Walkthrough: Setting up Team Foundation Server with Secure Sockets Layer (SSL) and an ISAPI Filter

The following walkthrough describes one process for requesting, issuing, and assigning certificates that are used for Secure Sockets Layer (SSL) connections in Visual Studio Team System Team Foundation Server, configuring Basic and/or Digest authentication, and configuring an ISAPI filter. In order to support external connections to your Team Foundation Server deployments, you must configure Internet Information Services (IIS) to enable Basic and/or Digest authentication. Additionally, you must configure an Internet Server Application Programming Interface (ISAPI) filter.

Note:
You do not have to configure an ISAPI filter in order to enable HTTPS/SSL. This walkthrough provides guidance for configuring all of the following activities, but you can configure your own Team Foundation Server deployment differently.

Throughout this walkthrough, you will accomplish the following activities:

Create a certificate request for Team Foundation Web sites.
Issue the certificate request and create the binary certificate file.
Install and assign the certificate.
Configure the Team Foundation Server for HTTPS and SSL.
Install the certificate on client computers.
Test the certificate.

Note:
The procedures in this walkthrough do not require the clients to use HTTPS and SSL only when they connect to Team Foundation. For more information about how to restrict connections to HTTPS and SSL only, see Walkthrough: Setting up Team Foundation Server to Require HTTPS and Secure Sockets Layer (SSL).

Prerequisites

To complete this walkthrough:

The logical components that compose the data tier of Team Foundation and the application tier of Team Foundation Server must be installed and operational. This walkthrough refers to the server or servers that are running the logical components that compose the application tier of Team Foundation as the application-tier server for Team Foundation. This walkthrough also refers to the server or servers that are running the logical components that compose the data tier of Team Foundation as the data-tier server for Team Foundation. Depending on your deployment configuration, these servers might be the same physical server or one or more different physical servers. For more information, see the installation guide for Team Foundation. You can download the most recent version of this guide from the Microsoft Download Center (http://go.microsoft.com/fwlink/?linkid=79226).
You must have a certification authority (CA) available to issue certificates. This walkthrough assumes that you are using Microsoft Certificate Services as your CA. If you do not have a certification authority, you can install Microsoft Certificate Services and configure a certification authority. For more information, see the Microsoft Web site (http://go.microsoft.com/fwlink/?LinkId=70929).

Required Permissions

To complete this procedure, you must be a member of the Administrators group on the application-tier and data-tier servers for Team Foundation and a member of the Team Foundation Administrators group. To configure a build agent for SSL connections, you must be a member of the Administrators group on the build computer. For more information about permissions, see Team Foundation Server Permissions.

Assumptions

This walkthrough demonstrates a specific deployment configuration. If your deployment differs from this configuration, some of the steps in this walkthrough will not match those steps required to configure your deployment. For more information about steps for different versions of SharePoint Products and Technologies, SQL Server, Windows Server, and Internet Explorer, consult the Help for the appropriate versions of those systems.

This walkthrough makes the following assumptions about the starting configuration of the deployment for which you want to configure HTTPS and SSL:

The servers in the deployment are running Windows Server 2003 and IIS 6.0.
The deployment uses SQL Server 2005 and Windows SharePoint Services 3.0.
The client computers in the deployment are running Windows XP and Internet Explorer 6.0.

Both Windows SharePoint Services 3.0 and Certificate Services are installed and configured on the application-tier server for Team Foundation.

Note:
To follow best practices for security, you should install Certificate Services on the application tier only for demonstration or test purposes. In a production environment, you should always install Certificate Services on a separate server.

The data-tier and application-tier servers for Team Foundation have been installed and deployed in a secure environment and configured according to best practices for security.
To configure a build agent for SSL connections, the following conditions must be true:
- Team Foundation Build and Team Explorer must be installed and operational.
- A certificate must have been issued for the build agent.
- Windows Support Tools must be installed on the build computer so that you can associate a certificate with the IP address and port. For more information, see "Windows Support Tools" (http://go.microsoft.com/fwlink/?LinkId=93827).

