[ovirt-users] sign-out with kerberos sso

I have been setting up aaa, following the recipe in the RedHat portal: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Virtuali... and I can successfully authenticate, however the Sign Out button does not clear the session properly and does nothing. I found this long standing bug https://bugzilla.redhat.com/show_bug.cgi?id=884653 this bug was updated last month as supposedly fixed by an errata release of RHEV 3.5.0. I'm using FC20 with ovirt 3.5.1.1, Is there an equivalent fix in ovirt? If so how can I access it? Thanks, Alastair
