Hi, I have developed a thin front end client in PHP to enable CILogon authentication for Galaxy, and set up a dummy Galaxy instance demo at https://gw64.iu.xsede.org. Please let me know if this is of interest to anyone and I'd be happy share more details as well as the source. The choice of PHP instead of Python is because I was unable to find a good Python Oauth library that supports the RSA-SHA1 signature method required by CILogon's OAuth interface. Thanks Marie
