Can anyone tell me whether OpenLDAP has provisions for a client to
determine whether a connection has timed out proactively instead of
alerting a user that the connection has been closed due to timeout only
after they attempt an operation? If not then I'll know I will have to
roll my own method of keeping the connection alive through a periodic
query of some sort.
You might look at the persistent search function in my
Stanford::Directory perl module:
which tests to see if the connection has closed, and if it has,
reopens it, before performing a search.
Well I couldn't use the Perl module directly since my app is coded in
Java but looking at the script seems to suggest the ability to test for
an error code of -1 which would indicate the need for another connection
handle. If that is correct, then I am basically already doing that
because that method is still attempting a query and checking the return
code to determine if the query needs to be resent to the server.
Without performing some type of client-side polling using a query to
keep the connection open, there probably isn't any other way anyway.
