[web2py] CAS Auth with other technologies

[Bruno Bemfica]

Hi, I'm new on Web2Py and Python, and I have a question: There's any
way to make apps developed with other technologies (in my case, PHP
and ASP.NET) authenticate with the web2py CAS server? I need to
integrate some apps to my company and we have systems made in a lot of
different technologies. What we need is, for example: Login into the
web2py app, and if the user click in a link to an ASP.NET or PHP
application, he doesn't need to login again, and vice-versa.

Thanks!
