To be clear, we have not tested this combination so you'll be in uncharted
waters.

Since TGT for these users would still be issued by FreeIPA KDC, it would
include MS-PAC with SIDs of these users in FreeIPA domain -- once you
have run ipa-adtrust-install, of course. Thus, smbd on IPA master would
be able to recognize them as FreeIPA users regardless where they come
from -- IPA or Windows machines, as long as Kerberos is in use.

Any reports of how such setup would actually behave are welcomed.

The only requirements for simplistic setup is to:
1. run file server on IPA master (you can make a dedicated replica for that)
2. run ipa-adtrust-install on that master to setup Samba configuration
    and enable KDC + directory server to handle SIDs
3. use 'net conf setparm ...' to setup shares, since Samba on IPA master
    uses registry backend to store smb.conf configuration.

See
http://www.freeipa.org/page/Howto/IPAv3_AD_trust_setup#Using_Samba_shares
for sample how to work with 'net conf setparm'.

For 'valid users' I guess you can use simply user names since these
would be our local ones.

Again, this is completely untested right now.
