[Zope] using zExtraExAuths w/ exUserFolder for IMAP auth

[Shawn Grant]

I'm using zope 2.4.2, python 2.1.  Trying to setup IMAP authentication 
using zExtraExAuths.  exUserFolder seems to working properly on its own 
for me with the Authentication sources it comes with.

When I choose IMAP Authentication source I get the following error. 
 Anyone using this product?  Any ideas?

*Error Type: NameError*
*Error Value: name 'currentAuthSource' is not defined*
