You can configure IBM® QRadar® to use supported Lightweight Directory Access Protocol (LDAP) providers for user authentication and authorization.
QRadar reads the user and role information from the LDAP server, based on the authorization criteria that you defined.
In geographically dispersed environments, performance can be negatively impacted if the LDAP server and the QRadar Console are not geographically close to each other. For example, user attributes can take a long time to populate if the QRadar Console is in North America and the LDAP server is in Europe.
You can use the LDAP authentication with an Active Directory server.
