<p><span lang="EN-US">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?<o:p></o:p></span></p>
