Explanation
The third-party help desk needs to perform Tier 1 functions including password resets. Password resets require direct interaction with the enterprise directory service. LDAP (Lightweight Directory Access Protocol) is the standard protocol used to query and modify directory objects, including user accounts and credentials. The firewall change described would open the LDAP port (389) or LDAPS port (636) to allow the third-party provider to connect to the internal directory. RADIUS is used for network access authentication (VPNs, wireless) and does not support directory management operations like password resets. SAML and OpenID are federation protocols for single sign-on - they authenticate users but do not provide directory management. WAYF ('Where Are You From') is a federation discovery protocol used in academic identity federations, not applicable here.
