This is a known bug (issue #1341) caused by an INNER JOIN in the GET_ALL_RESOURCE_TYPES SQL query. When a custom attribute is not restricted to specific resource types (i.e., no rows in custom_attribute_entities), the join filters out the values, so they appear blank after reload. As a temporary workaround, edit the attribute in Admin > Manage Attributes and assign it to all or specific resource types—this adds entries to custom_attribute_entities and makes values display. For a permanent fix, edit lib/Database/Commands/Queries.php: change the INNER JOIN with custom_attribute_entities to a LEFT JOIN in the query that builds attribute_list.

The API fails because PHP 8.3 emits an E_DEPRECATED notice (code 8192) from pear/net_ldap2, and Slim converts that notice into an exception. The web login does not use Slim's error handler, so it can still succeed. Preferred fix: update pear/net_ldap2 to a PHP 8.3-compatible release. If no update is available, patch vendor/pear/net_ldap2/Net/LDAP2/Search.php and add the compatibility attribute to the iterator method: #[\ReturnTypeWillChange] public function current() { ... }. Add the same attribute to key(), next(), rewind(), and valid() if similar deprecations appear. Because vendor/ is overwritten by Composer, maintain the patch with composer-patches or a private fork, then run composer update pear/net_ldap2 and restart PHP-FPM, for example: sudo systemctl restart php8.3-fpm. Temporary workaround: in plugins/Authentication/Ldap/Ldap2Wrapper.php, suppress E_DEPRECATED around the net_ldap2 code that triggers the error: $oldLevel = error_reporting(error_reporting() & ~E_DEPRECATED); try { class_exists('Net_LDAP2'); $ldap = Net_LDAP2::connect($config); // Keep the LDAP search/iteration inside this block if current() is triggered there } finally { error_reporting($oldLevel); }. As a last resort only, set error_reporting(E_ALL & ~E_DEPRECATED) before the Slim API handles requests; this hides all deprecation notices, not just the LDAP one.
