To use the net::ldap library with Jruby, you first need to install the gem by adding gem 'net-ldap' to your Gemfile and running bundle install.
Then, you can require the gem in your Ruby file using require 'net/ldap' and create a new LDAP object using ldap = Net::LDAP.new(:host => 'ldap.example.com', :port => 389).
You can then perform operations such as binding to the LDAP server, searching for entries, adding or modifying entries, and more using the methods provided by the net::ldap library.
Remember to handle errors appropriately and ensure that you have the necessary permissions to perform the desired operations on the LDAP server.

What is LDAP entry DN and how is it used to uniquely identify LDAP entries with net::ldap and jruby?
LDAP entry DN (Distinguished Name) is a unique identifier for an entry in an LDAP directory. It is a hierarchical naming structure that represents the full path to an entry within the LDAP directory tree.
In net::ldap, an LDAP entry DN is used as a key to uniquely identify and manipulate entries within an LDAP directory. It is used to search for entries, add, modify or delete entries, and check for the existence of entries.
In JRuby, you can interact with LDAP directories using the net::LDAP library, which provides a set of classes and methods for working with LDAP directories. When working with LDAP entries, you can use the DN as a unique identifier to perform various operations on the entries within the LDAP directory.
To uniquely identify an LDAP entry using its DN in net::ldap and JRuby, you can utilize the DN as a parameter in methods such as search, add, modify, and delete. For example, when searching for an entry, you can specify the DN in the search filter to retrieve the specific entry you are looking for. Similarly, when adding, modifying, or deleting an entry, you can use the DN to identify the entry that needs to be manipulated.
Overall, the LDAP entry DN is an essential component in working with LDAP directories in net::ldap and JRuby, as it allows for the precise identification and manipulation of entries within the directory.
What is LDAP referral and how is it used to handle searches across multiple LDAP servers with net::ldap and jruby?
LDAP referral is a process in which a LDAP server can refer a LDAP client to another LDAP server when the requested information does not exist on the referring server. This helps in handling searches across multiple LDAP servers seamlessly.
In net::ldap, a Ruby gem that provides an object-oriented interface for accessing and manipulating LDAP directories, referral handling is done automatically when it encounters a referral response from the LDAP server. When a referral is received, net::ldap will automatically follow the referral and send the search request to the referred server.
To enable referral handling in net::ldap, you need to set the :allow_referral option to true when initializing the Net::LDAP object. This will ensure that net::ldap will automatically follow referrals from the LDAP server.
Below is an example of how referral handling can be enabled when using net::ldap with jruby:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 |
require 'net/ldap' ldap = Net::LDAP.new( host: 'ldapserver', port: 389, base: 'dc=example,dc=com', auth: { method: :simple, username: 'cn=admin,dc=example,dc=com', password: 'password' }, allow_referral: true ) ldap.search(filter: '(objectclass=*)', scope: Net::LDAP::SearchScope_WholeSubtree) do |entry| puts "DN: #{entry.dn}" entry.each do |attribute, values| puts " #{attribute}:" values.each do |value| puts " --->#{value}" end end end |
In this code snippet, we have enabled referral handling by setting the allow_referral option to true when initializing the Net::LDAP object. This will allow net::ldap to automatically follow referrals and search across multiple LDAP servers.
What is LDAP search scope and how is it used to define the search boundary with net::ldap and jruby?
LDAP search scope refers to the scope of the search operation within the LDAP directory tree. It defines what part of the directory tree should be searched during an LDAP search operation. There are three common LDAP search scopes:
- Base: The search is limited to a single entry (or object) in the directory tree.
- OneLevel: The search is limited to the immediate children of a specified entry in the directory tree.
- Subtree: The search is conducted throughout the entire subtree below a specified entry in the directory tree.
In net::ldap with JRuby, you can use the search scope parameter in the search method to define the scope of the LDAP search operation. For example:
1 2 3 4 5 6 7 8 9 |
require 'net/ldap' ldap = Net::LDAP.new ldap.host = 'ldap.example.com' ldap.port = 389 ldap.auth 'username', 'password' scope = Net::LDAP::SearchScope_Subtree result = ldap.search(:base => 'dc=example,dc=com', :filter => '(objectclass=*)', :scope => scope) |
In the above example, we specified the LDAP search scope as 'Subtree' by setting the :scope parameter to Net::LDAP::SearchScope_Subtree. This means that the search operation will be conducted throughout the entire subtree below the base entry 'dc=example,dc=com' in the LDAP directory tree.
By using the LDAP search scope parameter, you can easily define the search boundary and control the scope of the search operation in your LDAP application.
What is LDAP schema and how does it define object classes and attributes with net::ldap and jruby?
LDAP schema is a set of rules that define the structure of the information that can be stored in an LDAP directory. It specifies the object classes and attributes that can be used to represent different types of data in the directory.
In net::ldap and jruby, the LDAP schema is typically defined using LDIF (LDAP Data Interchange Format) files. These files contain descriptions of object classes and their attributes, including their names, data types, and any restrictions on their usage. The schema can also include information about inheritance relationships between object classes.
When using net::ldap and jruby to interact with an LDAP directory, the schema is used to validate the data that is being submitted to the directory. This ensures that only valid object classes and attributes are used, and helps to maintain the integrity of the directory.
Overall, the LDAP schema plays a crucial role in defining the structure of an LDAP directory and ensuring that data is stored and retrieved in a consistent and reliable manner.
