Connecting to an External LDAP Server SSSD on RHEL7 1. On server1, set up hostname resolution so that the LDAP server labipa.example.com can be reached by its name. In this exercise, the IP address 192.168.4.200 is used for the LDAP server. Change this according to the setup you are using and enter the following line in the /etc/hosts file: 192.168.4.200 labipa.example.com If your server is already using 192.168.4.200 as the DNS server, you can skip this step. 2. Type yum group install -y "Directory Client" 3. As root, type authconfig-tui . In the text user interface that opens now, under User Information select Use LDAP, and under Authentication, select Use LDAP Authentication. Do not unselect any option that is selected by default authconfig help | grep ldap authconfig enableldap enableldapauth ldapserver=ldap://labipa.example.com ldapbasedn="dc=example,dc=com" enablemkhomedir enableldaptls update 4. In the next screen, you are prompted as to whether TLS should be used; see Figure 6.3. Select Use TLS, and then enter the server URL ldap://labipa.example.com . Make sure the base DN is set to dc=example,dc=com. Then click OK to continue. 5. You now see a message indicating that you need to copy the certificate of the CA that has signed the public key certificate of the LDAP server to /etc/openldap/cacerts. Open a root shell in a new terminal window and from this terminal, type: scp labipa.example.com:/etc/ipa/ca.crt /etc/openldap/cacerts 6. Open the configuration file /etc/sssd/sssd.conf with an editor, and in the [domain/default] section, add the line: ldap_tls_reqcert = never Next, use systemctl restart sssd to restart the sssd service. 7. Use su - ldapuser1 to verify that you now have access to users on the IPA server. On the IPA server, a user with the name lara has been created. You notice that you are logged in as this user.

The System Security Services Daemon (SSSD), available on nearly all Linux distributions, is fast becoming the Linux server authentication framework of choice. The SSSD is capable of implementing modern, scalable, secure and highly available authentication infrastructures. Linux administrators and enterprises alike have been waiting for the AD integration and agility the SSSD provides. The most innovative features include offline authentication, the concurrent use of multiple authentication methods against multiple back ends, and Linux server Active Directory participation approaching the compatibility of a domain member server. This session covers baseline Linux system and Active Directory preparation for the SSSD, the concepts of SSSD identity, authentication, and service providers, daemon configuration and operational tips learned in the trenches. This Tutorial session was delivered at SUSECON in November 2016, in Washington, DC. Session code: TUT85751
🤍 The SSSD project started as a deamon that allows to resolve users and groups in LDAP, but is gaining more features over time. In this talk, I would like to give an overview of the features SSSD has, with focus on what was introduced into the project in the last couple of years or the features we are working on now. In particular, I would like to show how SSSD allows the administrator to easily enroll a client into an Active Directory domain including access control with Group Policies, the options SSSD has for Smart Card authentication or the possibilities to manage secrets with SSSD. In future, we would like SSSD to also manage the local users, traditionally stored in /etc/passwd, which is another topic the talk would outline, at least to show what we are planning. The talk would also include live demo. No previous knowledge about SSSD is required. The presentation would be aimed at administrators and to some degree also Linux distribution or program developers. jhrozek

#ldap #ldapauth What is LDAP and Active Directory ? How LDAP works and what is the structure of LDAP/AD? In this video, I have discussed regarding LDAP, Active Directory, LDAP vs Active Directory, Structure of LDAP, How LDAP works, LDAP Authentication. GitHub: 🤍 LDAP in Java: 🤍 LDAP Updated: 🤍 What is LDAP? LDAP, the Lightweight Directory Access Protocol, is a mature, flexible, and well supported standards-based mechanism for interacting with directory servers. It’s often used for authentication and storing information about users, groups, and applications, but an LDAP directory server is a fairly general-purpose data store and can be used in a wide variety of applications How Does LDAP work? In short, LDAP specifies a method of directory storage that allows for adding, deleting, and modifying records, and it enables the search of those records to facilitate both authentication and authorization of users to resources. LDAP’s three main functions are: Update: This includes adding, deleting, or modifying directory information. Query: This includes searching and comparing directory information. Authenticate: The main authentication functions include binding and unbinding; a third function, abandon, can be used to stop a server from completing an operation LDAP Directory Information Tree LDAP organizes information in a hierarchical tree structure, referred to as a directory information tree (DIT). The LDAP DIT can vary based on the software or directory service you use; however, LDAP directories generally follow this tree structure, where entries without subordinates (users, for example) are leaves, and the root is the overarching entity that encompasses all the information within the directory. LDAP Authentication and Authorization The LDAP protocol both authenticates and authorizes users to their resources. The protocol authenticates users with a bind operation that allows the user to communicate with an LDAP directory, then authorizes the authenticated user to the resources they need if their input login information matches what’s listed for them in the database. 1.What Is LDAP Authentication ? LDAP authentication relies on a client/server bind operation, which allows the LDAP-ready client, referred to as the directory user agent (DUA), and the directory server, referred to as the directory system agent (DSA), to communicate within a secure, encrypted session. When authenticating against an LDAP server in an attempt to gain access to the database, the user is prompted to provide their username and password. If the values the user inputs into the client matches what is found in the LDAP database, the user is granted access by the LDAP server to whatever the IT resource may be. 2. What Is LDAP Authorization ? Once a user is successfully authenticated, they need to be authorized to the resource(s) requested. While different LDAP instances may structure and encode this slightly differently, this is essentially accomplished by assigning permissions with groups and roles in the directory.
#LDAP #CentOS #ActiveDirectory #Windows This video is a step-by-step guide to integrate or configure CentOS 7 or RHEL 7 with windows active directory LDAP server for authentication. In other words, Join the CentOS or RHEL system or machine on the windows domain controller so that the users can log in to the Linux system with AD credentials. While creating the users in AD, we can make a member of those users to specific groups. We can manage or control the permission or access level using the group so that we don't need to work on hundreds of users for permission or access level.

