A server that runs the Active Directory Domain Services is the domain controller that validates and gives a go ahead to all users and machines in Windows domain network.This helps appoint and apply security codes for all machines and for installation or software update. So, if a user tries to log in to your Windows domain computer, Active Directory authenticates the password entered, identifies and differentiates between a system administrator and a regular user.Active Directory is specially developed to read a large number of modifications and updates made to your computer. However, there are quite a few third-party alternatives to Microsoft Active Directory nowadays that perform the same job while they offer a different kind of features.

It is certified by the Open Group n 2006 and also by the Eclipse based database utilities. Apart from LADP, Apache Directory also supports other codes along with Kerberos server.The eclipse based directory tool, Apache Directory Studio added by a subproject includes a schema browser, DSML editor, LDAP editor/browser, LDIF editor, etc.
An eclipse RCP application, the Apache Directory is made of several plugins based on Eclipse that can be conveniently upgraded with additional options.Open LDAP or LDAP Admin is a free and open-source application of the Lightweight Directory Access Protocol (LDAP) designed by the OpenLDAP project. It’s a Windows LDAP client and administration tool for LDAP database control. One of the best alternatives to MS Active Directory that is present for the administrator, Open LDAP lets you browse, look up, change, create and remove items on LDAP server. Some of the other functionalities offered by this project are scheme browsing, managing password, support for the binary attribute, export & import LDIF, and more.Univention Corporation Server is a server software that is used for profitable operations and convenient control of server applications and complete IT operations. You can find only the latest version on the Oracle website. The fact that the original product, Sun Java System Directory Server had many issues with the C language and hence, it started with the OpenDS in 2011.
And since then the code base has not yet been updated.IBM Tivoli Directory Server is an IBM implementation of the LDAP or the Lightweight Directory Access Protocol. It is a directory especially designed for the enterprises that target the corporate intranet and the Internet.
For faster development and distribution of identity control, security and web application initiatives by adding robust management, impression and security features, the BM Security Directory Server is built in to meet the needs.This server includes multiple validation methods that are beyond just usernames and passwords.

When you want to set up an application, most likely you will need to create an administrative account and add users with different privileges. This scenario happens frequently with content management, wiki, file sharing, and mailing lists as well as code versioning and continuous integration tools. When thinking about user and group centralization, you will need to select an application that fits your needs.If the application can connect to a Single Sign On server, users will be happy to remember only one password.In the proprietary landscape of directory servers, Active Directory is the dominant tool, but there are directory servers that can also satisfy your needs. The protocol is the base for all the directory servers, independently of how they are implemented. This protocol is an industry standard and allows you to create, search, modify, and delete your users or groups.
And, if the application is able to connect to an LDAP server, you will not have to be concerned with understanding the protocol.

With OpenLDAP you can secure the communication and define privileges for your users. Being a command line tool, you can consider setting up, which is a web application that allows you to see and modify the structure of your organization within your browser. If you find setting up and configuring OpenLDAP difficult, you may find ApacheDS and OpenDJ easier as they are both LDAP servers running on Java.
ApacheDSrespects the latest version of the LDAP protocol, and it is released under the Apache license. Although you can use the OpenLDAP command line, ApacheDS is shipped together with, a client application, which allows you to easily manage your users and groups. For the setup, ApacheDS provides different installers for Windows, Mac OS X, and Linux. Further, if you are looking for an open source Identity Server, you might discover that the has ApacheDS built in to manage users.
OpenDJis a fork of former project, and has similar roots as the Oracle Unified Directory, as it was inherited from Sun Microsystems. After Sun was acquired by Oracle in 2010, OpenDJ was designed to replace Sun Directory Server. OpenDJ is released under the CDDL license and, like OpenLDAP, has good documentation. OpenDJ is in active development, and ongoing activity is reflected in the.
The OpenDJ team provides not only a to manage the server but also, which provides Single Sign On, authorization, federation, and more. 389 Directory ServerThe server is a Red Hat product (also provided under the name Red Hat Directory Server on top of the Red Hat Enterprise distribution). It is mostly licensed with GPL, having other components under different licenses. The directory server is in active development and it is packaged for Fedora and Red Hat distribution although you can obtain it for other Linux distributions as well. The 389 Directory Server has also a that can be used for administration. If you need more services like Certification Autority and authentication and integration with Active Directory check out which is based on 389., and server all allow you to establish secure communication and define privileges for your users; they also have strong encryption methods for storing user passwords.
No mention of FreeIPA? Admittedly, the LDAP implementation is 389 Directory Server, but if you're discussing GUI tools and Active Directory it seems like a good fit. IPA installation is extremely easy, comes with an HTML management GUI, and gives you useful pre-integrated services like Kerberos, a CA, optional management of your DNS, and so-on. For most people who might consider deploying a new directory, it should be a strong contender.
I think it's easier and more full-featured than anything mentioned in the article. Hello Brandon,LDAP is well famous and stabile protocol that is used a lot at corporate level, many software like Drupal, Jenkins, Nexus, Owncloud, Atlassian Suite, Redmine, Apache, PAM, Postfix support it. Of course there can be new protocol around, for example rest api, but the concept is always the same. The difference among various software is the level of extension they provide, for example ApacheDS and OpenDj support various password encryption methods which could be one of your requirements if previously you saved password in a particular format and you don't want ask your users to change their password as soon as an ldap server installed. For me Ldap is the natural choice as soon as new software need to be installed since only few of them can act as Single Sign On client so you want make sure at least user centralization. I use openLDAP and Samba3 for single sign on.
With the help of smbldap tools, we can start loading the openLDAP with a structure for windows login (need to add samba schema to the openldap schema directory), etc. Each time I want to create a new user or group, I utilize smbldap tools (smbldap-useradd / smbldap-groupadd) since it's 'safer' to use than phpldapadmin and it's more flexible (we can add/del hundreds of users via a bash script). For the operation team - the non-techy person - I give them phpldapadmin. It's been running for almost 10 years now on an openSuSE server.
