Hi All,

 

I am trying to port mahara authentication to SAML.

I finished setting the requirements for the plugin, but having issues filling the field required on the wizard for the SAML.

Does anyone has notes for how to do the config on the plugin.

Hi Guys,

 

I made some progress and put a custom field "eduPersonOrgDN" on the IDP to pass to the mahara to find the institution "Institution attribute". So i am able to create the saml2 authentication plugin configuration.

 

the issue is when i try to login i get these errrors:

[WAR] 0d (auth/saml/extlib/simplesamlphp/vendor/robrichards/xmlseclibs/src/XMLSecurityKey.php:563) openssl_sign(): supplied key param cannot be coerced into a private key

Please has anyone stumbled on this error before?

Hi Tim,

What version of SAML are you using? Currently, Mahara doesn't support SAML 2.x yet.

Cheers

Kristina

Hi Kristina,

I'm using SAML 2022020100, and has the same issue as Tim, may I know if this is any solution in the current state? Thanks.
