pam_shells -- PAM module to check for valid login shell
     __________________________________________________________________

DESCRIPTION

   pam_shells is a PAM module that only allows access to the system if the
   user's shell is listed in /etc/shells.

   If this file does not exist, entries are taken from files
   %vendordir%/shells, %vendordir%/shells.d/* and /etc/shells.d/* in that
   order.

   It also checks if needed files (e.g. /etc/shells) are plain files and
   not world writable.

OPTIONS

   This module does not recognise any options.

EXAMPLES

auth  required  pam_shells.so
