Choosing SSSD or Winbind & Samba for Active Directory Integration in CentOS/RHEL

By admin

Question: Should I use SSSD, or Samba and Winbind to integrate my Oracle Linux system with Active Directory?

All supported versions of Oracle Linux provide both SSSD and Samba with Winbind.

SSSD:

  • does not support NTLM, but NTLM is insecure and obsolete
  • is simpler to install (can be auto-configured using realmd)
  • does more than just Active Directory (e.g. LDAP)

Samba/Winbind:

  • is harder to secure due to its support for NTLM.
  • does not support AD DNS Aging and Scavenging (i.e. detecting if DNS entries for servers that have been removed or updated)
  • As of Oracle Linux 7, SSSD is the preferred tool, although Samba and Winbind remain fully supported.

Using SSSD for Active Directory is covered here:
