Hi
It looks like someone told you "it needs to be hashed" and then you
applied the 'hash' filter with ansible.
But there are many subtleties when it comes to hashing, even more so
with password hashing, and yet more because applications may expect
something specific/dialect.
I have no idea what "Traefik" is - you should look at their docs,
those should tell you exactly what its expects.
However, given that you mentioned that the {SHA} style password works,
and you also mentioned "basicauth", it might be the "standard" LDAP
SHA1, so try that:
user_combinehash: "{{ username_auth }}:{{ user_password | hash('ldap_sha1') }}"
This is all part of the docs BTW
(https://docs.ansible.com/ansible/latest/user_guide/playbooks_filters.html#hashing-filters).
Definitely read this:
"Hash types available depend on the master system running ansible,
‘hash’ depends on hashlib password_hash depends on passlib
(https://passlib.readthedocs.io/en/stable/lib/passlib.hash.html)."
