That's a know issue on the net-ldap library (ruby-ldap/ruby-net-ldap#44).
I believe it is fixed on version 0.4.0 of the library.

You can try changing the redmine's Gemfile with the following, do a bundle update and try it again:

Optional gem for LDAP authentication

group :ldap do
gem "net-ldap", "~> 0.4.0", :git => "https://github.com/ruby-ldap/ruby-net-ldap.git"
end

If it fixes the problem you can try suggesting the upgrade at redmine.org.

I've done a quick test on my redmine server and it seems like this version doesn't break the normal ldap authentication.

Thanks a lot for quick reply.
That did the trick!

I couldn't be able to start the Redmine after that tho, because Bundler complained:

/var/lib/gems/1.9.1/gems/bundler-1.2.3/lib/bundler/source.rb:801:
in `rescue in load_spec_files': 
  https://github.com/ruby-ldap/ruby-net-ldap.git (at master) is not checked out. 
Please run `bundle install` (Bundler::GitError)

I found this alternative source:
http://rubygems.org/gems/net-ldap-1

which works OK!

Thanks a bunch!
You did a great tool

Is this change now pulled into master?

from redmine_ldap_sync.

There was no change on the plugin.

You need to update Gemfile on redmine. I can't include the net-ldap-1 v0.4.0 on the plugin.
A ticket has to be opened on redmine for this change to be permanent.

Is there a redmine issue i can vote to update net-ldap. I have same problem for novell ldap server.

from redmine_ldap_sync.

Why can't u add GemFile here ?

source :rubygems
gem "net-ldap-1", "~>v0.4.0"

from redmine_ldap_sync.

Actually I haven't tried adding "net-ldap-1".

With "net-ldap" it raises a conflict and prevents redmine from starting.

There is no issue opened on redmine.org.

It turns out that, at least here, using net-ldap-1 allows everybody to log on Redmine with any password....

So one solution is to use net-ldap-1 only while syncing and returning orignal after (which requires restarting web server so it might not be an option in some cases).

I will try to use again the code suggested by thorin

from redmine_ldap_sync.

I can confirm it.
With net-ldap-1 the ldap authentication gets broken.
Any password becomes valid to login as any user.

That doesn't happen if you use the version provided on https://github.com/ruby-ldap/ruby-net-ldap.git.

I'll try to include a patch on for the utf8 problem in my plugin as planned on the redmine's ticket.

from redmine_ldap_sync.

I have included the patch on the plugin.
I'll need your help to test it, since I cannot reproduce the problem.

I'm giving preference to the fix proposed here: ruby-ldap/ruby-net-ldap@ccd7b6d
If it doesn't work I'll apply the one proposed here: https://github.com/ruby-ldap/ruby-net-ldap/pull/44/files

from redmine_ldap_sync.

I will test as sson as the bug #56 (comment) is removed.

from redmine_ldap_sync.

It looks like its fixed.
Thanks a lot.
