PHP Warning in backend regarding IconFactory.php when using PHP 8

[Dominik]

Hi,

In the TYPO3 backend list module I get the following message for every user or group element:

PHP Warning
Core: Error handler (BE): PHP Warning: Undefined array key "disable" in /var/www/html/typo3conf/ext/ig_ldap_sso_auth/Classes/Hooks/IconFactory.php line 48

Regards,
Dominik
