Your patch is ok, that’s what I did by superseding the variable “keystone_apache_modules”.

Ansible -vvv trace shows that the task parameters are correct, but the apache shib module remains enabled. Anyway, authentication still fails and I get “valid-user: denied” in apache logs because of a weird interference with libapache2-mod-shib package.

For now, the workaround I’ve found is not to install the libapache2-mod-shib package:

“openstack-ansible os-keystone-install.yml --extra-vars '{"keystone_sp_distro_packages":["libapache2-mod-auth-openidc"]}'”

And everything works fine (if you don’t need shibboleth), keystone deployment and openid auth. But this is just a workaround.

I've made a patch to correct this module name which it would be great if you could test and leave a comment if it's OK

https://review.opendev.org/c/openstack/openstack-ansible-os_keystone/+/790018

Are you able to debug any further why the shib module is being enabled, maybe through using -vv on the openstack-ansible command to show the task parameters, or adding some debug tasks in os_keystone to show the values of keystone_sp_apache_mod_shib and keystone_sp_apache_mod_auth_openidc?

I forgot to mention: in Ubuntu 20.04, the apache shibboleth module is named "shib" and not "sib2". So, I had to supersede the variable
" keystone_apache_modules". If you don't do this, os-keystone playbook fails with " "Failed to set module shib2 to disabled:\n\nMaybe the module identifier (mod_shib) was guessed incorrectly.Consider setting the \"identifier\" option.", "rc": 1, "stderr": "ERROR: Module shib2 does not exist!\n"".
 
So, apache modules enabled are:
- shib
- auth_openidc
- proxy_uwsgi
- headers

Could you check which apache modules are enabled?
