<< GNU/Linux Distributions >>

If you are newly introduced to the world of Linux, soon you will notice that it has mutiple faces or distributions. Once you know how distributions differ from each other then it can help you a lot in building your Linux experience. However, not every distributions are meant to be used by everyone hence it is important to select or indentify the right distro and at the same time nothing wrong to try out any distributions.

 CentOS Linux is a community-supported distribution derived from sources freely provided to the public by Red Hat for Red Hat Enterprise Linux (RHEL). As such, CentOS Linux aims to be functionally compatible with RHEL. The CentOS Project mainly change packages to remove upstream vendor branding and artwork. CentOS Linux is no-cost and free to redistribute. Each CentOS version is maintained for up to 10 years (by means of security updates — the duration of the support interval by Red Hat has varied over time with respect to Sources released). A new CentOS version is released approximately every 2 years and each CentOS version is periodically updated (roughly every 6 months) to support newer hardware. This results in a secure, low-maintenance, reliable, predictable and reproducible Linux environment.

 Many IT environments are heterogeneous. In a mixed environment, there has to be some way to join systems to a single domain or a forest, either directly as clients or by creating separate domains or forests connected to each other. Red Hat Enterprise Linux  can help a Linux system or an entire Linux forest integrate with an Active Directory environment.

The System Security Services Daemon (SSSD) provides access to different identity and authentication providers. This service ties a local system to a larger back end system. That can be a simple LDAP directory, domains for Active Directory or IdM in Red Hat Enterprise Linux, or Kerberos realms.

realmd to connects to an Active Directory Domain. realmd simplifies the configuration. realmd can run a service discovery to identify different, available domains ( both Active Directory and Red Hat Enterprise Linux Identity Management ), and then join the domain and manage user access. realmd can discover and support multiple domains because the underlying service (SSSD) supports multiple domains.
