However they generally come pre-installed with the system and Ansible will require they are present at runtime. If they are not, a descriptive error message will be shown. - On SunOS platforms, the shadow file is backed up automatically since this module edits it directly. On other platforms, the shadow file is backed up by the underlying tools used by this module. - On macOS, this module uses C(dscl) to create, modify, and delete accounts. C(dseditgroup) is used to modify group membership. Accounts are hidden from the login window by modifying C(/Library/Preferences/com.apple.loginwindow.plist). - On FreeBSD, this module uses C(pw useradd) and C(chpass) to create, C(pw usermod) and C(chpass) to modify, C(pw userdel) remove, C(pw lock) to lock, and C(pw unlock) to unlock accounts. - On all other platforms, this module uses C(useradd) to create, C(usermod) to modify, and C(userdel) to remove accounts. - Supports C(check_mode). seealso: - module: ansible.posix.authorized_key - module: ansible.builtin.group -
