Re: (ITS#4494) connections are not asynchrounous

Your efforts are appreciated.

Please see my additional responses inline below.

My single-threaded application requires that multiple connection
attempts may be in-progress simultaneously, in conjunction with other
activities that need timely attention.  In other words, I need to have
multiple connections in non-blocking SSL_connect() at the same time,
with the application doing select() on all the LDAP connection sockets
as needed.  The fix you have provided will allow this?

What is the time-frame for this to be available in a "stable" version?

That's all for now,

I could try using ldap_start_tls() as a quick-and-dirty test to verify
that you have fixed the connection issues, but it is not acceptable for
our production use.  We must support LDAPv2, which does not allow the
use of start TLS.

Are you planning to support this for ldaps: URLs in the future?

Do you need/want me to verify that using start TLS with your patches
fixes the connection issues?  I would prefer to hold off until the
ldaps: support is in place.

What is the "right HEAD" CVS branch?  Do I have access to that branch
via anonymous CVS?  I am not very familiar with CVS, a sample command
line to retrieve the correct sources would be quite helpful.

Can I leave LDAP_OPT_CONNECT_ASYNC set to TRUE always?  I would like
referrals, if used, to be non-blocking as well.

Could you make this automatic in ldap_int_tls_start()?
