Convert multiple X509 DN strings into a consistent format.

Add this line to your application's Gemfile:

gem 'dnc'

And then execute:

$ bundle

Or install it yourself with:

$ gem install dnc

To create a DN instance:

require 'dnc'
dn = DN.new(dn_string: '/C=US/OU=string/O=DN/CN=Some Valid')
# Or:
dn = '/C=US/OU=string/O=DN/CN=Some Valid'.to_dn
dn = '/C=US/OU=string/O=DN/CN=Some Valid'.to_dn!

To return a consistently formatted string:

dn.to_s
#=> 'CN=SOME VALID,O=DN,OU=STRING,C=US'

This is what a basic DN object looks like:

puts dn.to_yaml
#=>
--- !ruby/object:DN
dn_string: CN=SOME VALID/O=DN/OU=STRING/C=US
original_dn: "/C=US/OU=string/O=DN/CN=Some Valid"
logger: !ruby/object:Logging::Logger
  [... snipped ...]
transformation: upcase
delimiter: "/"
cn: SOME VALID
o: DN
ou: STRING
c: US
string_order:
- cn
- l
- st
- o
- ou
- c
- street
- dc
- uid

There are multiple parameters you can pass in to modify the DN's formatting:

• dn_string: REQUIRED The DN string you want to parse into a DN object.
• transformation: upcase, downcase, to_s (or any valid String method).
• delimiter: Custom delimiter, DN auto detects if possible, but this forces it.
• string_order: DNC returns RDN elements as per LDAP specs (RFC4514), but to customize it you can send an array (of strings) to sort your .to_s results.
  The default order is: %w(cn l st o ou c street dc uid)
• logger: Custom logger, defaults to Rails logger or Logging gem logger.
