problem with ldap_search _ext and ldap_result

After binding the ldap server, here are my code snippets,

finished = 0;

rc = ldap_search_ext( ld, "testactivedirectory.com", sub_tree, "(sAMAccountName=user1)", NULL, 0, NULL, NULL, NULL, 1, &msgid );

if ( rc != LDAP_SUCCESS ) { fprintf( stderr, "ldap_search_ext: %s \n", ldap_err2string( rc ) ); ldap_unbind( ld ); return( 1 ); } while (!finished) { rc = ldap_result( ld, msgid, LDAP_MSG_ONE, &zerotime, &res ); printf("check the search result :%d\n", rc);

switch ( rc ) { case -1: fprintf( stderr, "ldap_result: %s\n", ldap_err2string( rc ) ); ldap_unbind( ld ); return( 1 );

case 0: break;

case LDAP_RES_SEARCH_ENTRY: /* Get and print the DN of the entry. */ if (( dn = ldap_get_dn( ld, res )) != NULL ) { printf( "dn-> %s\n", dn ); ldap_memfree( dn ); } break; case LDAP_RES_SEARCH_RESULT: finished = 1; break; default: break;

} }

while running this program, i could get the intended result what the distinguished name i want, but the ldap_result in not being exit with LDAP_RES_SEARCH_RESULT option. it tooks lot of time to respond with LDAP_RES_SEARCH_RESULT, even no more entry to provide.

check the search result :100 dn-> CN=user1,CN=Users,DC=testactivedirectory,DC=com (it waits in looop... it exits after a very long time) check the search result :101

i wanted to avoid this waiting time, even i have been sending entries should be limited to 1, it doesn't seems to be reflected, i have found other way of fixing this, doing two bind and two unbind option. but that is not seems a optimized manner.

Let me know how to fix this problem,

Thanks, LDAP Learner
