OpenDirectory Authentication fails

Users mailing list
    We have freeradius with the open directory plugin, which accesses a mac server to authenticate users. This works for most users, but we have a few users that experience errors what I cannot understand.
     
    In the inner tunnel the OpenDirectory plugin accesses the server and when it fails it logs a weird value for shortUserName (HWeissbrodt7.0.0A?؎???). For the users which can use the radius server username_string and shortUserName are the same.
     
    I traced the debug print to https://github.com/ether42/freeradius-ldap-kerberos/blob/master/radius/freeradius-server-3.1.0/src/modules/rlm_mschap/opendir.c#L153 which suggests — for me — that it is a problem with the open directory communication, but I am neither sure nor can I see how the shortUserName can become that strange in the first place.
     
    I attached the radiusd -X output and the ldapsearch result.
     
    Snippet to highlight the error:

  The shortUserName comes from OpenDirectory.  i.e. FreeRADIUS asks OpenDirectory for the short name, and that's what OD returns.

  Huh?  There *is* an official FreeRADIUS repository:  https://github.com/FreeRADIUS/freeradius-server/

  I don't know.  If that's what comes back from OpenDirectory, there isn't much that FreeRADIUS can do about it.
