Referrals point directory clients to another directory server. The client receiving a referral must then connect to the other server to complete the request. Referrals are used for example when a directory server is temporarily unavailable for maintenance. Referrals can also be used when a server contains only some of the directory data for a suffix and points to other servers for branches whose data is not available locally. This chapter demonstrates how to set up referrals, and how to follow them with the command-line tools.
