How do I change a MongoDB user's password?

I used db.addUser(...) to create a user at some point in the past. How do I now change that user's password?

I logged in with a user with userAdmin role. What command do I use to change another user's password?

Edit 2

I need this answered for the v2.4 style addUser and privilege documents

Edit

It has been suggested that I use the 2.2 addUser syntax to change the password. This does not work:

db.addUser({user: "test", pwd: "oldPassword", roles: ["readWrite"]})
db.addUser("test", "newPassword")

gives

uncaught exception: couldn't add user: system.users entry must not have both 'roles' and 'readOnly' fields

this might help.

Becareful about the argument passed. That is for readOnly option.

EDIT : Steps I followed in : Added a new user

> db.addUser("admin","firstpwd") 
{
    "user" : "admin",
    "readOnly" : false,
    "pwd" : "40a84fcba954c8924d277f23b0f880b1",
    "_id" : ObjectId("51966ec8c7ad876ba0319438")
}

exit

> db.auth("admin","firstpwd")
1

Changing the password 

> db.addUser("admin","secondpwd")
{
    "_id" : ObjectId("51966ec8c7ad876ba0319438"),
    "user" : "admin",
    "readOnly" : false,
    "pwd" : "82f4e416844349418281a3eca1cf6082"
}

exit

db.auth("admin","secondpwd") 1

MongoDB shell version: 2.4.3

To change a password, just run the addUser command again.

db.addUser("coolguy",  "newxH@x0rPasswd", true);
