The 'pluggable' functionality only allows one passdb at a time for
access via the existing interface.  I assign a static variable that
contains a pointer to the context that is initialised at startup.

However, I have allowed for muliple passdb backends to operate at the
same time when they create their own context.  This is designed for
things like a samcopy utility, which will know how to open two passdbs
at the same time.
