Perfect, Thank you, I was unable to get it to work using RBAC but I switched to Vault access policy and set the permissions and it's worked perfectly!

hi folks,

so I have the same question, but reading your advice doesn't help me really.

I created the Key Vault, use RBAC, created a certificate successfully under

Microsoft.Web-AppServiceCertificates-Portal-0123456789

I am the owner of the Vault and certificate.

I assigned the user myself the role

Key Vault Administrator
Key Vault Secrets Officer

The Domain Access Verification by godaddy was successful "Domain Access Approval Completed".

The topic "3. Assign required roles to App Service Certificate service principals"

causes me headache. Don't know where or what to find. Maybe the GUI has changed as often at Microsoft (Azure).

It' a pain to read some old articles while "Microsoft Azure Trusted Signing" was meanwhile renamed to "Artifact Signing".

Many old Howto's don't really help.

Finally the popup "Save Key Vault Settings" (exactly like the one above) with the error

Failed to link certificate with the selected Key Vault

... Caller is not authorized to perform action on resource.

always rises. Even Copilot does not help, so I try it here

Meanwhile "App Service Certificates" shows my certificate with Status "Denied",

when starting some days before the status was "Pendingissuance"

So, I created a new certificate and get the same Popup error. Godaddy says success.

I'm totally stuck...
