What is the difference between SSSD and LDAP?
An SSSD based solution can pick the closest Active Directory server based on site affiliation. In the case of simple LDAP, there is usually just one server and no discovery or site affiliation.
Can SSSD authenticate against multiple Active Directory domains?
SSSD can use more than one domain at the same time, but at least one must be configured for SSSD to start. Using SSSD domains, it is possible to use several LDAP servers providing several unique namespaces.
Does SSSD use LDAP?
The System Security Services Daemon (SSSD) is a daemon that manages identity data retrieval and authentication on a RHEL host. A system administrator can configure the host to use a standalone LDAP server as the user account database.
Does SSSD use Kerberos?
SSSD assumes that the Kerberos KDC is also a Kerberos kadmin server. However, it is very common for production environments to have multiple, read-only replicas of the KDC, but only a single kadmin server (because password changes and similar procedures are comparatively rare).
What is SSSD IPA?
SSSD is an acronym for System Security Services Daemon. It is the client component of centralized identity management solutions such as FreeIPA, 389 Directory Server, Microsoft Active Directory, OpenLDAP and other directory servers.
What is the SSSD conf file?
The “[sssd]” section is used to configure the monitor as well as some other important options like the identity domains. Indicates what is the syntax of the config file.
How do I use Sssd?
Install and Configure SSSD
- Install sssd. yum install sssd.
- Make sure permissions on the sssh. conf file are correct.
- Update the /etc/nsswitch. conf file to retrieve Posix attributes from the LDAP server.
- Configure PAM to use sssd.
- Restart the sssd daemon to pick up the configuration changes.
What is SSSD client?
The System Security Services Daemon (SSSD) is a system service that allows you to access remote directories and authentication mechanisms. You can connect a local system, an SSSD client, to an external back-end system, a provider. For example: An LDAP directory.
What is SSSD used for?
What port does SSSD use?
Below is a table that summarizes the services, ports, and protocols used that will need to be open in order for SSSD to be setup and used successfully….Network and Firewall Considerations –
| Service | Port | Protocol |
|---|---|---|
| DNS | 53 | UDP and TCP |
| LDAP | 389 | UDP and TCP |
| LDAP | 636 | UDP and TCP (optional if used) |
| Kerberos | 88 | UDP and TCP |
What is an IPA client?
FreeIPA is an open-source security solution for Linux which provides account management and centralized authentication, similar to Microsoft’s Active Directory. FreeIPA is built on top of multiple open source projects including the 389 Directory Server, MIT Kerberos, and SSSD.
Does FreeIPA provide similar services to Kerberos and if so what protocol is used?
FreeIPA uses standard components and protocols so any LDAP/Kerberos (and even NIS) client can interoperate with FreeIPA Directory Server for basic authentication and user/group enumeration. However additional management functionality can be achieved using the SSSD project.
Where is SSSD located?
SSSD services and domains are configured in a . conf file. By default, this is /etc/sssd/sssd.
How do I enable SSSD service?
There are two ways to change this behavior:
- Enabling SSSD through the authconfig command: ~]# authconfig –enablesssd –enablesssdauth –update.
- Adding the SSSD process to the start list using the chkconfig command: ~]# chkconfig sssd on.
What is SSSD configuration?
The [sssd] section contains configuration settings for SSSD monitor options, domains, and services. The SSSD monitor service manages the services that SSSD provides. The services entry defines the supported services, which should include nss for the Name Service Switch and pam for Pluggable Authentication Modules.
Is LDAPS a TLS?
LDAPS uses its own distinct network port to connect clients and servers. The default port for LDAP is port 389, but LDAPS uses port 636 and establishes TLS/SSL upon connecting with a client.
