Oh , my setting as below
==
authkit.setup.method = forward, cookie
authkit.cookie.secret = secret string
authkit.cookie.signoutpath = /auth/signout
authkit.forward.internalpath = /auth/signin
authkit.form.authenticate.user.object = authkit.users:UsersFromString
authkit.form.a
But I have a new question
when I write like this follow the tutorial
(http://pylonsbook.com/alpha1/authentication_and_authorization)
and write as below
"""
...
app = CacheMiddleware(app, config)
permission = ValidAuthKitUser()
app = authkit.authorize.middleware(app, permission)
...
