Azure DNS tutorial incorrectly defines azure.json property for "Managed identity using Workload Identity"

[EvanSchallerer]

What happened:
I followed the Azure DNS tutorial to configure external-dns using the Managed identity using Workload Identity
section. external-dns would fail with an Entra error AADSTS700016 stating that the client ID may be misconfigured.

What you expected to happen:
external-dns does not fail with an error after following the tutorial.

How to reproduce it (as minimally and precisely as possible):
Follow the Azure DNS tutorial to configure external-dns using the Managed identity using Workload Identity
section.

Anything else we need to know?:
The code for configuring external dns configurations uses the clientID configuration which is resolved from aadClientId in the azure.json configuration file:

external-dns/provider/azure/config.go

Line 121 in 709f3f4

ClientID: cfg.ClientID,

The documentation tells you to use the userAssignedIdentityID, but this is only used for the "Managed identity using AAD Pod Identities" section:

external-dns/provider/azure/config.go

Line 139 in 709f3f4

msiOpt.ID = azidentity.ClientID(cfg.UserAssignedIdentityID)

Environment:

• External-DNS version (use external-dns --version): 1.15.0
• DNS provider: Azure
• Others:
