[Samba] things that break with unix extensions = yes, samba 4.1.5 and osx 10.9 clients?

[Sabuj Pattanayek]

I'm about to do some testing with a an OSX 10.9 client connected to sernet
samba 4.1.5 to see what things work and don't both from the finder and from
the terminal with unix extensions = yes and no. Does anyone know of any
show stopping issues that occur with unix extensions = yes and the latest
samba (or 3.6.x, or 4.0.x a) and the latest OSX (or latest update with 10.7
& 10.8)?

Thanks,
Sabuj
