In Cisco ISE, you can authenticate administrators via an external identity store such as Active Directory, LDAP, or RSA SecureID. There are two models you can use to provide authentication via an external identity store: External Authentication and Authorization: There are no credentials that are specified in the local Cisco ISE database for the administrator, and authorization is based on external identity store group membership only. This model is used for Active Directory and LDAP authentication. External Authentication and Internal Authorization: The administrator’s authentication credentials come from the external identity source, and authorization and administrator role assignment take place using the local Cisco ISE database. This model is used for RSA SecurID authentication. This method requires you to configure the same username in both the external identity store and the local Cisco ISE database.
