> Ahh, this is the issue. Above configuration is valid for oVirt 3.x, but in 4.0 we have quite new OAuth base SSO, so you need to use following configuration:

> <LocationMatch ^/ovirt-engine/sso/(interactive-login-negotiate|oauth/token-http-auth)|^/ovirt-engine/api>
>   <If "req('Authorization') !~ /^(Bearer|Basic)/i">
>     RewriteEngine on
>     RewriteCond %{LA-U:REMOTE_USER} ^(.*)$
>     RewriteRule ^(.*)$ - [L,NS,P,E=REMOTE_USER:%1]
>     RequestHeader set X-Remote-User %{REMOTE_USER}s
>     AuthType Kerberos
>     AuthName "Kerberos Login"
>     Krb5Keytab /etc/httpd/s-oVirt-Krb.keytab
>     KrbAuthRealms AD.HOLDING.COM
>     KrbMethodK5Passwd off

> Also as 4.0 is working on EL7 you may use mod_auth_gssapi/mod_session instead of quite old mod_auth_krb. For mod_auth_gssapi/mod_sessions you need to do following:
>
>   1. yum install mod_session mod_auth_gssapi
>   2. Use following Apache configuration
