User auth against an IMAP server - is it wanted?

Added by Tim Jones over 14 years ago

After some fiddling I have managed to integrate Redmine into my company server setup. In this setting all basic user auth is done against an IMAP server and I have now gotten this working well with Redmine.

I was just wondering, is this a feature that would be wanted by other people? If so, I will try and turn it into a patch/plugin to complement the LDAP auth that already exists.

I don't need it, but if you touch things around here I'd be glad if could also
add simpler support for active directory authentication.

If found out that changing the line below allows me to authenticate against
our ADS without a predefined "readonly" account.
However one must have the DOMAIN configures as shown below. Of course this
should be a setting for this ldap service - but I don't know enough to
do that myself.

app/models/auth_source_ldap.rb

  1. get user's DN
    #ldap_con = initialize_ldap_con(self.account, self.account_password)
    ldap_con = initialize_ldap_con("DOMAIN\\" + login, password) or return nil

I don't need it but it might be useful to someone if you build it into a plugin.

I would appreciate to have such a function natively in redmine or as plugin. This would be a very nice way to use e.G. Microsoft Office 365 accounts for redmine login as Microsoft Office 365 currently does not offer an external LDAP service.

It was a pity that Tim Jones did not contribute his IMAP authentiocation module.

For those want to centralize the user authentication with IMAP for Redmine, please use the module I contribute.
Attachment also available for download.

  1. Put the module to redmine/app/models/auth_source_imap.rb
  2. Check the comments to setup
  3. NO UI view for this module, hope someone to make it

Apache with IMAP authentication

Original from mod_auth_imap, I added Auth_IMAP_Domain option which can be used to login Google Apps. Once Auth_IMAP_Domain was set, login username will be an email address.

Check out the attachment, you need to run build.sh on Ubuntu.

Office365.com authentication. - Added by Thanos Politis over 10 years ago

After a few minor changes to Sunding Wei's code we managed to authenticate with the office365.com service.
