RE: (ITS#6828) TLS fails to start when LDAP_OPT_CONNECT_ASYNC is used
There is something missing from the fix. I just had a problem where an asynchronous connect was failing and the result was continuous looping with repeated calls to ldap_sasl_bind.
The problem is that if the connect fails, ldap_int_poll called from ldap_int_check_async_open gets an error and returns -1, and then -1 is returned up the stack ldap_int_check_async_open -> ldap_send_initial_request -> ldap_sasl_bind. But when ldap_sasl_bind gets that -1 return from ldap_send_initial_request it returns ld->ld_errno, and nowhere have we set that. In fact, ld->ld_errno still contains LDAP_X_CONNECTING from when the initial connect was issued, and so ldap_sasl_bind returns LDAP_X_CONNECTING, and that is what leads to the infinite looping that I see.
What is missing is that in ldap_int_check_async_open this:
Should be changed to:
ld->ld_errno = LDAP_CONNECT_ERROR;
