EXTENDED DESCRIPTION

24       arc-infoindex-relay  acts  as a bridge between the slapd server and the
25       arc-infoindex-server in the NorduGrid ARC Information system. For  each
26       index  served  by  the  arc-infoindex-server  a  shell backend database
27       should be configured in the slapd configuration.
28
29       Here is a sample configuration:
30
31       database  shell
32       suffix    "Mds-Vo-name=Sweden,o=Grid"
33       bind      /usr/sbin/arc-infoindex-relay /var/run/arc/infosys/giis-fifo
34       add       /usr/sbin/arc-infoindex-relay /var/run/arc/infosys/giis-fifo
35       search    /usr/sbin/arc-infoindex-relay /var/run/arc/infosys/giis-fifo
36       access to * by * write
37
38       When a query for the configured  database  is  recieved  by  the  slapd
39       server,  the  server will call out to the arc-infoindex-relay. The arc-
40       infoindex-relay will then open a unique return FIFO for this query  and
41       then  forward  the  query  and  the name of the return FIFO to the arc-
42       infoindex-server through the configured  server  FIFO.  When  the  arc-
43       infoindex-server  has  processed the query it will return the result to
44       the arc-infoindex-relay using the return FIFO. The  arc-infoindex-relay
45       then  closes  the  return  FIFO  and forwards the response to the slapd
46       server.
