Permission denied for user accessing mount

Permission denied for user accessing mount

Using root I can mount another Linux share no problem.
root@crunchbang:/mnt# mkdir javalib
root@crunchbang:/mnt# mount -t cifs //10.1.3.7/javalib ./javalib -o
username=guest
Root can read/write to the share dirs no problem.
root@crunchbang:/mnt# ll
drwxrwx--- 9 500 users 0 Apr 13 17:59 javalib
root@crunchbang:/mnt# cd javalib
root@crunchbang:/mnt/javalib#
When trying to access the dir under another user, even when the user is
part of the 'users' group it gets permission denied.
shawn@crunchbang:/mnt# cd javalib
bash: cd: javalib: Permission denied
Thank you,
