Not sure if this is the right group - but looked closest out of them!
Starting to look at FreeIPA - so on
https://www.freeipa.org/page/Main_Page
I looked to join the mailing list "Freeipa-interest" but the link goes here -
https://lists.fedoraproject.org/archives/list/freeipa-interest@redhat.com/ - 404
All the others goto @lists.fedorahosted.org/ instead and
https://lists.fedoraproject.org/archives/list/freeipa-interest@lists.fedo...
does work - but is v empty :)
