Using Netscaler as ADFS proxy - Exported configuration

After my last blog article on how to replace the Microsoft ADFS Proxy, I've been asked to provide the configuration of my Netscaler for the ADFS proxy replacement so I've exported the part that are needed to achieve this, please comment with a little thanks if it was helpful to you. Note that I'm using Netscaler 10.1 with ADFS 2.0 on windows 2008r2.

I found a Citrix article about ADFS 3.0 that refer to the fact that Netscaler doesn't support the sni feature for the backend server that is used in ADFS 3.0 which is most likely causing headache to ADFS 3.0 users.

The citrix article refer you to this microsoft article that talk about a way to partially disable the SNI feature for ADFS 3.0...

Here's the code and some comments :

********* Begin Starting Notes *******
This config is for Netscaler 10.1 (Currently at Build 129.11 but it's been working with previous 10.1. build)
Your Netscaler must be licensed for "AAA - Traffic management" and it must be enable under settings -> "Configure Basic Features" (Authentication, Authorization and Auditing)
Your ADFS URL must be reachable by DNS externally (you can't authenticate using IP address, it has to be a DNS name, worst case scenario you can edit your host file temporarily for testing)
you need to have an external IP address available to Setup the Reverse Proxy

If you have multiple domain, you can easily repeat the config for the second domain and add the 2nd LDAP policy to the authentication Vserver with a different priority

Example: bind authentication Vserver vs_Auth.Company.com -policy Subdomain2.Company.com -priority 110
The domain settings in the Netscaler is not related to the AD domain but to the domain in the FQDN url (i.e.: email domain, If your internal domain is company.local and your website is company.com then the domain you set in the Netscaler is company.com)

For LDAP authentication action, you have to create a standard user (no special right required except "password never expire") for the netscaler to use this account to log in to the LDAP server and check for the user credential. The GUI offer an option to test the LDAP credential to make sure the connection works.

The Domain you set on your ADFS_Proxy_replacement and on your Auth.company.com MUST MATCH with the domain in the URL your users are sent for the ADFS authentication. My ADFS is setup as fs.company.com, this is the name clients will connect to, and so it must be resolvable via DNS externally.

Fs.company.com must resolve to your LB_ADFS_Proxy_Replacement_FullAuth_Forest
