Two efficiency issues raised for the multi-subscription Azure flow: 1. Inefficient parallel subscription checking. The fan-out ran a full 'az login --service-principal' plus allocated a private AZURE_CONFIG_DIR for every subscription (2N subprocesses / N temp dirs). All connected subscriptions share one service principal and the SP login is tenant-scoped, so we now authenticate ONCE into a single shared config dir and fan the subscription-pinned (--subscription) commands across it (N+1 subprocesses / 1 temp dir). Sharing the dir is safe because login happens up front and the pinned commands never mutate the CLI's active subscription. 2. Fanning out to all subscriptions when a specific one was requested. Rather than adding a name->id resolver in code, warn in the Azure RCA skill that the fan-out is expensive and instruct the agent to pass account_id from the first call whenever the target subscription is already known/named, and to omit it only when the owning subscription is genuinely unknown.

Document the frontendImage exception in digest-pinned upgrades.
--reuse-values retains frontendImage.tag. When that tag is nonempty, the deployment intentionally uses the configured frontendImage and does not call aurora.image; image.digests.frontend applies only to the fallback image. The documented upgrade can therefore retain an older custom frontend tag. State that users must clear frontendImage when they want the release frontend digest. Do not give the digest precedence over this explicit custom-image override.

Reject ambiguous subscription display names.
This loop returns the first connected subscription with the requested display name. If two connected subscriptions share that name, ARM response order determines the selected subscription. The command can then run against the wrong subscription.
Collect all matching IDs. Return an ID only when exactly one match exists. Otherwise, require the subscription GUID.

Override an existing image.tag in this upgrade flow.
--reuse-values retains every non-empty prior image.tag, not only "latest". The helper then uses that old tag instead of Chart.AppVersion. Users following the previously documented sha-<short> flow can upgrade the chart but continue to run the old images. Add --set-string image.tag=<X.Y.Z> to this command, or instruct users to remove the stored key before this upgrade.

Target later Azure calls to the discovered subscription.
The guidance says that omitting account_id performs a command across every connected subscription. The vm list, group list, and network nsg list examples omit it. If these are follow-up checks after the target subscription is known, add account_id='SUBSCRIPTION_ID'; otherwise, mark them explicitly as intentional all-subscription searches.

Azure CLI concurrent access shared AZURE_CONFIG_DIR lock failure official documentation issue 20273
💡 Result:
<search_synthesis>
Azure CLI issue 20273 relates to "Permission denied" errors on the msal_token_cache.bin.lockfile when multiple Azure CLI instances attempt to access the same configuration directory (AZURE_CONFIG_DIR) simultaneously [1][2]. This was caused by overly aggressive file locking in the msal-extensions library, which required a lock even for read operations [1]. This issue has been resolved in subsequent updates to the msal-extensions library [3][1]. To address this or similar concurrency issues: 1. Update Azure CLI: Ensure you are using the latest version of the Azure CLI, which includes updated dependencies that handle concurrent read-write access more efficiently [3][1]. 2. Use AZURE_CONFIG_DIR for Isolation: In environments with high concurrency (such as CI/CD build agents), it is a best practice to set the AZURE_CONFIG_DIR environment variable to a unique, task-specific directory for each concurrent process [4][5]. This prevents multiple processes from contending for the same credential cache files [4][6]. Example of setting a unique directory in a shell environment: export AZURE_CONFIG_DIR=$(mktemp -d) By isolating the configuration directory, you avoid race conditions and file lock failures entirely [7].

Pin Azure CLI or isolate each worker’s config. The fan-out passes the same AZURE_CONFIG_DIR to concurrent az processes. Azure CLI issue #20273 documents token-cache lock failures during concurrent access, and the fix depends on the Azure CLI/MSAL version. The Dockerfiles install Azure CLI through a moving URL without pinning that version. Pin a version with the concurrency fix; otherwise give each worker its own copied config directory or serialize the commands.

