[Zope] Authentication issue with UserDB in 2.1.6?

[Tony McDonald]

Hi,
I've just updated an old 2.1.3 site to 2.1.6 using the 
Zope-2.1.x-to-2.1.6-src.tgz file.

Now I find that my docLogin screens in UserDB objects have 'Zope 
Error', 'LoginRequired' headings and the usual blurb you'd expect 
from a Zope Error.

Is this a known issue with UserDB and 2.1.6? The CHANGES log mentions 
a og of authentication and acquisition changes but nothing specific 
to this situation.

I use UserDB *stacks* so if anyone has any clues....

TIA
Tone
