Azure Key Vault is used to safeguard system critical data, such as keys, secrets and certificates that are part of your infrastructure core operations.
Key Vault access is managed through two interfaces: management plane – this dictates access to the Key Vault itself but not managing its content which is based on RBAC model, data plane – this enables granular control of keys/secrets/certificates, which relies on Access Policy.
This brings us nicely to Access Policies which is meat of this article. I have had to deal with a situation lately while applying access policy for a colleague while a restriction is imposed on my Azure AD account (see example below)
This would have limited access to my account (which is external) to AAD, which means I cant read or search AAD which is required when adding access policy via the GUI – Setting RBAC without access to AAD works (as an exception) if you know the full FQDN of the user you are adding.
The way around is to use PowerShell, but this requires a prerequisite which is the Azure AD object ID for the user you want to add, this can be achieved by adding them temporarily on management plane to access their user properties and copy object ID before deleting that rule.
Now to the command I used to apply that permission:
Key property here is the BypassObjectIdValidation, if the Object ID exists in AAD then it will be linked and the user will have their access policy applied to Azure Key Vault.
