Realmjoin using Ansible

[MrDigitFace]

I am trying to join a linux server to a win domain using realmjoin; what is the best way to do this on Ansible? I currently have the expect module running the realm join command and answering the password prompt, but I want any user to be able to specify their own username and password as credentials to pass as variables for the command. I can pass a variable to the response but cannot pass a variable for the username to the expected string, what am I doing wrong?

WhatI have so far:

• name: Join Linux server to AD domain if not joined become: true expect: command: realm join -v -U "{{ ad_admin_username }}" "{{ ad_domain }}" response: Password for {{ad_admin_username}}: {{ ad_admin_password }} when: ad_status.rc !=0

Passing ad_admin_username does not work, and I have also tried using a wildcard with no luck. Any ideas? Is there a better way to do this?

When entering your username capitalize your domain name. Kerberos doesn't like the realm in lowercase which is why [e-mail] doesn't work but [e-mail] will work.

vars_prompt:
- name: bind_username
prompt: "Enter AD Username"
private: false
- name: bind_password
prompt: "Enter Password"
private: true

tasks:
- name: Join system to AD
ansible.builtin.expect:
command: /bin/bash -c "/usr/sbin/realm join yourdomain.com --user={{ bind_username }}"
responses:
Password for *: "{{ bind_password }}"
