Background:
This situation is using Rational ClearCase in a situation with server on
Solaris 10
and clients on a mixture of Windows XP and Windows 7, with access to the
VOB (repository) enabled via Samba version: 3.4.9
Users are getting a consistent error with a specific ClearCase operation
(Add to Source Control), which we have traced to a Samba interaction.
The issue:
For the interaction described, I need to know is it
a) Working as Designed (would then like to understand why it is designed
that way)
b) defective
c) dependent on Samba config/compile options (would then want to know
which options control the behaviour)
The file:
-r--r----- 1 cc_admin cc_users 5 Aug 1 16:29
/data01/vobstore/vobs_test_special.vbs/c/cdft/1c/19/1045e69c222a4a92bc1d733ec7cb1d6a
The Samba connection made (log message):

user rivacl (uid=20213, gid=9007) (pid 14214)

----------------------------
The request succeeds when the file permissions are 444 but fails when they
are 440
The connection resolves to being in the same group as the file, so it
seems to me the world readable bit should be irrelevant.
FYI attaching the output of "testparm -v -s"
Thanks you for any help you can give.