Exercise the Azure authentication failure branch.
fail_setup=True returns before terminal_run evaluates auth_result.returncode, so this test does not cover a failed az login. Make setup succeed, return a nonzero result for the login argv, and assert that no subscription command runs and the shared directory is removed by cleanup.

az account commands operate at the tenant/management plane (e.g. 'az account list' enumerates every subscription) and reject the --subscription flag with 'unrecognized arguments'. Skip pinning them, same as 'az graph'. Co-authored-by: Cursor <cursoragent@cursor.com>

Do not fan out tenant-scoped Azure commands.
When neither account_id nor selected_project_id is set and multiple Azure connections exist, _azure_can_fan_out accepts az graph and az account, so the multi-subscription path runs each tenant-scoped command once per connection. _apply_azure_subscription leaves both commands unchanged, which repeats the operation and adds unnecessary subprocesses.
Exclude these command classes from _azure_can_fan_out, or execute them once outside the subscription pool.

This comment is now out of date with the fan-out you changed below. It says a shared dir would race and that the fan-out removes the dir per subscription. After this PR the fan-out calls this once with subscription_id=None, shares that one dir across every worker, and removes it once in its own finally (lines 1499-1502). Could you reword it to match? Something like: "The single-subscription path gets its own dir; the multi-subscription fan-out authenticates once, shares the dir across its workers (commands are pinned with --subscription so nothing mutates the active-subscription state), and removes it in its own finally."
| # setup_azure_environment_isolated mkdtemps an AZURE_CONFIG_DIR per call. The | ||
| # fan-out path removes its own per subscription, but the single-subscription | ||
| # path returns from ~20 places, so clean up here where every path converges. | ||
| # Without this the dirs accumulate in /tmp for the life of the worker. |

Same staleness here: "the fan-out path removes its own per subscription" is no longer true, it removes one shared dir once. Just drop "per subscription".
* Reuse one az login per Azure credential set across cloud_exec commands * Block commands that read the Azure CLI login cache or its credential files * Test Azure login reuse in the cache module and the multi-subscription fan-out * Add AZURE_LOGIN_CACHE_IDLE_SECONDS to compose, Helm values and env docs * Check every word for CLI-local-state commands, not only the first three * Split the Azure fan-out into helpers and simplify test assertions * Make the Azure login cache idle window a module constant and inline the pod-isolation check

Summary
Fixes the two efficiency issues raised in today's meeting about the new Azure multi-subscription update.
1. Inefficient parallel checking of subscriptions (code fix)
Before: the fan-out (
_cloud_exec_azure_multi_subscriptioninserver/chat/backend/agent/tools/cloud_exec_tool.py) ran a fullaz login --service-principaland allocated a privateAZURE_CONFIG_DIRper subscription — 2N subprocesses and N temp dirs for N subscriptions.Why that was wasteful: every connected subscription belongs to the same service principal, and an SP
az loginis tenant-scoped — one login already authenticates every subscription. (Discovery'sazure_asset_discoveryalready logs in once and queries many subscriptions.)After: authenticate once into a single shared
AZURE_CONFIG_DIR, then fan the per-subscription commands (each pinned with--subscription) across it. Cost drops from 2N → N+1 subprocesses and N → 1 temp dir. Safe because login completes up front and the pinned commands never mutate the CLI's active-subscription state.2. Don't check all subscriptions when a specific one was requested (guidance fix)
Rather than adding a name→id resolver in code (overfitting), this updates the Azure RCA skill (
server/chat/backend/agent/skills/rca/provider_azure.md) to:account_idfans out across every subscription and is expensive,account_id='SUBSCRIPTION_ID'from the first call whenever the target subscription is already known or named by the user,account_idonly when the owning subscription is genuinely unknown.This keeps the mechanism simple and steers the agent away from the "fan out to all, then find the requested one" pattern.
Tests
Updated
server/tests/connectors/test_azure_multi_subscription.pyfor the single-login model:test_fanout_authenticates_once_and_pins_every_subscription— exactly oneaz login/ one shared config dir, every command still pinned to its subscription, secret still reachesazbyte-for-byte and never via a shell.test_fanout_cleans_up_its_shared_temp_dir,test_fanout_fails_closed_when_shared_login_fails,test_fanout_isolates_per_subscription_failures— updated for the single-login model.All 75 tests in the file pass locally.
