delagate_to ignores --user parameter

[kustodian]

I'm using the latest master version from Git on Archlinux (Python 3.7.0) and CentOS 6 (Python 2.6.6) as target host.

I have the following task:

- name: 'Create Postgres user for zabbix-server'
  postgresql_user:
    name: '{{ zabbix_server_dbuser }}'
    password: '{{ zabbix_server_dbpassword }}'
    role_attr_flags: 'LOGIN'
    port: '{{ zabbix_server_dbport }}'
  delegate_to: '{{ zabbix_server_db_hostname }}'

which fails like this:

zabbix_server_db_hostname is set like this:

zabbix_server_db_hostname: "{{ inventory_hostname }}"

I run the playbook with:

[myuser@host] $ ansible-playbook -i hosts.ini zabbix.yml -u root

As you can see from the error, it uses myuser to ssh into delegate_to host, instead of root.

If I set ansible_user=root in inventory for the zabbix host, everything works fine.

Here is the ansible configuration diff if you need it:

Hi there, sorry for the crazy delay. There was a huge delegate_to bug introduced mid last year that made it into 0.2.3. It seems to have caused all these problems.

This should now be fixed on the master branch and will make it into the next release. To be updated when a new release is made, subscribe to https://networkgenomics.com/mail/mitogen-announce/

If you are still experiencing the problem on the current master branch, please do not hesitate to reopen this issue.

Thanks for reporting this!
