DuoOIDC InvalidPathException Illegal char <*> at index 9: classpath*:\net\shibboleth\idp\plugin\authn\duo\duo-client-factory-bean.xml

[Cantor, Scott]

This is Windows being Windows, and no, it's not going to get reverted, it's a necessary behavior.

We use the same syntax all over the place so I doubt it's as simple as just that one issue. It shouldn't even start up without the plugin. So something else is probably going on, possibly just as simple as using the drive letter that way.

I don't know whether it's possible to get it to work on Windows or not, but your best option is to never use a non-default location for the IdP. Whatever has to be done to ensure that is the best choice most of the time. Use a symlink if you have to.

Either way, please file a bug.
