I would like to see a way to add a custom external authenticator. Currently, the "New Authentication Modes" link assumes an LDAP source. Some more information about what I'm trying to do is here: http://www.redmine.org/boards/1/topics/show/495

Once you subclass AuthSource, there should be a way to make it visible to React so that it can be selected in the Authentication administration page.

This is also required for kerberos authentication.

If the application run under apache, it should be able to receive the user from environment.

This is simple, as I don't know ruby I cannot promis it is the best solution.
But you can have configuration option for a request variable to take the user from.
In order to support basic authentication (kerberos or SSL) under apache with mod_rails, I only had to do the following:

   # Returns the current user or nil if no user is logged in
   def find_current_user
+    if request.env["REMOTE_USER"]
+      ( User.find_by_login(request.env["REMOTE_USER"]) rescue nil)
-    if session[:user_id]
+    elsif session[:user_id]
       # existing session
       (User.active.find(session[:user_id]) rescue nil)

As [1] wanted to have a different variable... So I guess the actual string may be configurable.

This is very important for enterprise deployment, please set milestone.

Very much agree.

We use this together with mod_auth_kerb

#5 Updated by Renno Reinurm over 13 years ago

I'm also interested to have external authentication support using Kerberos.

#6 Updated by Anthony Topper about 13 years ago

I'd like to see Kerberos support added as well.

#7 Updated by Stanislav German-Evtushenko over 12 years ago

I'm agree. It would be nice to be able to use Kerberos authentication.

#8 Updated by Brian Wells over 12 years ago

I've added a custom external authenticator to Redmine by means of a plugin that modifies the Authentication Sources view to include something other than LDAP.


It would be helpful if there was a more standard way to add a subclass of AuthSource and a custom form for it, but what I've done so far works fine.

I've change AuthSource so it can now be extended to support other external auth sources (i.e. removed the LDAP assumption). An example of how to add a new AuthSource can be seen in my redmine_sso_client plugin. It adds a new AuthSource model, controller, form, and a menu item.
