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.

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?
