Seems that gnorpm-auth modules are mistakenly put in
while they should be in /etc/pam.d and /etc/security/console.apps
This makes gnorpm-auth nonworking. Moving them to standard place
solves the problem.
( /usr/etc/ subdirectory did not even exist before gnorpm installation.
It is obviously not a standard placement for configuration on RedHat 6)
