net-ldap authentication format in rails? - 


 def authenticate(username, password)         require 'net-ldap'         ldap = net::ldap.new         ldap.host = 'server.local'         ldap.port = 389         ldap.base = 'cn=users, dc=server, dc=local'         ldap.auth username, password         if ldap.bind             puts "authentication succeeded"             else             puts "authentication failed"         end

the above code use in method , not sure why attempts fail. trying authenticate user. not find going wrong? puts authentication failed every time. why? please me.

first see if computer using can talk ldap server

telnet server.local 389

obviously want replacing server.local actual server details. if can't log server way port 389 isn't open , may need running on ssl port 636. try previous command 636 rather 389 see if case.

if unable telnet server on either of ports you've either got firewall rule blocking talking it, ldap configured on non standard port or else wrong.

a working port 636 mean need run following.

require "net-ldap" ldap = net::ldap.new(     host: "server.local"     port: 636     encryption: :simple_tls ) ldap.auth username, password

failing of error message going pretty useful try running 

if ldap.bind     # yay! else     puts ldap.get_operation_result end

with results maybe can bit more.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
