[Samba] Can't Assign Rights to Samba Share via ADS

[Joel Johnston]

I have been through the ringer on this one and need some specific
guidance on diagnosing and "healing" my mistake.  I have successfully
assigned my server to the domain and can browse to the server and its
shares via explorer.  However, I can't create directories or save files
from windows on my samba shares.  I've checked the directory permissions
and they all have read/write/execute (for the time being.)   What would
cause me to have read-only permissions on these files?  I need a better
understanding of "whose" in control as it pertains to permissions on a
linux share.
 
I'm running Fedora Core 1 with all of the latest updates vi up2date.
