xa9ow (xa9ow) asked a question.
Kemp supports SAML, and is currently my best option for trying to get SSO/MFA on internal IIS sites. I can find some stuff about Okta and F5 but can't find any mention of anyone getting Okta to work with Kemp. Does anyone have any experience with this and can share their experience?

hi Jason,
That is a very good question.
While we do not have an official integration, we do have support for custom SAML integrations, and you may try to build one for this
This documentation can help you with the settings on the Kemp site:
https://support.kemptechnologies.com/hc/en-us/articles/212736383-SAML#MadCap_TOC_23_2
It is possible to do this, we've tested and have successfully made the Kemp act as the sP (Service Provider) with OKTA acting as the IdP (Identity Provider) in the SAML authentication exchange. We did this to allow us to activate 2 factor authentication (2FA) on web applications where this is not natively supported.
We successfully got it to work with a couple of internal Microsoft IIS based websites and Microsoft Exchange 2016 (OWA).
Very briefly: We found that using KCD (Kerberos Constrained Delegation) was the key, essentially the Kemp Load Master captures the incoming connection to the website, redirects to OKTA for authentication (IdP) you can add 2FA here if you need it.
Upon successful authentication redirects back to the Kemp. At this point the Kemp uses KCD to get a Kerberos impersonation ticket from the KDC (Active Directory Domain Controller in this case), which it then presents to the Real Server back end when making the connection (impersonating you the user authenticated via SAML), assuming your Real Server is configured to accept the Kerberos authentication you should find all just works as if you went direct to the Real Server from your client machine (assuming it has a Kerberos ticket). I believe there are a few caveats to this, i.e. some applications don't support it, but if your application has a simple logon approach hopefully this will work for you.
I've written this up as I couldn't find any detailed explanation, hopefully its of some use to assist and/or point you in the right direction.
