--- Comment #2 from Micah Veilleux <micah.veilleux@iba-group.com> ---
Thanks Shyam, you're right.  The results with the "cifsacl" mount option are
still problematic.  My mount options are now:
------------------------------
mcrw1:/TCS # grep "TCS " /etc/fstab
//mcrs3/TCS /TCS cifs
user=cifsuser,multiuser,domain=VPTC3,sec=krb5,iocharset=utf8,cifsacl,mfsymlinks,nobrl,vers=3.0
0 0
mcrw1:/TCS #
------------------------------

The "+" is still missing from the output of "ls -l":
------------------------------
mcrw1:/TCS # smbcacls //mcrs3/TCS /testfile -k yes
REVISION:1
CONTROL:SR|DP
OWNER:VPTC3\cifsuser
GROUP:VPTC3\Domain Users
ACL:VPTC3\Domain Admins:ALLOWED/0x0/RWDPO
ACL:VPTC3\cifsuser:ALLOWED/0x0/RWDPO
mcrw1:/TCS #
mcrw1:/TCS # ls -l testfile
-rw------- 1 VPTC3\cifsuser VPTC3\domain users 0 Sep 15 16:49 testfile   #
permissions are ok, owner and primary group owner are ok, but no "+" is present
to indicate the use of extended ACLs
mcrw1:/TCS #
------------------------------

"chown" fails with error:
------------------------------
mcrw1:/TCS # chown vptc3\\mveil testfile 
chown: changing ownership of 'testfile': Input/output error
mcrw1:/TCS # smbcacls //mcrs3/TCS /testfile -k yes 
REVISION:1
CONTROL:SR|DP
OWNER:VPTC3\cifsuser       # no ownership change made, but at least an error
was reported
GROUP:VPTC3\Domain Users
ACL:VPTC3\Domain Admins:ALLOWED/0x0/RWDPO
ACL:VPTC3\cifsuser:ALLOWED/0x0/RWDPO
mcrw1:/TCS #
------------------------------

"chmod" makes correct changes to the target user, but also incorrect changes to
other users:
------------------------------
mcrw1:/TCS # chmod u+x testfile
mcrw1:/TCS # smbcacls //mcrs3/TCS /testfile -k yes
REVISION:1
CONTROL:SR|DP
OWNER:VPTC3\cifsuser
GROUP:VPTC3\Domain Users
ACL:VPTC3\cifsuser:ALLOWED/0x0/FULL             # permissions changed as
expected
ACL:VPTC3\Domain Users:ALLOWED/0x0/0x00120088   # permissions set
unintentionally for "Domain Users", and removed unintentionally for "Domain
Admins"
ACL:Everyone:ALLOWED/0x0/0x00120088             # permissions set
unintentionally
mcrw1:/TCS #
------------------------------

"ls -l" now reports updated information, which is correct within the limits of
what it can convey, though the "+" is of course still missing:
------------------------------
mcrw1:/TCS # ls -l testfile
-rwx------ 1 VPTC3\cifsuser VPTC3\domain users 0 Sep 15 16:49 testfile
mcrw1:/TCS #
------------------------------
