Hi,

I've been using Redmine with LDAP (AD) auth for years and I have to say it's been working great so far. Now I'm in the process of migrating some of our systems to the cloud and it'd be great if Redmine was one of those. Now of course comes the problem of auth because AD is hosted on-premises.

It's trivial to sync the credentials to Azure AD and Since Redmine already supports LDAP, it may be a logical next step to add support for Azure AD that also supports the OpenID and OAuth standards.

There are plenty of resources for doing this:

What do you guys think?
