Hi Kohuke,
Im the author of the original SAML plugin for Limesurvey that I created 6 years ago:
github.com/pitbulk/limesurvey-saml
It seems that some people took it and added some new features.
I had no access to the code of the version created by LimeSurvey GMBH so can't
say how complete it is.
I implemented 2 new versions:
- A version that keep using simpleSAMLphp and where I added new features.
- A version that uses php-saml instead of simpleSAMLphp which eliminates the session conflict issue and the ability to configure the IdP directly on Limesurvey admin settings (you can only connect 1 IdP for now, but if the plugin become popular I plan to support there multiple IdPs).
I plan to sell it on LimeStore, but for now since marketplace seems not mature, I plan to sell it by Paypal for now.
I gonna sell it for 100€ and early adopters will receive free support.
Later, I plan to join the yearly subscription, and maybe I reduce the price.
Early adopters will be added to the annual fee scheme, but maybe I exclude them from the first payment.
If you interested, message me sixto.martin.garcia+limesurvey@gmail.com.