Installing Microsoft Certificate Services

This walkthrough uses Microsoft Certificate Services as the certification authority (CA) for issuing certificates. For convenience in this walkthrough, Certificate Services is installed on the Team Foundation application-tier server, but you can choose your own certification authority software and deployment configuration as best suits your business needs. For security, you should consider isolating your root certification authority when you deploy Certificate Services in a production deployment. Physical isolation of the CA server, in a facility that is available only to security administrators, can significantly reduce the risk of tampering. For more information about Certificate Services features and best practices, see the Microsoft Web site (http://go.microsoft.com/fwlink/?LinkId=70929).

Caution:
After you install Certificate Services, you cannot change the name of the computer or the domain of which the computer is a member. If you change the computer name or the domain, you invalidate the certificate that the certification authority (CA) issued.

To install Certificate Services on Windows Server 2003

Click Start, click Control Panel, and then click Add or Remove Programs.
Click Add/Remove Windows Components.
In the Windows Components Wizard, click Certificate Services in the Components list.
Review the text in the message box, and then click Yes.
Click Next to start the installation.
On the CA Type page, select Stand-alone root CA, and then click Next.
On the CA Identifying Information page, in Common name for this CA, type the name of the computer.
In Validity period, change the duration for the certificate to six (6) months, and then click Next.
On the Certificate Database Settings page, click Next without making any changes.
A message box appears that shows that IIS must be stopped.
In the message box, click Yes.
The Configuring Components page appears.
If a message box appears with information about Active Server Pages (ASP), click Yes.
Click Finish.

Creating a Certificate Request for Team Foundation Server Web Sites

On the application-tier computer, you must create a certificate request for Team Foundation using Internet Information Services (IIS) Manager.

Note:
These steps are specific to Windows Server 2003 and IIS 6.0. If your deployment is using Windows Server 2008 and IIS 7.0, you must follow a different set of steps. For more information, see this page on the Microsoft Web site: IIS 7.0: Internet Information Services (IIS) Manager.

Configuring the ISAPI Filter

You must edit the ISAPI initialization file that is in the same directory as the AuthenticationFilter.dll file. You must also add the ISAPI filter to the registry.

Note:
You might not need to complete this procedure if you are configuring HTTPS and SSL for intranet access only and do not intend to permit Internet access to the server.

To configure the ISAPI Filter

On the application-tier server for Team Foundation, click Start, click Programs, click Accessories, and then click Notepad.
In Notepad, open the AuthenticationFilter.ini file that is in the same directory as AuthenticationFilter.dll.
By default, this directory is Drive:\Program Files\Microsoft Visual Studio 2008 Team Foundation Server\Tools.

Modify the .ini file in the following ways:

ProxyAddress is the IP address from which external network traffic to Team Foundation Server will appear to originate (usually a router) for which you want to require HTTPS/SSL with Basic or Digest authentication.
SubnetMask is the IP address/subnet mask pair or pairs for which you do not want to enforce Digest or Basic authentication.

Important Note:
If you add the ProxyIPList key to the file, the SubnetList key and its values will be ignored. For more information, see Team Foundation Server, Basic Authentication, and Digest Authentication.

Note:
You can specify more than one value for either ProxyAddress or IP/SubnetMask, but you must delimit multiple values with semicolons.

[config]

RequireSecurePort=false

ProxyIPList= ProxyAddress

SubnetList= SubnetMask

Save this file as AuthenticationFilter.ini in the same directory as AuthenticationFilter.dll:

Drive :\Program Files\Microsoft Visual Studio 2008 Team Foundation Server\Tools

Important Note:
Do not change the directory of either the AuthenticationFilter.ini file or the AuthenticationFilter.dll file. If you change either of these directories, you will more likely have problems when you perform maintenance or upgrade your deployment.

To configure a firewall to allow for network traffic on the SSL ports that are used by Team Foundation Server

See your firewall product documentation to determine the steps that are required to allow for network traffic on the SSL ports you specified for the default Web site, the Team Foundation Web site, and the SharePoint Central Administration Web site.

Configuring SharePoint Products and Technologies to Allow Alternate Mappings

For team project portal mappings and administration mappings to work correctly, you must configure SharePoint Products and Technologies to allow for alternate mappings for traffic on the SSL ports you specified in IIS for the default Web site, the Web site for Team Foundation Server, and the SharePoint Central Administration Web site.

