[SunHELP] LS command not working

[souleymane kante]

Hi
I have already post this problem on this list but the problem is not solved. So
I post it again.
I have a Sun Box with solaris 2.6.  I don't know what happen but since monday
any user can't see the files and the directories contents with the LS command.
All the files and directories have read permission for everyone but only root
can see the files and directories contents with the LS command.

#which ls
/usr/bin/ls
#ls -ld /
total 536
drwxr-xr-x  24 root     root        1024 Mar 27 17:28 .

when a user type #ls /  , nothing appear :
#ls /
#

Help
