The machine doesn't exist - an ip address that I can't ping.
I'm writing a QT-based LDAP browser and I want to make it user friendly.
Give the user an option of cancelling a request if they typed the wrong IP
address (for example)

How do I set the TIMEOUT values with set_option.
Could you give me an example of how to set OPT_TIMEOUT and
OPT_NETWORK_TIMEOUT to 10 secs??
I had thought from reading the python-ldap docs that simple_bind was an
asynchronous operation - that control would be returned to my program
immediately after issuing the request. However, on my machine, it blocks -
and then times out after around 90secs. Kind of annoying.
Is the synchronous/asynchronous nature of the call controlled in the
python-ldap module or is it a function of the OpenLDAP libs??

Yes, this seems to be OK. I get program control back immediately after the
ldap_open (ldap_initialie worked the same way).
Thanks for the response and many thanks for the work you've done on
python-ldap. You've helped make developing the app a much simpler task and
even kind of fun!!
Yours,
Jerry.
