- Logon Id (usually something like uid, sAMAccountName, or mail)
- Email address
- Password
- Display Name (usually either cn or displayName)
- Unique Identifier (these can be changed as per this page):
- MS Active Directory: objectGUID
- Domino: dominoUNID
- Novell eDirectory: guid
- Tivoli Directory Server: ibm-entryUUID
- Sun Directory: nsuniqueid
Note: These are the minimum attributes that you need in order to successfully login. Extra information such as managerId, secretaryId, departmentId, orgId, etc would need to be loaded into Profiles, but it doesn't have to come from an LDAP. Hopefully that makes sense.
