-u not being set when running ad-hoc ansible run?

[John Miller]

Hello everyone,

I'm trying to run the following ad hoc ansible command to run the date command remotely against an IP camera running Linux:

myuser@myhost:$ ansible camera.site.example.org -i /path/to/inventory -u root -k -m raw -a date

and receiving the following error:

camera.site.example.org | UNREACHABLE! => {
    "changed": false,
    "msg": "Invalid/incorrect password: Permission denied, please try again.",
    "unreachable": true
}

Running with -vvv seems to suggest that the -u root option is not being applied:

myuser@myhost:$ ansible -vvv camera.site.example.org -i /path/to/inventory -u root -k -m raw -a date
ansible 2.9.3
  config file = /etc/ansible/ansible.cfg
  configured module search path = [u'/home/myuser/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python2.7/site-packages/ansible
  executable location = /usr/bin/ansible
  python version = 2.7.5 (default, Aug  7 2019, 00:51:29) [GCC 4.8.5 20150623 (Red Hat 4.8.5-39)]

}

If I run the ssh command listed outside of ansible, substituting "root" for "myuser", things work fine:

myuser@myhost:$ ssh -C -o ControlMaster=auto -o ControlPersist=60s -o 'User="root"' -o ConnectTimeout=10 -o ControlPath=/home/myuser/.ansible/cp/22d4672695 -tt camera.site.example.org date
root@camera.site.example.org's password:

myuser@myhost:$

Any idea why the -u option isn't being passed to the underlying ssh command?
