samba rename bug - solution?

[Eric Shubert]

I'm using rsync and cygwin to migrate some files from WinXP to samba 
(3.0.28-1.el5_2.1) on Centos (5.2). Files that have the read-only 
attribute are failing the final rename with "permission denied".

Permissions are all ok, and I've verified with manual testing that when 
attempting to rename a read-only file on a samba share from the Windoze 
CLI, it fails with "permission denied", so the problem appears to be 
with samba.

I've googled quite a bit, and found an indication that this indeed was a 
problem with samba and "might be fixed in 3.0.14a. Should be fixed for 
sure in 3.0.20rc1". So I'm running 3.0.28 (the latest COS5 version) and 
it appears to not be fixed in that version.

3 questions:

1) Does anyone know which version this might have been fixed in, or if 
it's fixed yet at all?

2) Where might I find a compatible rpm of a newer version of samba?

3) Any idea why is RHEL/COS so far behind with samba releases?
