Greetings,

I have been searching far and wide and cannot seem to narrow this one down. I am running Debian Jessie with LXDE, but not booting to LXDE. I have a USB drive connected to my system and autofs configured and all Auto-mount features unchecked in LXDE/pcmanfm. So if I boot to command line and let autofs mount the USB drive, it mounts as root with permission of 777, just as I have specified in my auto.misc file. However, if I go into LXDE and let autofs mount the drive, it mounts as my user account and permissions of 700. To illustrate, I configured with 2 USB drives and let the first drive mount before loading LXDE and the second I mounted after going into LXDE:

drwxrwxrwx 13 root root 12288 Dec 31 1969 primary
drwx------ 2 grendelos grendelos 4096 Dec 31 1969 secondary

Here is what my auto.misc file has:

primary -fstype=vfat,rw,noatime,nodiratime,user,umask=0 :LABEL=LEXAR_BLUE
secondary -fstype=vfat,rw,noatime,nodiratime,user,umask=0 :LABEL=MC_4GB

So what I can't figure out is how LXDE ties into automount/autofs in order to prevent this from happening. Anyone have any idea?

vaguely guessing that the mechanisms that take care of these things on LXDE are still active in the background, even when you disabled the gui features.
gvfs, udisks, udisks2 are things i'd look at. maybe you don't need them at all if autofs takes care of mounting?

After looking into your suggestion further, I believe you are right. I can confirm the problem is limited to LXDE as I did a parallel installation with Xfce and did not experience this issue.
