meaning a person does not have either student of employee affiliation, go with the same order of step a.
  • Note: If the name selected is found with APP_USAGE_STATUS <> 'A', an error message will be logged but the name still goes in ED.
