Temp folder access issue while calling organisation service endpoint

ReportReport
Posted on by SA-17061454-0 2
I'm working with a dot net based web application that connects to two on-premises CRM (Dataverse) organizations (Org A and Org B) hosted on the same server. Im fetching data using API endpoint url. When connecting with User B, I can access Org A consistently without issues, but accessing Org B intermittently fails, especially after switching between organizations. The problem disappears if I manually clear the contents of C:\Windows\TEMP\Cds.ODataMetadata, suggesting a metadata cache conflict or permissions issue. Notably, User A (an admin) can access both orgs without issue. My goal is to access both Org A and Org B using User B reliably from the same application. Has anyone experienced metadata caching issues across multiple orgs and users? Is there a supported way to isolate or disable disk-based caching to avoid these conflicts?
 
Is there any documentation that says my User B should have Read/Write access to Temp folder on CRM Web server?

Error: Access to the path 'C:\Windows\TEMP\Cds.ODataMetadata\a29799d665c4e51180d20050569b6a23.GetMetadata.1033.9.Minimal.3721460116.0.421361534.cache' is denied.

    Maybe consider using a service account for that, and grant the service account proper access right to the folder.

    I'm currently investigating the root cause of the issue, particularly why it's working fine in Org A and not(always) for Org B. If it were an access-related problem, I would expect it to fail consistently across all calls for both Org A and Org B, because the calling user is same and TEMP folder is also same.

    That said, I haven’t encountered this issue in my local environment over the past few days, so I’m unable to test whether granting access to the calling user would resolve it. My main concern is ensuring that this doesn’t occur in the production environment.
     
    P.S - By "clear," I mean manually clearing the temp folder by remotely logging into the server using a Windows admin account.

    Have you tried to grant User B the proper access of that folder ?
    When you say' manually clear the content..', by what kind of level access right ?
