cups: installing wrong pam

[Romanenko Andrew]

The CUPS 1.4.2 can't authorize users via Web interface (AuthType: Basic).
To fix it, change /usr/local/etc/pam.d/cups
--------------------------------------------------
auth           sufficient      pam_unix.so
auth           required       pam_deny.so
account      required       pam_permit.so
password    requred        pam_deny.so
session        required       pam_permit.so
