scope (RBAC writes). Wait ~3 minutes after first-time grants for AAD propagation before
|

running the tests.
|
||||
|
||||
### Per-scenario data-plane RBAC (manual, one time per agent)
|
||||
|
||||
The bootstrap script grants only `Azure AI User` on the Foundry project scope, which is what
|
||||
every hosted agent needs to receive inbound inference traffic. Scenarios that read from
|
||||
external data services need an additional grant on that service to the agent's managed
|
||||
identity. Today only the `azure-search-rag` scenario falls into this category.
|
||||
|
||||
For `it-azure-search-rag`, after the first bootstrap run, grant `Search Index Data Reader`
|
||||
on the Azure AI Search service to the agent's managed identity:
|
||||
|
||||
```powershell
|
||||
# 1. Get the agent MI principal id
|
||||
$tok = az account get-access-token --resource "https://ai.azure.com" --query accessToken -o tsv
|
||||

|
||||

|
||||
-Uri "<project-endpoint>/agents/it-azure-search-rag?api-version=v1"
|
||||
$mi = $agent.versions.latest.instance_identity.principal_id
|
||||
|
||||
# 2. Grant Search Index Data Reader on the search service
|
||||
az role assignment create `
|
||||
--assignee-object-id $mi `
|
||||
--assignee-principal-type ServicePrincipal `
|
||||
--role "Search Index Data Reader" `
|
||||
--scope "/subscriptions/<sub>/resourceGroups/<rg>/providers/Microsoft.Search/searchServices/<search-service>"
|
||||
```
|
||||
|
||||
Wait ~3 minutes after the grant for RBAC propagation before running the tests.
|
||||
|
||||
If the search service has `authOptions = apiKeyOnly` (default for older deployments), Entra
|
||||
auth will return 403 regardless of role assignments. Flip it to `aadOrApiKey` first:
|
||||
|
||||
```powershell
|
||||
az search service update -g <rg> -n <search-service> --auth-options aadOrApiKey --aad-auth-failure-mode http403
|
||||
```
|
||||
|
||||
### Azure AI Search index prerequisite (one time, out of band)
|
||||
|
||||
The `azure-search-rag` scenario assumes the index pointed at by `AZURE_SEARCH_INDEX_NAME` already
|
||||
exists with the schema and Contoso Outdoors content the test asserts against. See
|
||||
`dotnet/samples/04-hosting/FoundryHostedAgents/responses/Hosted-AzureSearchRag/README.md` for
|
||||
the schema and copy-pasteable provisioning snippet. Provisioning the index from your user
|
||||
identity needs `Search Index Data Contributor` on the search service scope. The search service
|
||||
itself is treated as pre-existing infrastructure shared with `python-sample-validation.yml`;
|
||||
no automated provisioning script ships in this repository.
|
||||
|
||||
### Required user/SP roles for delegating data-plane grants
|
||||
|
||||
To self-serve the `Search Index Data Reader` grant above, you need `User Access Administrator`
|
||||
(or `Owner`) on the search service scope. To create/seed the index from your own identity, you
|
||||
need `Search Index Data Contributor`. These are typically granted once per onboarded engineer
|
||||
and reused for every new IT scenario that needs Search.
