Greetings.
Over the years, a number of times, people have asked us about migrating
from our own custom Fedora Account System (FAS) to FreeIPA.
We would love to, but right now as things stand it's just not a great
fit for us. In the past we have had trouble articulating what the
issues are, but now Patrick has written up a wiki page with all the
items we know of:
https://fedoraproject.org/wiki/Infrastructure/fas_freeipa
Hopefully we can keep open a dialog with FreeIPA folks and keep the
above wiki page synced up so perhaps someday we can migrate when
blockers are no longer in our way. :)
