All entries stored in an LDAP server have a unique DN. Another advantage of performing a search operation first and a bind operation later is that the DN received in the search result can be used as the user DN instead of forming a DN by prefixing the username (cn attribute) with the base DN.
#CISCO IOS XE AND DIAMETER AAA PASSWORD#
If a password attribute is not returned, the bind operation can be performed later. Thus, there is no need to perform an extra bind operation.
#CISCO IOS XE AND DIAMETER AAA VERIFICATION#
This is because, if a password attribute is returned as part of the search operation, the password verification can be done locally on an LDAP client. In LDAP deployments, the search operation is performed first and the bind operation later. In the absence of a root DN and password, an anonymous bind is performed. LDAP supports the following binds:Īn authenticated bind is performed when a root distinguished name (DN) and password are available. The client specifies the protocol version and the client authentication information. It is used to start a connection with the LDAP server. The bind operation is used to authenticate a user to the server. TLS support for LDAP is mentioned in RFC 2830 as an extension to the LDAP protocol. Each certificate includes the name of the authority that issued it, the name of the entity to which the certificate was issued, the entity’s public key, and time stamps that indicate the certificate’s expiration date. Certificates are issued by Certificate Authorities (CAs). It relies upon certificates, public keys, and private keys for clients to prove the identity. Transport Layer Security (TLS) is an application-level protocol that enables secure transactions of data through privacy, authentication, and data integrity. LDAP authentication is not supported for interactive (terminal) sessions. Unsolicited messages or notifications from the LDAP server are not handled. If you are using a secure Transport Layer Security (TLS) secure connection, you must configure X.509 certificates.

The AAA framework provides tools and mechanisms such as method lists, server groups, and generic attribute lists that enable an abstract and uniform interface to AAA clients irrespective of the actual protocol used for communication with the AAA server. Lightweight Directory Access Protocol (LDAP) is integrated into Cisco software as an authentication, authorization, and accounting (AAA) protocol alongside the existing AAA protocols such as RADIUS, TACACS+, Kerberos, and Diameter.
