如何使用jldap库来解析openldap中Kerberos的'krbprincipalkey‘属性？

import com.novell.ldap.*;
import java.util.Base64;

public class LDAPExample {
    public static void main(String[] args) {
        String ldapHost = "ldap.example.com";
        int ldapPort = 389;
        String ldapAdminDN = "cn=admin,dc=example,dc=com";
        String ldapAdminPassword = "adminPassword";
        String searchBaseDN = "ou=users,dc=example,dc=com";
        String searchFilter = "(krbprincipalkey=*)";

        try {
            LDAPConnection ldapConnection = new LDAPConnection();
            ldapConnection.connect(ldapHost, ldapPort);
            ldapConnection.bind(LDAPConnection.LDAP_V3, ldapAdminDN, ldapAdminPassword.getBytes());

            LDAPSearchResults searchResults = ldapConnection.search(searchBaseDN, LDAPConnection.SCOPE_SUB, searchFilter, null, false);

            while (searchResults.hasMore()) {
                LDAPEntry entry = searchResults.next();
                LDAPAttribute attribute = entry.getAttribute("krbprincipalkey");

                if (attribute != null) {
                    LDAPAttributeEnumeration values = attribute.getAttributeValues();
                    while (values.hasMore()) {
                        String krbPrincipalKey = values.next().getStringValue();
                        // 解析和处理krbPrincipalKey属性的值
                        byte[] decodedKey = Base64.getDecoder().decode(krbPrincipalKey);
                        // 其他处理...
                    }
                }
            }

            ldapConnection.disconnect();
        } catch (LDAPException e) {
            e.printStackTrace();
        }
    }
}
