Im belonging to the group adm but I can not access to the directory..It says: "Permission denied".

What is the entire path? if it's /home/apache2 you'll need 770 from /home on up. – NickW Jun 14 '13 at 15:30
it is /var/log/apache2 – user35538 Jun 14 '13 at 15:30
what are you trying to do to the directory? – NickW Jun 14 '13 at 15:32
I just want to print the apache log using "tail -f /var/log/apache2/error.log" – user35538 Jun 14 '13 at 15:32
There you are then, it's the permissions on error.log. Try doing sudo ls -all or su'ing up to root – NickW Jun 14 '13 at 15:41

After you are added to a group, you will need to log out, then in again, or do an su - <yourusername> to get the system to recognize your new privileges.