In this video, we explain the similarities and differences between LDAP and LDAPS. Read the full blog post: 🤍 Learn more about Cloud LDAP with JumpCloud: 🤍 Learn more about JumpCloud: 🤍 Try JumpCloud for free: 🤍 Resources and social media: Blog: 🤍 Community: 🤍 Facebook: 🤍 Twitter: 🤍 LinkedIn: 🤍 Transcript: When it comes down to it, LDAP and LDAPS are not fundamentally different protocols. They both make use of the lightweight directory access protocol for directory management and authenticating users to resources. The difference lies in the way that they transmit information. LDAPS is an extension of LDAP that encrypts its data transmissions. Here's how it works. LDAP was designed to transmit data in plain text using Port 389. Back in the early nineties when LDAP was invented, business was typically conducted over a closed LAN. This made transmitting data without encryption to and from the local LDAP server relatively safe because the transmissions were contained within the local network. However, as businesses started adopting the internet, and more recently the cloud, transmitting data in plain text began to pose security problems. With cloud-based LDAP, data including users' credentials can be sent to and from the LDAP server over the public internet. If that data isn't encrypted, it's at serious risk of theft or compromise. To solve for this, engineers designed a way to send LDAP communications over a cryptographic protocol called SSL. SSL uses certificates to establish a secure connection between the client and the server before exchanging any data. In other words, LDAP over SSL allows LDAP data to be encrypted in transit. This way, credentials and other data remain secure when being sent over the internet. This extension of LDAP that leverages SSL is referred to as LDAPS and it's accomplished with a new port, Port 636. LDAPS does everything that LDAP can do, the main difference is that it uses a more secure channel that encrypts data in transit. To summarize, LDAP and LDAPS are both forms of the Lightweight Directory Access Protocol, which is used to manage directories and authenticate and authorize users to resources. LDAP transmits data in plain text while LDAPS encrypts data in transit, which makes it a more secure form of the LDAP protocol. LDAP uses Port 389 while LDAPS uses Port 636. Now a note on SSL. SSL has been upgraded to TLS, which stands for Transport Layer Security. LDAP is also able to transmit over TLS. This method is called STARTTLS. Because STARTTLS uses an improved version of SSL, STARTTLS is generally considered even more secure than both LDAP and LDAPS. You should always use a secure form of LDAP, whether that's LDAPS, STARTTLS, or a combination of the two. Most LDAP providers offer secure LDAP and many require it. Check your LDAP provider's policies to make sure they use a secure form of LDAP. And if you host your own LDAP instance, make sure you're transmitting LDAP data over SSL or TLS.

OpenLDAP is a free implementation of LDAP and is used over a network to manage and access a distributed directory service, which can be used for things like PC logins. OpenLDAP is widely used because it’s cost-effective, OS agnostic and flexible. While OpenLDAP is powerful, it’s also complex. LDAP Account Manager (LAM) is a web frontend for managing entries (e.g. users, groups, DHCP settings) stored in an LDAP directory. The LDAP Account Manager tool was designed to make LDAP management as easy as possible for the user. LAM ease administration of LDAP entries by abstracting the technical details of LDAP and allowing administrators and users without technical background to manage LDAP server. If needed, experienced users can directly edit LDAP entries via the integrated LDAP browser. 📌Features of LDAP Account Manager ✅ Manages Unix, Samba 3/4, Kolab 3, Kopano, DHCP, SSH keys, a group of names and much more ✅ Has support for 2-factor authentication ✅ Support for account creation profiles ✅ CSV file upload ✅ Automatic creation/deletion of home directories ✅ Setting file system quotas ✅ PDF output for all accounts ✅ Schema and LDAP browser ✅ Manages multiple servers with different configurations 📌 Unlock more features with LDAP Account Manager pro edition, such as: ✅ Users being able to edit their own data (e.g. password, address, telephone numbers, …) ✅ Uses resetting their own passwords ✅ Support for users self-registration ✅ Support for custom LDAP schema ✅ Unix, Samba 3/4, Kopano, … ✅ Supports multiple self-service profiles (e.g. for different LDAP servers and/or use-cases) 📌 LDAP Account Manager Dependencies ✅ LDAP Account Manager has a number of dependencies, namely: ✅ OpenLDAP server: ✅ PHP and Apache web server ✅ A user account with sudo privileges
