You have to perform following steps:

Check whether the error is false positive (script failed to extract
variables) or true positive (variable list changed).

If it is false positive:
- Fix this script.
- The same fix is needed in shadow package in shadow-login_defs-check.sh.

If it is true positive:
- Check-out shadow package and call shadow-login_defs-check.sh.
- Compare its output shadow-login_defs-check-pam.lst with
  pam-login_defs-vars.lst in the pam build directory.
- Update shadow encryption_method_nis.patch, if needed.
- If encryption_method_nis.patch was updated, update
  login_defs-support-for-pam symbol version in both shadow and
  pam spec files accordingly.
- Update checksum in this script.
