Error in Password module

No. I'd say:

[filippo@nethservice ~]$ rpm -qf /tmp/
filesystem-2.4.30-3.el6.x86_64
[filippo@nethservice ~]$ rpm -V filesystem
[filippo@nethservice ~]$ stat /tmp/
  File: `/tmp/'
  Size: 552960    	Blocks: 1088       IO Block: 4096   directory

$ ls -ld /tmp/
drwxrwxrwt. 19 root root 552960 Jan 12 23:28 /tmp/

Then, my commands would be:

chmod 1777 /tmp
chown root:root /tmp
