Gérer des utilisateurs basés sur des certificats dans le registre confidentiel Azure

  • Article

Pour les utilisateurs basés sur des certificats, leur ID d’utilisateur est l’empreinte digitale de leur certificat PEM. Les utilisateurs disposant de privilèges d’administrateur peuvent gérer les utilisateurs du registre confidentiel. Les rôles disponibles sont Lecteur (en lecture seule), Contributeur (lecture et écriture) et Administrateur (lecture, écriture et gestion des utilisateurs).

Les bibliothèques client suivantes sont disponibles pour la gestion des utilisateurs :

Connexion à Azure

Connectez-vous à Azure à l’aide de la commande Azure CLI az login ou de la cmdlet Azure PowerShell Connect-AzAccount.

az login

Si Azure CLI ou PowerShell peut ouvrir votre navigateur par défaut, il le fait et charge une page de connexion Azure. Sinon, visitez https://aka.ms/devicelogin et entrez le code d’autorisation affiché dans votre terminal.

Si on vous le demande, connectez-vous ensuite avec les informations d’identification de votre compte dans le navigateur.

Obtenez l’URI du service d’identité et le nom du registre confidentiel à partir du Portail Azure, car ils sont nécessaires pour la création d’un client afin de gérer les utilisateurs. Cette image montre les propriétés appropriées dans le Portail Azure.

Remplacez les instances de contoso et https://contoso.confidential-ledger.azure.com dans les extraits de code suivants par les valeurs respectives du Portail Azure.
