Adlsdk-status-auth-pending 4 ❲SECURE — Series❳

The pending auth is often transient. Implement retries with exponential backoff (e.g., 3 retries, starting 1s delay).

Python example:

from azure.storage.filedatalake import DataLakeServiceClient
from azure.identity import DefaultAzureCredential
from time import sleep
credential = DefaultAzureCredential()
for attempt in range(4):
try:
client = DataLakeServiceClient(account_url="https://<account>.dfs.core.windows.net", credential=credential)
client.get_file_system_client("myfs").get_file_client("test.txt").get_file_properties()
break
except Exception as e:
if "AUTH_PENDING" in str(e) and attempt < 3:
sleep(2 ** attempt)
continue
raise

In a production stream processing job using ADL Gen2, we observed the following log sequence:

10:32:01.123 [main] INFO  - Initiating token refresh for tenant "adls-tenant-4"
10:32:01.456 [netty-io-2] DEBUG - Received OAuth2 response (cached token expired)
10:32:01.457 [netty-io-2] DEBUG - Setting AUTH_PENDING state: 4
10:32:01.458 [main] WARN  - Thread blocked: adlsdk-status-auth-pending 4
10:33:01.459 [main] ERROR - Timeout after 60s - no callback invoked.

Key Insight: The network layer succeeded (the token was actually fetched). The failure occurred when the callback tried to notify() a CountDownLatch that had already been destroyed due to a premature timeout handler in the caller’s code.

| Code | Status | Action | |------|--------|--------| | 4 | AUTH_PENDING | 1. Verify RBAC/ACL → 2. Wait 5 mins after changes → 3. Refresh token cache → 4. Add retry logic | adlsdk-status-auth-pending 4

Most common root cause: Role assignment or ACL change not yet propagated – wait 5–10 minutes.
Second most common: Wrong token scope – use https://storage.azure.com/.default.

The error code ADLSDK_STATUS_AUTH_PENDING 4 indicates that your

software has not yet been registered with the local licensing service. This typically happens when the software is launched before the installation and registration process is fully completed by the system. Recommended Solutions The pending auth is often transient

To resolve this issue, you can try the following steps according to official Autodesk Support Manually Register the Software : You may need to manually register the product using the AdskLicensingInstHelper.exe tool found in your Autodesk Shared folder. Restart Autodesk Services : Ensure the Autodesk Desktop Licensing Service

is running in the Windows Services menu. Set it to 'Automatic' and restart it if it is stopped. Update Licensing Components : Download and install the latest updates for the Autodesk Desktop Licensing Service Autodesk Identity Manager (for 2024 versions and newer) or the Single Sign On Component (for 2020-2023 versions) from your Autodesk Account Check Date and Time

: Verify that your system's date and time are synchronized automatically. Discrepancies can prevent license verification. Reinstall the Licensing Service : If the above fails, uninstall the service via the uninstall.exe In a production stream processing job using ADL

C:\Program Files (x86)\Common Files\Autodesk Shared\AdskLicensing , then download and reinstall the latest version. Are you using a Student Edition or a standard Commercial Subscription for your software?
