|
|
description:
|
|
- Manage user accounts and user attributes on a BIG-IP. Typically this
|
|
module operates only on the REST API users and not the CLI users.
|
|
When specifying C(root), you may only change the password.
|
|
Your other parameters will be ignored in this case. Changing the C(root)
|
|
password is not an idempotent operation. Therefore, it will change it
|
|
every time this module attempts to change it.
