name: LDAP
full_form: Lightweight Directory Access Protocol
context: Only in those cases having inter-operator operations, the protocols are an issue. These include FTP, HTTP and LDAP for repository access, OCSP [2] for certificate status checking and CMP [4,5] or CMC [6] for certificate life cycle management. End entities (EEs) need to be able to fetch CRLs in order to check the certificate status from a PKI repository. Also, in the case of multi-level CA hierarchies and cross-certification, EEs might need to fetch the certificates between the other party and the trusted CA in the certificate path (the EE certificate itself should be sent in the IKE payload). Both LDAP (Light-weight Directory Access Protocol) and HTTP should be supported for fetching CRLs from a repository. HTTP is very widely used, easy to implement and often used to fetch CRLs. However, LDAP is more suitable for fetching other objects as CRLs. CRL distribution point in the EE certificate or sub-CA certificate should point to the CRL issued by the CA. LDAP should be the supported
description: LDAP (Lightweight Directory Access Protocol) is a protocol used for accessing and managing directory information services over an IP network. In the context of 3GPP TS 33.810, it is mentioned as one of the protocols supported for fetching Certificate Revocation Lists (CRLs) from a repository.
explanation: The text explicitly states that LDAP is a protocol used for accessing and managing directory information, aligning with its definition as a set of rules governing data transmission in telecommunications.
