Etude de cas 21 : Exemple d'intégration de LDAP

Condition d'organisation

Utilisez les utilisateurs existants définis dans le serveur LDAP d'organisation. De plus, le portail d'organisation permet de se connecter et d'accéder à CA Business Service Insight à l'aide des fonctionnalités de connexion silencieuse de CA Business Service Insight pour les portails Single Sign On (SSO).

Définissez un script de conversion Visual Basic (VB) pour la création automatique des utilisateurs dans le système CA Business Service Insight (synchronisation LDAP), le script de conversion permet de se connecter au serveur LDAP d'organisation et d'en extraire la liste d'utilisateurs. Les méthodes de package d'outils CA Business Service Insight sont utilisées pour la création des utilisateurs, groupes et rôles.

Exemple de code VB de connexion au serveur LDAP

        Dim ResultFields() As String = {"securityEquals", "cn"}
