Hi Ben, I's been 4 hours and nobody has replied yet so I'll bite.
IMHO, most (many) Samba issues can be resolved by correcting your
Linux pernissions and groups for your users.

What is the location of this test directories?
If both of these folders are trying to be changed by the same user
account why are both of these directories owned by different users?
I'm assuming that Mac1localuser and Mac2localuser both belong to the
staff group on the Samba server?

On this share you have:
writable = no
read only = no
These options are in conflict, you only need to specify one of these options.
man smb.conf shows:
# writeable (S)
#
# Inverted synonym for read only.
#
# Default: writeable = no
Hope that gives you some starting points.

<erno> hm. I've lost a machine.. literally _lost_. it responds to
ping, it works completely, I just can't figure out where in my
apartment it is.
