Automount share as non ROOT or SYSTEM user!

The most annoying bug I've found yet!


I have two machines, an iMac and a Mac Book Pro.


The MBP was an upgrade from 10.6.8 to 10.7 the iMac was a full reinstall (erased the drive and booted off a flash installer I made for 10.7)


The MBP was previously configured (in 10.6x) to automount a few AFP shares from my local NAS. This had been working perfectly. After upgrading to lion, the entries in /etc/fstab were still there and the shares are still functioning fine.


I added the EXACT entries from the fstab file on the MBP to the fstab on the iMac. Now when the iMac boots the AFP shares are automounted by the system/root user and therefore are not accessible to any normal (admin) user on the iMac. No matter what I try I can't get it to automount those shares as a non system/root user. Clearly something changed with AFP configuration in Lion, yet the upgraded MBP still funcitons as it did before, so some new default automount / autofs setting has changed yet it wasn't touched in the upgrade. I'm wondering if anyone is aware of an AFP or Automount or autoFS setting I can try changing on the iMac to get this working?


To test things further, I changed the FSTYPE in fstab from afp to cifs just to test and it still mounts the shares as the root/system user. Yet if I use mount_afp or mount_smbfs it will obviously mount those shares as the user that is running the command, which is desirable. The only problem in doing this is if I disconnect from the network or the share drops it will not automatically reconnect and I'd have to run the command again.

iMac, Mac OS X (10.7), Extreme 2.8ghz 16GB RAM

Thanks for the tips, I've tried all of these before, and just tried it again, still, they end up mounted as root.


The mountpoint's folder perms show as (no matter what I do before or after mounting):


dr-xr-xr-x 2 root wheel 1 Dec 2 21:51 files-3



When I simply type "mount", that mount shows as:


map auto_afp on /Volumes/NAS/files-3 (autofs, nosuid, automounted, nobrowse)



Where other shares that I mount using "mount_afp" will add to this to the end of the ( ) area: "mounted by user"


I've tried changing the mount point to my a folder inside my home folder, it's stll mounted as root and chowned to root. I've tried chowning the auto_afp and auto_master to user:wheel, nothing seems to change it.


I'm bummed, becuase CLEARLY something changed in Lion, this ALL worked PERFECTLY and it was awesome to have on demand mounts (specially for the laptop when I would leave the NAS at home and come back)


Unfortunatley I've had to resort to a stupid script that I will run that runs mount_afp commands which properly mounts the share as my user, I've also added some options to make it more "sticky" (ie it takes longer to time out) but again, it's FAR from perfect like autofs was.

Okay I just had to reboot my MacMini system because of trying to get something else fixed and found that my mount point didn't come back up with user permissions (root only). So I did the following.


  1. Removed entry from /etc/auto_afp
  2. Restarted autofs (automount -vc)
  3. Removed the mount point in /Volumes
  4. Readded entry to /etc/auto_afp
  5. Restart autofs
  6. Checked Share and had access


My mount point is /Volumes/Media and when I removed if from autofs and restarted autofs the mount point was left behind with incorrect permissions. I removed it and DID NOT recreate it before restarting autofs again. This seemed to have fixed the permissions issues. However, this did not survive a test reboot of the system, so it looks like maybe when autofs is shutting down it doesn't remove the mount point?


Don't know.

I've been having this problem as well on Lion. Snow Leo worked fine, exact same configuration. Even if I remove the mountpoints, they get re-created properly, however, they are mounted with root permissions. It's really bizzare. I expect Apple did something in the name of security, that broke the only use case I can see for the autofs daemon......


I wonder if we can replace it with a compiled from source version from BSD or something.....

Damnit Apple. NFS works till you try to use it, then you get disconnect errors. The only conclusion I have at this point is that autofs is totally broken in Lion and is useless. On the box I really need this functionality I'll probably have to revert to snow leopard as it worked perfectly there and the changes is Lion don't matter to me on that machine. Drives mounted directly via cmd-K work fine, so it has to be autofs, not the network/sharing stack or the server side.


Hacks like using login items are not sufficient for everyone. The biggest problem is that they don't auto-reconnect if the server reboots or the network disconnects etc.. IMO this is a really basic function of any Unix based OS these days and having it so broken is a huge failure in QA. If they don't want to support the normal autofs daemon, then they should completely remove it and move the functionality to the GUI. In this day and age of pervasive home networks, there is no excuse for not having the equivalant of the stupid automount checkbox that Windows has had since Win95. Ideally, they would fix autofs and provide a simple UI for it like that checkbox in Windows when mounting a drive.

Apologies if someone already said this.


I was having this problem too. Here are the bad permissions on the mountpoint:


[bwood@ucbmbp ~]$ sudo ls -ld /Users/bwood/share

dr-xr-xr-x 2 root wheel 1 Dec 21 23:38 /Users/bwood/share


I resolved the root ownership of mountpoint on 10.7 like this:


1. as normal user create the mountpoint directory: mkdir ~/Linkstation

2. make the needed edits to /etc/auto_master and (in my case) /etc/auto_smb. My auto_smb contains


/Users/bwood/Linkstation -fstype=smbfs ://admin:PASSWORD@192.168.0.160/share


3. sudo automount -vc


[bwood@ucbmbp ~]$ sudo ls -ld /Users/bwood/Linkstation/

drwx------ 1 bwood wheel 16384 Nov 27 20:46 /Users/bwood/Linkstation/



[bwood@ucbmbp ~]$ ls Linkstation/

I tried creating the directories for mount points as a normal user. The autofs daemon would change the permissions for me....


I got NFS working properly. Added "locallocks" to the mount options. Here's a sample line:


Travis -rw,rwsize=1048576,vers=3,noatime,intr,soft,locallocks 10.1.0.2:/raid/Travis


Now the mounts work properly and don't disconnect constantly. I never did get SMB reliably working.

Looks like mine with "noowner" are working:


in /etc/fstab I have


192.168.89.105:/music /Users/Deborah/Shares/music url automounted,noowners,url==cifs://(username):(password)@192.168.89.105/music 0 0


and /etc/automaster has

+auto_master # Use directory service
/net -hosts -nobrowse,hidefromfinder,nosuid
/home auto_home -nobrowse,hidefromfinder
/Network/Servers -fstab
/- -static


I had to remove the entries from fstab, issue a sudo automount -vc to remove the mounts, then manually create the mount point at /Users/Deborah/Shares/music using mkdir music, then sudo chown Deborah:staff /Users/Deborah/Shares/music, then put the entries back in fstab, and do another sudo automount -vc to mount them again.


It's too early to say for sure whether this will last any length of time.


In Snow Leopard I didn't have the noowners option, and it worked fine. Must have broken when upgrading to Lion. With noowners, everything in the share is owned by the current user, which is fine for me since I don't rely on the user permissions within my NAS.

This works for me. I think the key is setting the mount point in your home directory instead of /Volumes/


my configs looks like this


I added this line to the end of /etc/auto_master:


/- auto_smb




and created the file /etc/auto_smb:


/Users/er0k/mount -fstype=smbfs,soft ://er0k:password@server/mount



I had a problem with this as well. Apple must fix this! In the mean time, however, here is something that works on OSX 10.8.


Follow the procedure 'surroscape' suggested. However, on OSX 10.8 the shares will mount as root owner. To fix this run this:


sudo umount /mount/point


This will unmount that share. It should automatically remount with your user permissions automatically. I know, it's idiotic, but it works. Apple, FIX this!

Automount share as non ROOT or SYSTEM user!
