The most risky bug in this code is:
Improper handling of potential null values for critical methods, specifically in the getLdapGroupDn() method being able to return null, which can lead to a NullPointerException.

You can modify the code like this:

public List<String> getLdapGroupDn() {
    if (properties.get(LDAP_GROUP_DN) == null) {
        // Return an empty list instead of null to avoid NullPointerException
        return List.of();
    } else {
        return List.of(properties.get(LDAP_GROUP_DN).split(";\\s*"));
    }
}
