group permission is given, even after file is not read
it is not allowing to create file in /shared directory
mini@vaibhav-desktop:~$ touch /shared/minifile
touch: cannot touch `/shared/minifile': Permission denied
although mini user is the part of group testgroup
root@vaibhav-desktop:/home/min*i# ls -ld /shared
drwxrwx--- 2 vaibhav testgroup 4096 2012-06-19 01:24 /shared
why it is not working??
