Active Directory Site Support

Before you install UNAB, you should understand how UNAB implements Active Directory site support. Active Directory site support helps to optimize network traffic, increase connection speed, and decrease response time.

When you register a UNAB endpoint with Active Directory, by default the uxconsole utility does the following:

• Discovers the Active Directory site that is closest to the physical location of the endpoint.
• Writes the name of the Active Directory site to the ad_site configuration setting in the ad section of the uxauth.ini file.

After registration, the UNAB endpoint communicates only with the domain controllers (DCs) in the discovered Active Directory site. If the endpoint cannot communicate with a DC in this site, the status of the UNAB endpoint changes to offline.

We recommend that you do not change the default behavior. However, when you customize the UNAB installation package, you can specify a list of DCs that the UNAB endpoint communicates with and a list of DCs that the UNAB endpoint ignores (the lookup_dc_list and the ignore_dc_list parameters, respectively). The DCs that you specify in these lists interact with Active Directory site support in the following ways:

• lookup_dc_list—The UNAB endpoint communicates with the DCs listed in this configuration setting, and does not communicate with the DCs discovered by Active Directory site support or DNS query.
• ignore_dc_list—The UNAB endpoint communicates with any DC discovered by Active Directory site support or DNS query that is not listed in this configuration setting.

Note: After installation, you can use the uxconsole -register utility to manually set the Active Directory site with which the UNAB endpoint communicates. For more information about the uxconsole utility, see the Reference Guide.
