The user authentication failed! Re-Authenticating due to expired token after 12 hours in Dynamics 365

  • 1.  The user authentication failed! Re-Authenticating due to expired token after 12 hours in Dynamics 365

    Hi,

    we are using WCF service which connects to Microsoft dynamic 365 Version 1612(8.2.23.16) on premise. we are using simplified connection as below and we are using two cached connections as we are fetching data from two dynamic servers.

    The .Net framework is 4.6.2

    The references are below 

    <package id="Microsoft.CrmSdk.CoreAssemblies" version="9.0.2.34" targetFramework="net462" />
    <package id="Microsoft.CrmSdk.Deployment" version="9.0.2.34" targetFramework="net462" />
    <package id="Microsoft.CrmSdk.Workflow" version="9.0.2.34" targetFramework="net462" />
    <package id="Microsoft.CrmSdk.XrmTooling.CoreAssembly" version="9.1.0.79" targetFramework="net462" />
    <package id="Microsoft.IdentityModel.Clients.ActiveDirectory" version="5.2.9" targetFramework="net462" />

    The service works great for about 12 hours only, but after that we are getting an error as ' The user authentication failed! ' and we notice the below in the CRM logs, the security token expires. 

    Microsoft.Xrm.Tooling.Connector.CrmServiceClient Information: 8 : Validation of CRM Connection Complete, total duration: 00:00:06.6172066

    Microsoft.Xrm.Tooling.Connector.CrmServiceClient Warning: 4 : Re-Authenticating due to expired token @ 05/31/2021 07:19:18

    we have used the below coding

    In the webconfig file

      <add name="con1" connectionString="Url=**url**/Orgname;  Domain=domainname;    Username=domainname\***username***; Password=****; AuthType=Office365; RequireNewInstance=True;" />

      <add name="con2" connectionString="Url=**url**/Orgname;  Domain=domainname;    Username=domainname\***username***; Password=****; AuthType=Office365; RequireNewInstance=True;" />

     public OrganizationServiceProxy service;

     var client = CrmServiceClientCache.GetConn(ConfigurationManager.ConnectionStrings["con1"].ConnectionString);
     service = EASclient.OrganizationServiceProxy;

    public static CrmServiceClient Get(string connectionString)
    {
    if (_internalCache.ContainsKey(connectionString)
    && _internalCache[connectionString] != null
    && _internalCache[connectionString].IsReady)
    {
    return _internalCache[connectionString];
    }
    else
    {
    lock (_objLock)
    {
    if (!_internalCache.ContainsKey(connectionString)
    || _internalCache[connectionString] == null
    || !_internalCache[connectionString].IsReady)
    {
    ServicePointManager.SecurityProtocol |= SecurityProtocolType.Tls12;

    CrmServiceClient.MaxConnectionTimeout = new TimeSpan(0, 0, Convert.ToInt32(ConfigurationManager.AppSettings["CrmServiceClientTimeout"]));
    CrmServiceClient crmClient = new CrmServiceClient(connectionString);
    if (crmClient.IsReady)
    {
    _internalCache[connectionString] = crmClient ;
    }
    else
    {
    if (crmClient.LastCrmException != null)
    throw crmClient.LastCrmException;

    throw new InvalidOperationException(crmClient.LastCrmError);
    }
    }
    return _internalCache[connectionString];
    }
    }
    }

    Why would the security token not renewed automatically. We are looking of the support to get this problem resolved.
