Trying to manage OES2SP2 NSS quotas with ConsoleOne,

from the properties of NSS volume, we have Users with Space Restrictions...
for some volumes it shows the correct information, with userslist and
restrictions, for some volumes (even on same server) it simply shows

When using other tools, like dspace.exe, it shows quotas correctly for
all drives (so NSS attributes are ok, quotas are applied and working).

Anything to check to get C1 working correctly?
