[ovirt-users] Unable to login to the WEB UI

Wed Aug 10 18:50:02 EDT 2016

I'm not sure it's a good idea if you're running 4.0. This procedure does half of the job as it don't touch the custom java trust store and missing parts are mandatory for ovirt 4. So I'm now stuck with an unreachable UI after
an upgrade and I don't know if I can roll back.

If you are using CAS (althought it's officially supported by oVirt), that probably means you have configured cas authentication on Apache, passing authenticated username using aaa-misc as authn extension and aaa-ldap as authz extension (to get group memberships for authenticated user). If that's true then please take a look at
