Hantera certifikatbaserade användare i azure confidential ledger

För certifikatbaserade användare är deras användar-ID fingeravtrycket för deras PEM-certifikat. Användare med administratörsbehörighet kan hantera användare av den konfidentiella transaktionsregistret. Tillgängliga roller är Läsare (skrivskyddad), Deltagare (läsa och skriva) och Administratör (läsa, skriva och hantera användare).

Följande klientbibliotek är tillgängliga för att hantera användare:

Logga in på Azure

Logga in på Azure med azure CLI az login-kommandot eller cmdleten Azure PowerShell Connect-AzAccount .

az login

Om CLI eller PowerShell kan öppna standardwebbläsaren kommer den att göra det och läsa in en Azure-inloggningssida. Annars går du till https://aka.ms/devicelogin och anger auktoriseringskoden som visas i terminalen.

Logga in med dina kontoautentiseringsuppgifter i webbläsaren om du uppmanas att göra det.

Hämta namnet på den konfidentiella transaktionsregistret och identitetstjänstens URI från Azure-portalen. det kommer att behövas för att skapa en klient för att hantera användarna. Bilden visar lämpliga egenskaper i Azure-portalen.
