Fprintd on login does not unlocks keyring

[calkekecal]

I have succesfully installed and using fprintd, however on login to debian it does not automatically enter though it accepts the fingerprint. Upon manually clicking, in the very beginning a box appears and asks for password to unlock the keyring. Is this a problem with libpam fprint or there is no way to unlock keyring and login to Debian with fingerprint?
