Hello all,

First and foremost, a big "thank you!" to the FreeIPA developers for a

Now, to the point!

We're trying to re-provision a previous replica using the standard
documentation via the Red Hat site:

https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Identity_Management_Guide/Setting_up_IPA_Replicas.html

However, we're running into errors during the import process.  The
errors are varied and fail at random steps; there was an issue with
NTP or HTTP or LDAP, etc.  This did not happen when we promoted a
separate node to become a replica.

We had previously removed the replica via `ipa-replica-manage del` and
ensured that no trace of it being a replica existed: removed DNS
records and verified that the host enrollment was not present.  I did
not use the "--force" and "--cleanup" options.

What version of 389 are you using?
rpm -q 389-ds-base

When I check RUV's against the host in question, there are several.  I
also queried the tombstones against the host and found two entries
which have valid hex time stamps;  coincidentally, out of the 9
tombstone entries, 2 have "nsds50ruv" time stamps.  I'll paste
sanitized output below:

As you can see, the "host-in-question" has many RUV's and of which two
appear to be "active" and two entries which I believe (pardon my
ignorance) possibly correlate with the "active" entries of the
"host-in-question".

Do these two tombstone entries need to be deleted with ldapdelete
before we can re-provision "host-in-question" and add it back as a
replica?

Thank you,
John DeSantis
