ImportExport Service with ADFS

Using the ImportExport service with ADFS authentication is quite straight forward, if we use the Basic Authenticator. This one exposes a Basic authentication scheme, while communicating with the ADFS server in the background. Once a user is successfully authenticated, it creates a Thread and HttpContext security contexts, so that the following modules in the .NET request processing pipeline execute in the new security context.

As such, our client can define a Basic auth security using HTTPS transport and it will be able to connect to the service. This is the same mechanism the Content Porter application is using (i.e. Basic auth).


The .NET Console application I use as test client uses generated service proxy classes. The configuration presented below defines the endpoint to connect to and a simple HTTPS Basic auth transport.

      <binding name="basicHttp">
        <security mode="Transport">
          <transport clientCredentialType="Basic"/>

    <endpoint address="https://web85.playground/webservices/ImportExportService201601.svc/basicHttp"
      binding="basicHttpBinding" bindingConfiguration="basicHttp"
      contract="MyImportExportService.IImportExportService" name="basicHttp" />

Client Code

The client code creates an ImportExportServiceClient which uses the endpoint basicHttp defined in the .config file.

The communication is encrypted using HTTPS and credentials are sent inside the encrypted channel using Basic auth. The HTTP module Basic Authenticator handles the ADFS authentication and tokens and creates the right HttpContext and Thread security principals, so that by the time the request reaches the ImportExport service, it is already authenticated.

public Example()
    Console.WriteLine("ImportExport Example");

    using (var service = new ImportExportServiceClient("basicHttp"))
        service.ClientCredentials.UserName.UserName = username;
        service.ClientCredentials.UserName.Password = password;

        Console.WriteLine("Test Connection: {0}", service.TestConnection());

Content Delivery Monitoring in AWS with CloudWatch

This post describes a way of monitoring a Tridion 9 combined Deployer by sending the health checks into a custom metric in CloudWatch in AWS. The same approach can also be used for other Content Delivery services. Once the metric is available in CloudWatch, we can create alarms in case the service errors out or becomes unresponsive. The overall architecture is as follows: Content Delivery service sends heartbeat (or exposes HTTP endpoint) for monitoring Monitoring Agent checks heartbeat (or HTTP health check) regularly and stores health state AWS lambda function: runs regularly reads the health state from Monitoring Agent pushes custom metrics into CloudWatch I am running the Deployer ( installation docs ) and Monitoring Agent ( installation docs ) on a t2.medium EC2 instance running CentOS on which I also installed the Systems Manager Agent (SSM Agent) ( installation docs ). In my case I have a combined Deployer that I want to monitor. This consists of an Endpoint and a

Running sp_updatestats on AWS RDS database

Part of the maintenance tasks that I perform on a MSSQL Content Manager database is to run stored procedure sp_updatestats . exec sp_updatestats However, that is not supported on an AWS RDS instance. The error message below indicates that only the sa  account can perform this: Msg 15247 , Level 16 , State 1 , Procedure sp_updatestats, Line 15 [Batch Start Line 0 ] User does not have permission to perform this action. Instead there are several posts that suggest using UPDATE STATISTICS instead: I stumbled upon the following post from 2008 (!!!), , which describes a way to wrap the call to sp_updatestats and execute it under a different user: create procedure dbo.sp_updstats with execute as 'dbo' as

Event System to Create Mapped Structure Groups for Binary Publish

As a continuation of last week's Publish Binaries to Mapped Structure Group , this week's TBB is in fact the Event System part of that solution. Make sure you do check out the previous post first, which explains why and what this Event System does. To reiterate, the Event System intercepts a Multimedia Component save, take its Folder path and create a 1-to-1 mapping of Structure Groups. The original code was written, again, by my colleague Eric Huiza : [ TcmExtension ( "MyEvents" )] public class EventsManager  : TcmExtension {     private Configuration configuration;     private readonly Regex SAFE_DIRNAME_REGEX = new Regex ( @"[\W_]+" );     public EventsManager() {         ExeConfigurationFileMap fileMap = new ExeConfigurationFileMap ();         fileMap.ExeConfigFilename = Path .GetDirectoryName( Assembly .GetExecutingAssembly().Location) + "\\EventSystem.config" ;         configuration = ConfigurationManager
