Kerberos Constrained Delegation
Contents
1 Introduction
As part of Kemp's Edge Security Pack (ESP), the LoadMaster supports a number of authentication protocols, including Kerberos Constrained Delegation (KCD). When using KCD as the server authentication protocol, the LoadMaster provides seamless access to protected resources in a Kerberos realm, even when credentials provided are not directly valid for such an environment.
The KCD authentication protocol is used to confirm the identity of the users who are attempting to access resources on a network. KCD authentication uses tickets that are encrypted and decrypted by secret keys and do not contain user passwords. These tickets are requested and delivered in Kerberos messages. When the user's password is not provided, a trusted administrator user account is used to get tickets on behalf of services and users.
1.1 Document Purpose
This document provides instructions on how to configure Kerberos in the LoadMaster.
1.2 Intended Audience
This document is intended to be read by anyone who is interested in finding out how to configure the LoadMaster to authenticate using KCD.
2 Configuring KCD and the LoadMaster
Refer to the sections below for instructions on how to configure KCD and the LoadMaster.

2.2 Ensure All Relevant Stations Use the Same Domain Name System (DNS) Server
Verify that the Virtual Service and the Real Servers have Pointer (PTR) records by running a ping command, for example ping -a 192.168.2.200.
2.3 Check if the LoadMaster is Configured to Reverse Resolve IP Addresses
From the SSOMGR in debug mode, you should see similar logs:
Aug 4 15:56:54 vwagwosevlb00 ssomgr: #18806# >>> kcd_get_user_ticket
Aug 4 15:56:54 vwagwosevlb00 ssomgr: #18806# >>>resolve_destination_address: Attempt to resolve destination [10.179.194.80][2]
Aug 4 15:56:54 vwagwosevlb00 ssomgr: #18806# <<<resolve_destination_address: Resolved destination host name [wosevtspf3.wof.az.xyz]
This provides a quick indication that the LoadMaster is correctly configured to reverse resolve IP addresses.
2.4 Ping Simple Host Names
Ensure that it works with just the name, not the Fully Qualified Domain Name (FQDN).
When adding Real Servers to the Delegation tab of the trusted user (in a later step), Windows automatically adds both simple host names and FQDNs.
To test if the host name works, ping it by following the steps below:
1. In the main menu of the LoadMaster Web User Interface (WUI), expand System Configuration > Logging Options and click System Log Files.
2. Click Debug Options.
3. Type the host name in the Ping Host text box and click Ping.
If the result is unknown host, you must provide the domain realm to append to the hostname as a Search Domain. Refer to the Specify a Search Domain section for steps on how to do this.
2.5 Specify a Search Domain
If you got an unknown host error when pinging the host name in the Ping Simple Host Names section, you must provide the domain realm to append to the hostname as a Search Domain. To do this, follow the steps below:
1. In the main menu of the LoadMaster WUI, expand System Configuration > Network Setup and click Host & DNS Configuration.
2. Type the domain realm in the Domain field and click Add.
3. Run a ping again (follow the steps in the Ping Simple Host Names section). Now that the search domain is added, the ping should be successful.
4. Run a ping on each of the relevant Real Servers to ensure they correctly resolve.
2.6 Ensure Time/Date/Time Zone Settings Are Correct
Ensure that all devices are on the same time, date and time zone settings. The LoadMaster settings are available in System Configuration > System Administration > Date/Time.
2.7 Create the Trusted User
Follow the steps below to create the trusted user in the Active Directory settings.
1. Log in to your Domain Controller.
2. Launch Active Directory Users and Computers and select Advanced Features from the View menu.
3. Click View and click Advanced Features.
4. Create a new user as shown below.
5. Set the password to never expire.
6. Select the Attribute Editor tab.
7. Navigate to servicePrincipalName.
8. Select servicePrincipalName and click Edit.
9. Type http/trusteduser in the Value to add field and click Add.
10. Click Apply and OK. The window must close before you open it again (to see the new Delegation tab).
11. Open the user properties window again and the Delegation tab becomes available.
12. Select the Delegation tab.
13. Select Trust this user for delegation to specified services only.
14. Select Use any authentication protocol.
15. Add the Real Servers and add http as the service.
For SharePoint Apps: You might have to add the namespace published by SharePoint to enable KCD, instead of the actual server FQDNs.
16. Click Advanced.
17. Find the servers by name.
18. Select the Expanded check box.
19. You can see all servers with both the host name and the FQDN.
If you have a SharePoint environment that uses distributed name spaces, you must register these name spaces instead of the actual servers hosting the content.
20. For SharePoint, the settings may need to be configured as outlined in the above screenshot.
2.8 Create the Outbound Single Sign On (SSO) Domain
To create the outbound SSO domain, follow the steps below in the LoadMaster WUI:
1. Expand Virtual Services > Manage SSO.
2. Type a name in the Add new Server Side Configuration text box and click Add.
3. Type the Kerberos Realm and click Set Kerberos realm.
4. Type the Kerberos Key Distribution Center and click Set Kerberos KDC.
5. Type the Kerberos Trusted User Name and click Set KCD trusted user name.
6. Type the Kerberos Trusted User Password and click Set KCD trusted user password.
3 KCD Compatibility with Other LoadMaster Features
There are some compatibility issues with KCD and other LoadMaster features. For further information, refer to the sections below.
3.1 KCD Compatibility with the Web Application Firewall
As of the 7.2.40 LoadMaster firmware version, you cannot enable both WAF and KCD at the same Virtual Service level. For example:
If WAF is enabled in the parent Virtual Service, you cannot enable KCD as the Server Authentication Mode in the parent Virtual Service
If KCD is enabled in the parent Virtual Service, you cannot enable WAF
However, you can enable ESP/KCD in the SubVS and then enable WAF in the parent Virtual Service.
If you had WAF and KCD enabled at the same level before upgrading to 7.2.40 and you upgrade the firmware to 7.2.40 or above, the configuration will not be changed. File attachments in SharePoint will not work. To resolve this, enable WAF on the parent Virtual Service and ESP/KCD on the SubVS.
The following combination is not supported: WAF with ESP Client Certificate authentication and KCD.
3.2 KCD Compatibility with Response Body Modification Rules
Response body rules are not compatible with KCD. If KCD is enabled on a Virtual Service, it is not possible to assign a body rule to it.
