Random related question. If you're writing a SAML implementation have
you found an XML Signature implementation that works reliably from
python? I've had a hell of a time finding something that doesn't
segfault and is interoperable with .NET.
As far as your problem goes, I would guess that somewhere you've got a
class named SAML that's shadowing your module. See the difference in the
error messages:
Python 2.5.2 (r252, Oct 31 2008, 10:47:40)
[GCC 4.1.2 (Gentoo 4.1.2 p1.1)] on linux2
