Continuing my frustration with changing my password on this one Linux system, I tried to be clever. So I logged in as root, then used:

passwd accountname

to force set the password. So much to my surprise, when I tried that, and I saw this response:

A valid password should be a mix of upper and lower case letters,
digits, and other characters.  You can use an 8 character long
password with characters from at least 3 of these 4 classes, or
a 5 character long password containing characters from all the
classes.  An upper case letter that begins the password and a
digit that ends it do not count towards the number of character
classes used.

Alternatively, if noone else can see your terminal now, you can
pick this as your password: "suck&Saudi&war".

Enter new password: 
Weak password: based on a dictionary word and not a passphrase.

Try again.

Firstly, suggesting a password such as suck&Saudi&war is downright hilarious, and secondly, my password that it considered weak and based on a dictionary word was similar to: Dhw$H32donw

Have no idea why that is based on a dictionary word... It complies with all the rules above.... %#$%#$%
