The next route I will try - is the one Youeen took, using ipa-adtrust

Hi Chris,
Okay this is good to hear.
But don't we want a IPA managed Scheme ?
When I did a "ipa-adtrust-install --add-sids" it also wanted a local
installed Samba and I wonder why.
Good that we make some progres on making it all clear.
Cheers,
Matt