Note:
The procedures for configuring SharePoint Products and Technologies might vary depending on your operating system and on the product version you are using. The following procedure is specific to Windows SharePoint Services 3.0. For more information, see Connecting to a Server That Is Running SharePoint Products and Technologies.

To configure Windows SharePoint Services 3.0 to allow alternate access mappings to team project Web sites

On the server that is running Windows SharePoint Services 3.0, open Internet Explorer, and navigate to https://SharePointServerName:AdministrationPort.

Important Note:
You configured the administration port for SharePoint Products and Technologies in the procedure "To set up HTTPS for SharePoint Central Administration and Require SSL" previously in this walkthrough. You must navigate to the Central Administration site using the port that you assigned in that procedure. Until this procedure has been completed, you cannot access the Central Administration tool from the Start menu.

Important Note:

To update team project sites for SQL Report Server

On the application-tier server for Team Foundation, open a Command Prompt window, and change directories to Drive:\%ProgramFiles%\Microsoft Visual Studio 2008 Team Foundation Server\Tools.
At the command prompt, type the following command, and replace these strings:
- SharePointSite is the new uniform resource indicator (URI) of the site collection of SharePoint Products and Technologies.
- Reports is the new URI for SQL Server Reporting Services.
- ReportServer is the new URI for the ReportsService.asmx Web service.
  TfsConfigWss ConfigureReporting /SharepointSitesUri: SharePointSite /ReportsUri:Reports /ReportServerUri:ReportServer

Updating Team Foundation Server Configuration Information

Follow these steps to update configuration information with the https URL values for the Windows SharePoint Services and Reporting Services Web sites.

To update configuration information for Team Foundation Server

On the Team Foundation application-tier server, open a Command Prompt window, and change directories to Drive:\%ProgramFiles%\Microsoft Visual Studio 2008 Team Foundation Server\Tools.

At the command prompt, type the following command, and replace these strings:

BaseServerURL is the new URI for the Web server for the Team Foundation application-tier server.
BaseSiteURL is the new URI for the default Web site for the application-tier server.
SharePointSite is the new URI for the SharePoint Products and Technologies site collection.
SharePointAdministration is the new URI for the SharePoint Central Administration Web site.
Reports is the new URI for SQL Server Reporting Services.

ReportServer is the new URI for the ReportsService.asmx Web service.

Important Note:
If you have installed SP1 for Visual Studio Team System 2008 Team Foundation Server, the /ReportServer parameter will not function correctly. For more information about this problem and its resolution, see this article on the Microsoft Web site: Team Foundation Server 2008 SP1 TfsAdminUtil.exe 'ConfigureConnections' fails to properly set ReportServerUri.

TfsAdminUtil ConfigureConnections /ATUri: BaseServerURL /SharepointUri:BaseSiteURL /SharepointSitesUri:SharePointSite /SharepointAdminUri:SharePointAdministration /ReportsUri:Reports /ReportServerUri:ReportServer

Note:
If you are using a named instance, you will need to specify the named instance as part of the values for Reports and ReportServer. Do not eliminate or change the name of the named instance.

For example, if you specified port 443 for the Team Foundation Web SSL site port value, 1443 for the default Web site SSL port value in IIS, and 2443 for the SharePoint Central Administration port value, and your application-tier server was named Contoso1, you would modify the values as follows:

TfsAdminUtil ConfigureConnections /ATUri:https://Contoso1:443 /SharepointUri:https://Contoso1:1443 /SharepointSitesUri:https://Contoso1:1443/Sites /SharepointAdminUri:https://Contoso1:2443 /ReportsUri:https://Contoso1:1443/Reports /ReportServerUri:https://Contoso1:1443/ReportServer

Note:
The ConfigureConnections command has several additional options, such as updating the public Web address used in e-mail alerts. For more information, see ConfigureConnections Command.

Installing the Certificate on Build Computers

If you installed Build Services on one or more servers, you must install the certificate on each of those servers.

Note:
To perform builds over SSL, you must install the certificate in the trusted root store on both the build computer for the account on which the build service is running and the computer that initiates the build. Additionally, the build server must have its own certificate. You cannot use the same certificate on the build server as the certificate that you use on the server that is running Team Foundation Server.

Configuring a Build Agent for SSL Connections

To configure a build agent for SSL connections, you must configure an HTTPS certificate for each combination of IP address and port. If all build agents share the same port on the build computer, you must configure only a single certificate. If you run more than one build agent on more than one port, you must configure a certificate for each port.

