Re: query timeout and proxytemplate

Wonderful help.  It showed that I wasn't indexing the attribute I was
querying.  That is done and now the debug level responds with QUERY
ANSWERABLE.  Looks like the proxy is actually working.  

Well, almost.  If the master server is there, it returns with the answer and
all looks good.  If the master server isn't there for the proxy, the proxy
still responds in debug with QUERY ANSWERABLE, but blocks after that.  This
causes ldapsearch to stay blocked as well.  

Why would a proxy still check with the master If the proxy is working?  I
want to use this to relieve processing from the master.  

It also gets back to the other part of my problem.  Since it seems to block
indefinitely, how can I set a decent timeout for slapd?  

Again, thanks for the help so far.

In order to test the proxy caching function run your proxy slapd with
-d pcache.
