What is the final resolution here? Do we plan to ignore the attribute
conversion for these attributes as, fixing DS or are we fixing the framework?

Surprisingly, I did not see the filed failure any more in my
ipa-replica-install tests nor in the latest CI run, I wonder if anything
changed in our code or if the issue is intermittent. Anyway, I am willing to
close this ticket if this is no longer a problem.
