How failover and disconnected access work
The Centrify agent caches data from Active Directory so that users can log on and perform tasks even if the network or Active Directory server is unavailable, whether because of unexpected connectivity problems, scheduled maintenance, or offline operation of a portable computer. There are several configuration parameters that manage how the agent determines its connectivity to Active Directory, the domain controllers it should attempt to connect to, and the operation of the agent if it is unable to connect to any domain controller.
In most cases, you can set the values for the configuration parameters that control failover and disconnected operation by enabling Centrify group policies for a site, domain, or organizational unit. Alternatively, you can set these parameters by editing the /etc/centrifydc/centrifydc.conf configuration file on individual computers.
