google app engine - python SAML in GAE -

-

is there library can use saml authentication in app engine using python?

i've looked @ pysaml2 it's pure python implementation. however, it's using subprocess.popen cannot used within app engine , fail @ point.

you can use python-saml on gae if use flex environment custom runtime built off of standard python27 runtime provided google. got onelogin's python-saml flask-demo working approach using following settings:

dockerfile:

from gcr.io/google_appengine/python label python_version=python run virtualenv /env -p python  # install system packages onelogin dependencies not included in runtime run apt-get update && apt-get --yes --quiet install python2.7-dev libxmlsec1-dev  # set virtualenv environment variables. equivalent running # source /env/bin/activate env virtual_env /env env path /env/bin:$path add requirements.txt /app/ run pip install -r requirements.txt add . /app/ cmd python index.py

app.yaml

runtime: custom env: flex entrypoint: python index.py  api_version: 1 threadsafe: true

requirements.txt

flask==0.10.1 python-saml

then gcloud app deploy app.yaml --version v1
