I think it is mounted appropriately, from fstab:
/dev/VolGroup00/LogVol00 /          ext3    defaults,user_xattr  1 1
Related configuration settings:
         map archive = no
         map hidden = no
         map read only = no
         map system = no
         store dos attributes = yes

FWIW, I tested also on a configuration that doesn't use ext3 extended 
attributes, with configuration thus:
;       map archive = no
         map hidden = yes
;       map read only = no
         map system = yes
;       store dos attributes = yes
This had the same result (permission denied).

Thanks. I'll have another gander.

I'm reluctant to do so as well.

After posting this last night, I filed a new bug report. Jeremy replied, 
suggesting I try reproducing with the latest (3.0.34) release. Not too 
big of a deal, that host isn't in production yet.

I hope it turns out to be my configuration. I'll see if I can't tweak 
that to get it working as well.

Thanks for the pointers. I'll post the solution when I find it. I may 
have you look at my configuration before all's said and done.
