Steps to reproduce:

1. Install Zabbix 8.0.0 on Rocky Linux 9.
2. Configure an LDAP connection in Zabbix.
3. Create a user group named "Zabbix Administrator (LDAP)".
4. Set the group's authentication source to the previously configured LDAP connection.
5. Navigate to Users → Users.
6. Click on Create user.
7. Fill in the required user details (username, name, surname, etc.).
8. Assign the new user to the "Zabbix Administrator (LDAP)" group.
9. Try to save the new user without entering a local password.

Result:

Zabbix prevents the user from being created and displays a validation error in the browser's JavaScript console:
text{{Validation error for missing field "/password1": This field cannot be empty.
Validation error for missing field "/password2": This field cannot be empty.}}
The password fields are not displayed in the user creation form, but Zabbix still validates them as mandatory.

Expected:

Zabbix should allow the creation of users assigned to an LDAP authentication group without requiring a local password.

Since these users authenticate against the configured LDAP server, a local Zabbix password should not be required.

The user should be created successfully using the LDAP authentication configuration.
