Hello, Martin

Before I wrote: Kerberos authentication FOR WINDOWS WEB SERVERS working successfully from Internet Explorer & Forefox.
Kerberos authentication NOT working with oVirt Web-Portals.

I expect that the users opening the oVirt web portal in the browser did not enter a password, and used instead of the transparent sign-on using Kerberos.
It is impossible ??

It's possible and it's working fine when everything is properly set up. But please bear in mind kerberos SSO is one of the most complicated oVirt setup, but usually the error is on kerberos side (environment issues on the client).

So, you are saying that using curl you are able to access API using kerberos ticket but when you try to access the same API from the browser it does not work, right?

I don't use IE, but you need to set following options in "about:config" URL for Firefox to work properly with kerberos:

network.negotiate-auth.delegation-uris = .ad.holding.com
network.negotiate-auth.trusted-uris = .ad.holding.com

If you have those options set, what exactly happen when you try to access https://kom-ad01-ovirt1.ad.holding.com/ovirt-engine/api

in Firefox?

Hi Aleksey,

in your last email you wrote that everything works (at least that's my understanding, email pasted below). So what exactly doesn't work for you?

Regards

Martin Perina
