My password on a Linux server was recently reset by the authorities that be, and the secure thing to do is naturally to immediately change your password upon logging in, to enhance privacy and security of the account. So much to my surprise did I encounter this response from the system:

-bash-2.05b$ passwd
Changing password for user waldo.
Changing password for waldo
(current) UNIX password:
You must wait longer to change your password
passwd: Authentication token manipulation error

So much for this company and their security policies. It sucks!
