[ovirt-users] LDAP sources

Hello, I have tried googling and searching in the documentation, but i can't seem to find any instructions on how to remove a authentication source. The background is that i did set up an FreeIPA server for auth, worked perfectly, but i ran into some problems using that to auth other systems, so i had to setup a new FreeIPA server and added that to oVirt, but now i want to remove the old one, but can not seem to find how. Anyone sitting on that info? And while on the subject, how do i set the FreeIPA auth as default auth source in oVirt? Regards Magnus
