Just a heads up that I just pushed django-impersonate 1.9.5 to pypi.  
This adds support to impersonate users when the User model has a UUID as 
the primary key.

https://pypi.org/project/django-impersonate/1.9.5/

This implements ticket #44[0]. Thanks to Adam Taylor for the patch[1] to 
implement it.
