Redmine

You just have to customize the following file: plugins/redmine_ldap_sync/lib/tasks/ldap_sync.rake

Currently the task looks like:

desc "Synchronize redmine's users fields and groups with those on LDAP" 
      task :sync_users => :environment do |t, args|
        init_task   
        AuthSourceLdap.activate_users! unless ENV['ACTIVATE_USERS'].nil?
        AuthSourceLdap.all.each do |as|
          trace "Synchronizing '#{as.name}' users..." 
          as.sync_users
        end
      end

The fast and dirty way to achieve this is to add a check if as.name equals yourusername and execute the task 'as.sync_users' just if that check passes. This works the same for groups...

Should look like:

if as.name == "yourusername" 
    as.sync_users
end

I am also new to Ruby/Rails. Let me know if it works & Happy Easter,
