[Samba] smbmount and long file names question

[jason]

running samba 2.2.7a (emerged in gentoo) on the client..
server is running samba  version 2.0.X

from my client, I run
 mount -t smbfs -o workgroup=mygroup,ip=10.1.1.50,username=$USER,uid=$ID,gid=$ID2
//smbserver/$USER /home/$USER/

and everything works great.. I do an ls in that /home/$USER dir
and the filenames are fine.. EXCEPT for files that have a :
in them. For example
dat-fil-401:1.log  becomes dat-f~10.log

if I rename dat-fil-401:1.log to something without ":" in it.
the long filename works fine. Any ideas how to make long filenames with
":" in then not get truncated?

regards,
Jason
