Fixes the problem for me, but I agree with Rob re globals - a
context manager would be much nicer.  Something like (pseudocode):

    @contextlib.context_manager
    def private_ccache():
        ... stuff currently in init_private_ccache()
        yield
        ... stuff currently in destroy_private_ccache()

Then in ipa-server-install main():

    with private_ccache:
       if not options.uninstall:
           server.install_check(options)
           server.install(options)
        else:
           server.uninstall_check(options)
           server.uninstall(options)

Cheers,
Fraser
