Thank you for reporting this. The issue has been solved. See also bug ~~#15178~~ in the LDAP queue. Please upgrade to https://packagist.org/packages/horde/ldap#v3.0.0alpha8

Replacing the is_resource() calls with is_object() calls in vendor/horde/ldap/lib/Horde/Ldap/Entry.php gets LDAP authentication working under PHP 8.2 for me.

After doing some searching on the exact error message, I found a forum thread for a different application where this error message started showing up after upgrading from PHP 8.0 to a higher version. For testing purposes, I installed the required PHP 8.0.30 packages from the Remi-Safe repository and reconfigured the Apache virtualhost to use PHP 8.0 rather than PHP 8.2. LDAP logins immediately started working. This appears to be a PHP 8.1+ issue; from the PHP documentation at https://www.php.net/manual/en/migration81.incompatible.php: * The LDAP functions now accept and return LDAP\Connection objects instead of ldap link resources. * The LDAP functions now accept and return LDAP\Result objects instead of ldap result resources. * The LDAP functions now accept and return LDAP\ResultEntry objects instead of ldap result entry resources.

After configuring LDAP authentication and attempting to log in, the following error message is produced (browser and syslog): HORDE[1570]:[horde] Unable to create connected entry: Parameter $entry needs to be a ldap entry resource! [pid 1570 on line 186 of"/var/www/html/horde6/vendor/horde/ldap/lib/Horde/Ldap/Entry.php"] PHP version is 8.2.12.
