The core UH LDAP servers are virtually fronted with ldap.hawaii.edu and are based on the uhEduPerson schema.

Accessing LDAP
READ WELL: web apps shall not cache or log UH passwords. For security purposes special DNs will be disabled if necessary.
| LDAP Environments | host | port | comments |
|---|---|---|---|
 LDAP, Production | ldap.hawaii.edu | 636 for LDAPS, 389 if using startTLS | cleartext or anonymous binds are rejected, a Special DN is required |
| LDAP, Test | ldap-test.its.hawaii.edu | 636 for LDAPS, 389 if using startTLS | cleartext or anonymous binds are rejected, a Special DN is required |
- Connecting to LDAP is referred to as binding.
- You cannot bind to LDAP anonymously, credentials are required.
- You must request a special DN in order to bind per UH Data Governance policies.
- Special DNs are only granted when CAS (the UH Web Login Service) will not suffice.
- Special DN requests are subject to E2.215 and may require a Data Governance approval.
Our UH LDAP service features three branches
By default a Special DN provides access to the "people" and "misc" branches.
- ou=people,dc=hawaii,dc=edu
- All people who have received a UH Number, meaning anyone who was, is or will shortly be a student, faculty, staff or guest at UH.
- See also UH Role Assignments and Transitions
- The UH Online Directory relies on this branch for providing contact information for people.
- ou=misc,dc=hawaii,dc=edu
- Departmental/ Group UH Usernames
- Visiting individuals who have have been granted the ability to access the Internet from our campus(es).
- ou=dept_listings,dc=hawaii,dc=edu
- Department listings, primarily used for printing or providing PDFs of the University Phone Directory.
Data Element Dictionary
Using LDAP to verify a UH username and password
- See LDAP Authentication
- If you wish to limit use of your app to certain roles and/or campuses, you should retrieve the affiliations of the person associated with the authenticated username, and allow only those matching your criteria to pass through.
CAS recommended as an alternative to LDAP
Consider CAS (the UH Login Service) as the preferred and highly recommended alternative to using LDAP for authentication where feasible. Why use CAS?
Security
- Passwords are hidden from the app; the app does not have to be responsible for handling passwords securely
- CAS supports enhanced security with multi-factor authentication (MFA) via DUO
Convenience
- No login for subsequent apps if SSO is allowed
Consistency
- One official login page for all of UH
