pam_ecryptfs doesn't insert wrapped passphrase into keyring

[Florent B]

Hi,

I'm using Ubuntu 18.04, with eCryptFS 111-0ubuntu5.

I'm trying to use eCryptFS on a custom directory (not home, not Private directory).

The first step of using eCryptFS to unwrap passphrase and insert it to keyring is causing me troubles with pam_ecryptfs.

My wrapped passphrase is in ~/.ecryptfs/wrapped-passphrase

I can successfully use "ecryptfs-insert-wrapped-passphrase-into-keyring" using my login password to unwrap. My passphrase is inserted in keyring.

But if I let pam_ecryptfs do it, it does not work : key is not present in keyring.

pam_ecryptfs seems configured :

$ grep -Hr pam_ecryptfs /etc/pam.d/
/etc/pam.d/common-session:session optional pam_ecryptfs.so unwrap
/etc/pam.d/common-auth:auth optional pam_ecryptfs.so unwrap
/etc/pam.d/common-session-noninteractive:session optional pam_ecryptfs.so unwrap
/etc/pam.d/common-password:password optional pam_ecryptfs.so

It seems to detect my wrapped passphrase on login :

$ cat /var/log/syslog | grep pam_ecryptfs
Jun 27 19:37:18 FlorentTux gdm-password]: pam_ecryptfs: Passphrase file wrapped

But it is not inserted in keyring (checked with "keyctl list @u").

What more can I do to debug my issue ? I probably did something wrong, but I don't know what.

Thank you.
Florent
