[ckan-dev] ERROR: The authenticate attribute was not provided.

[Florian May]

Hi,

I'm stuck with the same problem. repoze.who 2.0 and 2.2 both throw
ValueError: auth_tkt: An object has failed to implement interface
<InterfaceClass repoze.who.interfaces.IAuthenticator>

I'm experiencing this with versions after the repoze.who upgrade on Nov 12.
Would anyone have any pointers?

Cheers,
Florian
