If you had to make a change to TurboGears itself then there is
something wrong in the way authentication is configured for your
application.
A working 2.2 authentication setup should look like:
base_config.sa_auth.cookie_secret = "ChangeME"
base_config.auth_backend = 'sqlalchemy'
base_config.sa_auth.user_class = model.User
from tg.configuration.auth import TGAuthMetadata
class ApplicationAuthMetadata(TGAuthMetadata):
[...]
base_config.sa_auth.dbsession = model.DBSession
base_config.sa_auth.authmetadata = ApplicationAuthMetadata(base_config.sa_auth)
base_config.sa_auth.form_plugin = None
base_config.sa_auth.charset = 'utf-8'
base_config.sa_auth.post_login_url = '/post_login'
base_config.sa_auth.post_logout_url = '/post_logout'
Nothing else should be required and might actually cause issues as
everything that is available inside sa_auth property is passed to
repoze setup and can actually change the way your authentication is
configured.
