Feature/Application:

SonicWall Directory Services Connector provides an option for the SSO Agent to identify logged in user information from the Domain Controller's Windows Security Log (DC Security Log or WSL). When using DC Security Log mode, Directory Services Connector fetches security logs from the configured Domain Controller. It uses SonicWall SSO UDP Protocol version 4.0.

The DC Security Log method works in a fully trusted domain environment where all users are domain users using domain accounts to access Windows or Linux workstations.

The DC Security Log method can optionally be used with either NETAPI or WMI as a fall back to support user identification from non-domain Windows PCs or Domain PCs using local accounts. Altogether, there are three Query Source options involving the DC Security Log:

DC Security Log Users will be identified from the Domain Controller's Windows Security Log; use this option if all users log into the domain.
DC Security Log + NETAPI In addition to using the DC Security Log, this option provides a fall back to using NETAPI to identify users. In case the SSO agent fails to identify users from the Domain Controller, it uses traditional NETAPI queries to the user's workstation to fetch user information.
DC Security Log + WMI In addition to using the DC Security Log, this option provides a fall back to using WMI to identify users. In case the SSO agent fails to identify users from the Domain Controller, it uses traditional WMI queries to the user's workstation to fetch user information.

To use DC Security Log mode in SonicWall Directory Services Connector, ensure that the Agent machine has the following minimum requirements:

Multi-Core processors: 2 or more, or a dual CPU
Speed: 2GHz+
RAM: 2GB, minimum

Note: For single core processors, CPU spikes may reach up to 100% periodically while using DC Security Log mode in SonicWall Directory Services Connector. To avoid this, optimization is provided for reading security logs. Also an option is available to read the security logs in current time, minimizing the initial log processing time.

By default, all of the DC Security Log options require a Domain Administrator account or Local Administrator account on the Domain Controller to read the DC Security Log. The account information is entered during the configuration, described below. If an account with administrator privileges is not available, user identification via the Domain Controller Security Log can be configured for WMI with a non-administrator domain account.

User identification via the Domain Controller Security Log can also be configured by using WMI with a Non-Administrator domain account. Although this option does not require use of the administrator domain account,it still requires read access to the security log, which can be accomplished by configuring a non-admin account.
