    Pass client flag to KDB for client preauth match
    
    In the kdcpreauth match_client() callback, if it is necessary to look
    up the given principal in the KDB, pass KRB5_KDB_FLAG_CLIENT to
    krb5_db_get_principal().  Samba requires this flag to properly handle
    enterprise client principals.
