Re: ldap_simple_bind blocks in Open Mode when the DS is in hang state

denish, please keep this thread on the list. neither network or
connect timeout would apply in this case as i have explained in
my previous message. you can specify timeout for ldap_result()
call which is where it blocks in this case. again, this timeout
has nothing to do with network stack timeouts but simply a time
out for response on specific LDAP operation/s result/s.
