There are 2 known issues which breaks token auth method in CLI: * The wrong check of flag (the check should be for --os-token since arguments are not parsed at that moment) is performed in CLI inner method `_append_global_identity_args`. It led to usage of "password" auth type by default[1] even if `--os-token` cli argument is specified. If `--os-auth-type` is specified to token, keystoneauth1 library makes the right decision[2]. * Based on an auth type, keystoneauth library registers different CLI arguments[3]. It means that `--os-username` argument is available only in password auth type, `--os-token` is available only in token auth type, etc. It also affects the way in which the python code should access such arguments. The arguments which are unrelated to the selected auth type are omitted from the parsed arguments object. That sounds reasonable, but unfortunately the code assumes the unrelated arguments are always present which leads to an AttributeError. Combination of these 2 issues made token auth type broken in CLI layer.
