I'm experiencing the exact same problem as described here http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=593336. However I can't use root to login during an strace (seems to be a security issue) and logging in as user gives "Operation not permitted" error. Is there any other way I can diagnose the issue?

I'm using arch linux with pam_encfs 0.1.4.4 and util-linux-ng 2.18.

Hm, looks to be upstream issues.

Try applying attached file and checking your logs for information. (This patch is ancient, and might not apply 100% cleanly, should be ok though).

Thanks for the reply. The only errors that came up were these.

thats the exact parameters it'll use for the mount

encfs -v -o nonempty allow_root /home/nick/.crypt-raw /home/nick/crypt

try to see if you get any errors using that from commandline

If I run encfs -v -o nonempty allow_root /home/nick/.crypt-raw /home/nick/crypt I get an encfs error "When specifying daemon mode, you must use absolute paths (beginning with '/')". With encfs -v /home/nick/.crypt-raw /home/nick/crypt -o nonempty allow_root I get a fuse error "fuse: invalid argument `allow_root'". When I try encfs -v /home/nick/.crypt-raw /home/nick/crypt -o allow_root everything works. As a workaround I'll try just removing nonempty from my conf file.

Hmmm, that doesn't seem to have worked. Also the previous commands all work if you add a comma between the two fuse arguments.

http://code.google.com/p/pam-encfs/source/browse/trunk/pam_encfs.conf

It by default passes fuse arguments with , between them. You've removed the , from your configuration file.

Sorry didn't realise this was still when I posted a new issue.
