Search responses with incorrect msgId

[Eduardo Ramos Testillano <eramos@tid.es>]

Hi all,

My application is an ldap client based on openLdap suite. I'm having 
problems when receiving search responses with incorrect msgId.
The problem is: always returns error -1 being impossible to discriminate 
other situations like remote server close.
The application always detach the connection fd when -1 is received (99% 
is broken connection).
But we don't want to do close this when "receive a search response with 
out-of-context msgId" (usually "out-of-time search result entries" after 
sending AbandonRequest from client).

I can't use ldap_msgid, because 'LDAPMessage*' is NULL and causes abort()
(anyway, no special result code is specified for this situation at 
ldap_msgid API description).

My code:
  LDAP* handle = (LDAP*) a_ldap;
  LDAPMessage* hmessage (NULL);
  resultCode = ldap_result (handle, LDAP_RES_ANY, LDAP_MSG_ONE, NULL, 
&hmessage);

// I test the following, hoping result is not -1 with 
LDAP_RES_UNSOLICITED, but it returned -1 again...
  if (resultCode.getValue () == -1)
     resultCode = ldap_result (handle, LDAP_RES_UNSOLICITED, 
LDAP_MSG_ONE, NULL, &hmessage);

¿do you know any other way to identify responses with incorrect msgid?

thnks
Regard,
Edu
