Environment:

OS X 10.10.5 (Yosemite)

Summary:

The user module makes changes to users, such as changing the UID, in check mode.

Steps To Reproduce:

Assuming a user test1 already exists with a UID other than 3333:

dscl . -read /Users/test1 UniqueID
ansible localhost -m user -a 'user=test1 uid=3333' --check
dscl . -read /Users/test1 UniqueID

Expected Results:

No changes should be made.

Actual Results:

The UID of the user is changed:

sh-3.2# dscl . -read /Users/test1 UniqueID
UniqueID: 9999
sh-3.2# ansible localhost -m user -a 'user=test1 uid=3333' --check
localhost | SUCCESS => {
    "append": false,
    "changed": true,
    "comment": "",
    "group": 4294967295,
    "home": "/Users/test1",
    "move_home": false,
    "name": "test1",
    "shell": "/usr/bin/false",
    "state": "present",
    "uid": 3333
}
sh-3.2# dscl . -read /Users/test1 UniqueID
UniqueID: 3333

The user module will also set the password in check mode.

It also adds and removes groups, as well as changing users to be hidden/not hidden.
