    The error you’re seeing in Microsoft Dynamics 365:
     
    CrmException: The current organization id could not be determined
     
    combined with very slow login (~40 seconds) usually indicates a configuration or authentication resolution problem, not a simple IIS error.
    This issue typically occurs when CRM cannot resolve the organization context during the request pipeline.
    Most Common Causes in Dynamics 365 On-Prem 9.1

    Incorrect CRM Deployment URL Binding (Very Common)
     
    Your organization URL is:
     
    https://192.168.7.181/test-01
     
    But Dynamics expects access using the server hostname, not the IP.
     
    Example:
    https://D365.test.local/test-01
     
    CRM resolves the organization using host headers + deployment configuration.
    Using an IP address often breaks organization resolution.
     
    Fix
    Avoid IP-based URLs.
     
    CRM Website Authentication Configuration
    Verify IIS authentication settings.
     
    CRMAppPool Identity Problem
     
    Your log shows:
    Process account: test\administrator
    This is not recommended.
     
    CRMAppPool should run under:
    Network Service
    or a dedicated CRM service account.
     
    Missing Organization Mapping in Deployment Manager
    Open Microsoft Dynamics 365 Deployment Manager
    Check:
    Organizations
     → test-01
    Verify:
    • Organization is Enabled
    • State = Ready
    If not:
    • Right Click → Enable

    DNS Resolution Delay (Causes 40s Login Delay)
    The 40 second delay strongly suggests DNS resolution issues.
    Test from the CRM server:
    • ping D365.test.local
    • nslookup D365.test.local
    Also test reverse lookup:
    • nslookup 192.168.7.181
    If reverse DNS fails → authentication delays occur.
    Fix by adding DNS A and PTR records.
     
    SPN (Kerberos) Issues
    If using Windows Authentication:
    Check SPN:
    • setspn -L D365
    • If CRMAppPool uses domain account:
    • setspn -S HTTP/D365.test.local test\crmservice
     
    CRM Cache Issue
    Sometimes CRM cache causes this error.
    Clear CRM cache:
    C:\Program Files\Dynamics 365\CRMWeb\Server\bin\assembly
    Restart:
    • IISRESET
