No "ghost" entries at all. Everything is perfect. Yeah, this was crazy
that it was the fix on all the problems I had for a few months. It
definitely was not an obvious one. I had wondered if it was DNS at one
point, but every server/master has a /etc/hosts file with all hostnames
and IPs (I never trust DNS).

Do not disable IPv6 stack on your machines. By disabling IPv6 you are
not doing good. On contrary, many contemporary software projects are
using IPv6-enabled network calls by default because both IPv6 and IPv4
share the same name space on the machine so you only need to listen on a
IPv6 port to accept both IPv4 and IPv6. This is a recommended approach
for networking applications' developers for years already.
Note that this means only that support for IPv6 stack is enabled in the
kernel. You are not required to go with IPv6 networking addresses, this
is not really needed if you don't want to. But allowing applications to
be IPv6 aware is required.
FreeIPA has several components which are programmed in such way that
they expect IPv6 stack to be enabled for reasons outlined above. If you
disable IPv6 stack, FreeIPA will partially malfunction and will not
really be in a supported state, especially when we are talking about
trusts to Active Directory (and, in future, IPA to IPA trust).
BTW - I did re-enable IPv6 and was able to "clean ruv" all the "dead" entries,
which I had not been able to do before. Thank you for this.
Thanks for confirmation! I added this knowledge to
as it is definitely not an obvious fix to resolve the RUV issue.
Please feel very welcome to extend Troubleshooting guide if you have other
advise that could help others speed up their RUV investigation - you have
definitely a lot of experience with them.
Thank you for sticking with all my issues and helping with this. This
one was a huge help. At one point I had 9 of these ghost RUVs that
would not go away. Even if I deleted them off a server, they would
magically re-appear. It was so frustrating. Having a clean environment
is a wonderful thing. I love IPA!!
I will check the DOCs and if there is anything I can add I will.
