+Server location interface (locate)
+==================================
+
+The locate interface allows modules to control how KDCs and similar
+services are located by clients.  For a detailed description of the
+ccselect interface, see the header file ``<krb5/locate_plugin.h>``.
+
+.. note: The locate interface does not follow the normal conventions
+         for MIT krb5 pluggable interfaces, because it was made public
+         before those conventions were established.
+
+A locate module exports a structure object of type
+krb5plugin_service_locate_ftable, with the name ``service_locator``.
+The structure contains a minor version and pointers to the module's
+methods.
+
+The primary locate method is **lookup**, which accepts a service type,
+realm name, desired socket type, and desired address family (which
+will be AF_UNSPEC if no specific address family is desired).  The
+method should invoke the callback function once for each server
+address it wants to return, passing a socket type (SOCK_STREAM for TCP
+or SOCK_DGRAM for UDP) and socket address.  The **lookup** method
+should return 0 if it has authoritatively determined the server
+addresses for the realm, KRB5_PLUGIN_NO_HANDLE if it wants to let
+other location mechanisms determine the server addresses, or another
+code if it experienced a failure which should abort the location
+process.
+
+A module can create and destroy per-library-context state objects by
+implementing the **init** and **fini** methods.  State objects have
+the type void \*, and should be cast to an internal type for the state
+object.
