5. SSSD and Active Directory
This section describes the use of sssd to authenticate user logins against an Active Directory via using sssd's "ad" provider. In previous versions of sssd, it was possible to authenticate using the "ldap" provider. However, when authenticating against a Microsoft Windows AD Domain Controller, it was generally necessary to install the POSIX AD extensions on the Domain Controller. The "ad" provider simplifies the configuration and requires no modifications to the AD structure.
