Possible long filenames problem with smbtar

Hi
	I am using Samba 2.0.6 on a SUN SPARC Solaris 2.6 machine. I compiled 
Samba using SUN cc with CFLAGS of "-fast". All the remaining configure 
parameters were left unspecified.
	
	I have been trying to use Samba to backup a nerwork of PCs onto the UNIX 
box. Each PC has a shared network drive, and the user issues an smbtar or 
smbclient backup command. eg.
	
% smbclient //dcmbpc/C "" -N -d 0 -U backup -D "/" -TcXqa test.tar "" 
"Entertainment" "My Documents/My Music" "Export/Game Demo
s" "Export/Unreal Tournament" "Windows/Win386.swp" "Win98"

	The backup itself seems to run without a problem. When I come to restore 
or list the tar file however, the long filenames get truncated. I have tried to 
list the tar with the SUN tar command and also restore it with smbtar and 
smbclient with no success. The output from a restore with smbclient is as 
follows:
	
....
restore tar file \My Documents\Office Documents\Application Framework - 
Tracee\Design Flow Diagrams\Backup\v0.04\Wo of size 29683 bytes
restore tar file \My Documents\Office Documents\Application Framework - 
Tracee\Design Flow Diagrams\Backup\v0.04\Wo of size 57389 bytes
restore tar file \My Documents\Office Documents\Application Framework - 
Tracee\Design Flow Diagrams\Backup\v0.04\Wo of size 53524 bytes
restore directory \My Documents\Office Documents\Application Framework - 
Tracee\Design Flow Diagrams\Backup\v0.04\rc
restore directory \My Documents\Office Documents\Application Framework - 
Tracee\Design Flow Diagrams\New Folder\
restore directory \My Documents\Office Documents\Application Framework - 
Tracee\Design Flow Diagrams\New Folder\RCS\
abandoning restore
Abandoning restore

	As you can see the filenames are truncatedto just "Wo". Also the restore 
aborts itself. The tar listing is as follows:
	
-rw-r--r--   0/0    65812 Jul 13 10:29 1999 ./My Documents/Office 
Documents/Application Framework - Tracee/Design Flow Diagrams/New Folder/Work

----------   0/0      121 Jan  1 01:00 1970 ././@LongLink

	The manual for smbtar states a limit of 1024 bytes for the filename and 
pathname. The filenames above do not exceed this limit, the number of bytes 
chopped off is only about 10-15 more.
	
	I would appreciate any suggestions as to why this might be happening.
	
		Cheers
