[ovirt-users] kerberos and AAA

Hi, I've installed the LDAP AAA module for oVirt on the engine host, but I suspect I also need to bind the host to the domain first as I am getting 'peer not authenticated' when I try the auth. Is it ok to install sssd and the kerberos tools without on the engine host manually? I know that in general you should avoid installing things manually so wanted to check first. Thanks, Cam
