ecryptfs encrypted home folders: Unable to login with ftp, samba

Hi all

I am using Ubuntu 12.04 with two user accounts and both are encrypted with ecyptfs utility. Either of the home folders have data around 300GB. Its working fine except I cannot login using ftp or samba from my phone to copy data. I wanted to remove the encryption but the data is too big to copy and more importantly I want to retain the encryption.

So my real question is can I make any changes in pam.d folder's config files to allow my passphrase to be unlocked by ftp login or samba login.

Thanks in advance.
