The Azure AD duration is set in seconds, while the AD duration is set in minutes.įor example, if you want your Azure AD smart lockout duration to be higher than AD DS, then Azure AD would be 120 seconds (2 minutes) while your on-premises AD is set to 1 minute (60 seconds).

The Azure AD lockout duration must be set longer than the AD DS reset account lockout counter after duration.

Set the values so that the AD DS account lockout threshold is at least two or three times greater than the Azure AD lockout threshold.

The Azure AD lockout threshold is less than the AD DS account lockout threshold.

When using pass-through authentication, the following considerations apply: By setting smart lockout policies in Azure AD appropriately, attacks can be filtered out before they reach on-premises AD DS.

Smart lockout can be integrated with hybrid deployments that use password hash sync or pass-through authentication to protect on-premises Active Directory Domain Services (AD DS) accounts from being locked out by attackers. Unfamiliar and familiar locations both have separate lockout counters. Smart Lockout uses familiar location vs unfamiliar location to differentiate between a bad actor and the genuine user.A user has ( threshold_limit * datacenter_count) number of attempts, if the user hits each data center. Each Azure AD data center tracks lockout independently.The lockout service attempts to ensure that bad actors can't gain access to a genuine user account. When smart lockout locks a user account, we try our best to not lock out the genuine user. Using smart lockout doesn't guarantee that a genuine user is never locked out. Customization of the smart lockout settings, with values specific to your organization, requires Azure AD Premium P1 or higher licenses for your users. Smart lockout is always on, for all Azure AD customers, with these default settings that offer the right mix of security and usability. Hash tracking functionality isn't available for customers with pass-through authentication enabled as authentication happens on-premises not in the cloud.įederated deployments that use AD FS 2016 and AF FS 2019 can enable similar benefits using AD FS Extranet Lockout and Extranet Smart Lockout. If someone enters the same bad password multiple times, this behavior won't cause the account to lock out. Smart lockout tracks the last three bad password hashes to avoid incrementing the lockout counter for the same password. To minimize the ways an attacker could work around this behavior, we don't disclose the rate at which the lockout period grows over additional unsuccessful sign-in attempts. The account locks again after each subsequent failed sign-in attempt, for one minute at first and longer in subsequent attempts.

How smart lockout worksīy default, smart lockout locks the account from sign-in attempts for one minute after 10 failed attempts for Azure Public and Azure China 21Vianet tenants and 3 for Azure US Government tenants. Attackers get locked out, while your users continue to access their accounts and be productive.

Smart lockout can recognize sign-ins that come from valid users and treat them differently than ones of attackers and other unknown sources. Smart lockout helps lock out bad actors that try to guess your users' passwords or use brute-force methods to get in.
