identd giving failures

[Alan Chandler <alan@chandlerfamily.org.uk>]

I am trying to set up postgres to dump across the network, using ident 
checking on the username of the caller.

But it always failing.  When I turn on logging of requests by identd, I find 
the following in the log

Aug 28 23:50:41 kanger identd[18705]: netlink_lookup: write failed: Connection 
refused
Aug 28 23:50:41 kanger identd[18705]: reply to 192.168.0.20: 41660 , 5432 : 
ERROR: UNKNOWN-ERROR

Aug 28 23:50:41 kanger identd[18705]: reply to 192.168.0.20: 41661 , 5432 : 
ERROR: UNKNOWN-ERROR


Has anyone seen these sort of errors before and what is causing them?
