SAML Plugin for Redmine 5.0

Hi All,

I'm a bit new to this forum and I would like to know if there is any SAML plugin for Redmine 5.0? I have tried this https://github.com/chrodriguez/redmine_omniauth_saml but it gives an error while trying to install.

This is the error I'm getting.

RE: SAML Plugin for Redmine 5.0 - Added by Nicolas Metters 5 months ago

Dupplicate of #68351

Late reply but for whoever is looking for information:

The SAML plugin has been updated and works out of the box for me plugin version 1.0.6 on Redmine 5.0.5 :
https://github.com/omniauth/omniauth-saml#options

The error "LoadError: cannot load such file -- redmine_omniauth_saml" is probably from a change in syntax in the way init.rb calls files

<quote>require 'redmine'
require 'redmine_omniauth_saml'
require 'redmine_omniauth_saml/hooks'
require 'redmine_omniauth_saml/user_patch'
</quote>

For it to work with Redmine 5.XX, it must be updated to the new format such as:
<quote>require 'redmine'
require File.expand_path('redmine_omniauth_saml', dir)
</quote>

This will load the DIRectory so includes all 3 lines "require 'redmine_omniauth_saml"

For whoever it could interrest: I've documented the SAML plugin configuration in Redmine 5.0.5 using Keycloak v22
