LoginLDAP not working after Update to 4.3.1


after upgrading to Matomo 4.5 and LoginLDAP plugin 4.3.1 we are not able to synchronize users on CMD, the following error message is displayed:

WARNING [2021-12-10 09:38:12] 101719 /srv/www/htdocs/matomo/vendor/matomo/doctrine-cache-fork/lib/Doctrine/Common/Cache/FileCache.php(250): Notice - tempnam(): file created in the system’s temporary directory - Matomo 4.5.0

A sync in the GUI works, login also works.

Does anyone know a solution?
