TypeError | Library/Configuration.php::getLdapAttributes, line 378: str_ends_with(): Argument #1 ($haystack) must be of type string, int given

Hey,

I just got this exception after an update from 3.7 to 4.0.2, and PHP from 7.4 to 8.2.

The method parameter is an associative array for simple field mappings: ['title' => '<dn>'].
With my hook mapping department = {hookName|department} the param is a flat array: ['{hookName|department}']

This check fails, since $field is an index:

foreach ($mapping as $field => $attribute) {
    if (str_ends_with($field, '.')) {
    ...

I checked the docs reagrding hooks, but looks like nothing has changed.

A quick fix in my case was changing this call

t3ext-ig_ldap_sso_auth/Classes/Library/Authentication.php

Line 820 in 10429e2

$ldapAttributes = Configuration::getLdapAttributes([$value]);

to $ldapAttributes = Configuration::getLdapAttributes([$field => $value]);

We have quite a simple setup, I didn't really test much further, but seems to work in my case.

Same here.
My quick fix was cast the $field variable to a string to ensure compatibility with str_ends_with.
This avoids potential type errors and allows the condition to work as intended.

if (str_ends_with((string)$field, '.')) { // This is a TypoScript configuration continue; }

Casting to string sounds good. mind opening a PR?
