Can't install programs and unlock settings

OSX apparently needs to regenerate a fresh auth.db from /System/Library/Security/authorization.plist.
This can be triggered in terminal with the following command: sudo mv /var/db/auth.db /var/db/auth.db.old
After rebooting the system everything works as it should be.
but yes, if you know how to resolve the first problem, the op one.... that would be great
