1. Whether the password resides in /etc/passwd or /etc/shadow makes no
   difference in terms of validation. /etc/shadow is merely an extra
   precaution against people having access to crypted passwords.

2. The encrypted password you quote above does not look like the output
   of crypt (the traditional unix DES-based one-way funciton intended
   for passwords). Could it be that your system is configured to use a
   different, possibly stronger crypting function?

   Try looking in /etc/pam.d -- apparently you're using md5 encryption
   and not the traditional crypt.