You configure a build agent to require SSL by performing the following tasks in sequence:

Create and configure the build agent to require HTTPS.
Stop the Visual Studio Team Foundation Build service.
Modify the build service configuration to require HTTPS.

Associate a certificate with the IP address and port.

Important Note:
You cannot use the same certificate on the build agent that you used on the server that is running Team Foundation Server. The build agent must have its own certificate. You must install the certificate in the trusted root store on both the build computer for the account on which the build service is running and the computer that initiates the build.

Configure the port and protocol for the build agent.
Restart the Visual Studio Team Foundation Build service.
Verify the SSL configuration.

To configure the build agent to require HTTPS

Open the Manage Build Agents dialog box, and select the Require Secure Channel (HTTPS) check box.
For more information, see How to: Create and Manage Build Agents.

The file opens in the XML editor for Visual Studio.
In the <appSettings> section, change the value of the RequireSecureChannel key to "true". For example, change the key definition to the following string:
```
<add key="RequireSecureChannel" value="true" />
```
Save your changes, and close the file.

To associate an SSL certificate to an IP address and port number

Log on to the build computer by using an account that is a member of the Administrators group on that computer.

Use the Certificates snap-in to find an X.509 certificate that has an intended purpose of server authentication.

Important Note:
You cannot use the same certificate on the build computer as the certificate that you use on the server that is running Team Foundation Server unless the build computer is installed on the same server that is running the application tier for Team Foundation.

For more information, see "How To: Retrieve the Thumbprint of a Certificate" (http://go.microsoft.com/fwlink/?LinkId=93828).

Copy the thumbprint of the certificate into a text editor, such as Notepad.
Remove all spaces between the hexadecimal characters.
You can perform this task by using the text editor's find-and-replace feature to replace each space with a null character.
On the build computer, click Start, click All Programs, click Windows Support Tools, and then click Command Prompt.
Run the HttpCfg.exe tool in "set" mode on the SSL store to bind the certificate to a port number. The tool uses the thumbprint to identify the certificate, as shown in the following example:
```
httpcfg set ssl /i 0.0.0.0:9191 /h ThumbprintWithNoSpaces
```
The /i parameter has the syntax of IPAddress:Port and instructs the tool to set the certificate to port 9191 of the build computer. The IP address 0.0.0.0 reserves all computer addresses for simplicity. If you need additional precision, specify the exact IP address on which the agent service is published. The /h parameter specifies the thumbprint of the certificate.
If the client certificate must be negotiated, add the parameter/f 2 as shown in the following example:
```
httpcfg set ssl /i 0.0.0.0:9191 /h ThumbprintWithNoSpaces /f 2
```
For more information about the syntax of the HttpCfg.exe command, see "How To: Configure a Port with An SSL Certificate" (http://go.microsoft.com/fwlink/?LinkId=93829).

To configure the build agent port and protocol

At the command prompt, run wcfhttpconfig free PortNumber. The command statement should resemble the following string:
```
wcfhttpconfig free OldPortForHttp
```
For more information, see wcfhttpconfig (Team Foundation Build).
At the command prompt, run wcfhttpconfig reserve UserAccount URL. The command statement should resemble the following:
```
wcfhttpconfig reserve Domain\Account https://+Computer:NewPortForHttps/Build/v2.0/AgentService.asmx
```
Add the port to the exceptions list for Windows Firewall.

Installing the Certificate on Client Computers

Every client computer that accesses Team Foundation must have the certificate installed locally. Additionally, if the client computer has previously accessed a Team Foundation team project, you must clear the client cache for every user who uses the computer to connect to Team Foundation before that user will be able to connect to Team Foundation.

If your client computer is running Windows Vista or Windows Server 2008, you might experience errors when you attempt to install the certificate. You must install an update from the following page on the Microsoft Web site: How to use Certificate Services Web enrollment pages together with Windows Vista or Windows Server 2008. After you install the update, you must download the certificate manually from the certificate server and save it to the Trusted Root Authority store before you can complete the procedure below. For more information about how to save certificates, see the following page on the Microsoft Web site: Retrieve a certification authority certificate from a Windows Server 2003 CA.
