It doesn't appear your /etc/pam.d/other file is even authenticating using
the shadow password functions i.e:

auth       required     /lib/security/pam_pwdb.so shadow
account    required     /lib/security/pam_pwdb.so

also, most modules support the debug option, try using this and checking
for errors:
auth       required     /lib/security/pam_pwdb.so shadow debug
account    required     /lib/security/pam_pwdb.so debug

Lastly, pam_unix_auth.so, pam_unix_auth.so, pam_unix_passwd.so, and 
pam_unix_session.so are now one module: pam_unix.so .
