Details about issue

I mounted my s3bucket as via /etc/fstab.
What's working:
Writing files to bucket as any user on EC2 instance.
Reading files from bucket, that the EC2 user created himself.
Reading ALL files (and folders) as su of EC2 instance.

What's not working:
Reading files as normal user of EC2 instance, that he didn't create / were created via the S3 webinterface / console.

ls -al /mnt/s3bucket
-rw-rw-r-- 1 root root 259216 Jan 11 13:57 3.png
-rw-rw-r-- 1 root root 12 Jan 11 13:57 hello.txt
d--------- 1 root root 0 Jan 11 14:21 newtest
drwxrwxr-x 1 root root 0 Jan 9 10:36 test1
drwxrwxr-x 1 ftpuser ftpuser 0 Jan 11 13:59 test2
-rw-rw-r-- 1 ec2-user ec2-user 6 Jan 11 14:30 test2.txt

The files 3.png and hello.txt as well as the folder newest were created via the s3 webinterface. The rest is created directly via ssh. If I want wo read any of those 3 files I get this message:
tail /mnt/s3bucket/3.png
tail: cannot open '/mnt/s3bucket/3.png' for reading: Permission denied

As su thats not a problem. How can I fix it, so that every/another user of my EC2 instance can read those files?

Thanks a lot.

@Timboo89
I think that similar problems have not occurred at s3fs so far.
So 3.png file is allowed read access for other users but you can not read it, we should know permission for mount point directory.
Other than that, you can try to use uid/gid/umask/mp_umask option for s3fs.

Thanks in advance for your assistance.

Thanks a lot =)
This is working well!
For everyone who does not know how to get the uid of a user, hit the following in your shell:
id -u username
The /etc/fstab entry looks like this:
s3fs#mybucket /mnt/s3bucket fuse _netdev,rw,nosuid,nodev,allow_other,uid=XX 0 0

In case someone on Mac having this issue, I managed to be able to read folders and files with the below command:

s3fs BUCKET_NAME /path/to/mount/ -o passwd_file=/path/to/credentials,allow_other,uid=`id -u`,umask=0077,mp_umask=0077,use_cache=/path/to/cache/ -d -d -f
