Okay, took me a while to realize what's going on... in alpha2 we were
still running the server under mod_python (we have since switched to
mod_wsgi).

In alpha2, when ipaserver is imported, ipaserver/__init__.py tries to
import mod_python (which would indicate we are running under the Apache
process).  When mod_python could be imported, we always initialized IPA
for use in the server.  The worked fine for us at the time, but it
obviously causes problems when trying to use the library from another
mod_python handler.

I recommend you try working with the current code from git, where this
implied initialization has been removed:

    git clone git://git.fedorahosted.org/git/freeipa.git

I attached a script that I use to install a bunch of dependencies for
building the rpm (or srpm).

After you have these dependencies installed, you can then build and
install ipa doing something like this:

    cd freeipa
    make rpms
    yum install --nogpgcheck dist/rpms/*.rpm
    ipa-server-install


Hope this helps!
