We are looking for a solution which provides a webmail with modern UI and SAML integration with our Shibboleth deployment (SAML2) for users authentication. SOGo should support this authentication method by design and I used iRedMail for years in my previous job, so I back here to look for.
But I can't see anything about SAML Auth and iRedMail.

We are interested to a deployment of SOGo3 on CentOS 7, with SAML Auth on our Shibboleth deployment. New users could be created via API from our portal and also users initiated password updates could be managed via our portal and your API.

Can you see any critical issues on this scenario?
