Authentication

Hello again.
Something strange is happening.
I implemented the changes you described. And found that for some reason the scritp does not reach the for statement in line 238.
With some more investigation, I found that it jumps out of scope in the if clause on line 232.
Here are the debug lines I added:

// If at least one field is mapped from external db, get that mapped data.
if ($selectfields) {
$select = array();
$fieldcount = 0;
foreach ($selectfields as $localname=>$externalname) {
// Without aliasing, multiple occurrences of the same external
// name can coalesce in only occurrence in the result.
$select[] = "$externalname AS F".$fieldcount;
$fieldcount++;
}
$select = implode(', ', $select);
$sql = "SELECT $select
FROM {$this->config->table}
WHERE {$this->config->fielduser} = '".$this->ext_addslashes($extusername)."'";
// HMP
mtrace("DEBUG-3: Select Columns == $select");
mtrace("DEBUG-4: Sql Query = $sql");
if ($rs = $authdb->Execute($sql)) {
mtrace("DEBUG-5: RecordSet == $rs");
if (!$rs->EOF) {
mtrace("DEBUG-6: ");
$fields = $rs->FetchRow();
// Convert the associative array to an array of its values so we don't have to worry about the case of its keys.
$fields = array_values($fields);
foreach (array_keys($selectfields) as $index => $localname) {
$value = $fields[$index];
// HMP
mtrace("DEBUG-1: $localname == $value");
$result[$localname] = core_text::convert($value, $this->config->extencoding, 'utf-8');
}
}
$rs->Close();

And here is the result from running the script on command line:
--------------------------------
DEBUG-3: Select Columns == FIRSTNAME AS F0, LASTNAME AS F1, EMAIL AS F2, INSTITUTION AS F3, PROFILE_FIELD_ENTIDADE AS F4, USERNAME AS F5

Has it can be seen, I do not reach DEBUG-1 which is your statement, nor do I get to DEBUG-6 that I added, but I do get DEBUG-5.
Between DEBUG-5 and DEBUG-6 is the if clause. Something is wrong in that recordset, the if clause is to test EOF in the recordset, but apparently from DEBUG-5 there is data on the recordset...
Maybe something wrong from using Oracle DB?
