[Samba] SLES10 SP1 3.0.28 - Excel files set read-only after recent updates

[bdehn at oreillyauto.com]

After recent Samba updates to one of our SLES10 SP1 systems users who open 
Excel workbooks with multiple sheets linked in end up with the Read-only 
attribute set on the original file. I found references to this in the 
3.0.23 days but nothing recent. The applicable rpms on this system are :

yast2-samba-server-2.13.22-0.8
samba-client-32bit-3.0.28-0.4.3
samba-3.0.28-0.4.3
yast2-samba-client-2.13.36-0.8
samba-pdb-3.0.28-0.4.3
samba-32bit-3.0.28-0.4.3
samba-client-3.0.28-0.4.3
samba-winbind-32bit-3.0.28-0.4.3
samba-winbind-3.0.28-0.4.3

Everything has been working great until this. What can I do to correct 
this?
