 Hi
 Trying to use 
   eudc-query-form 
 and entering a search for a name gives: 
 Signaling: (wrong-type-argument char-or-string-p nil)
  [...] 
I suspect something weird with the way binary values in that record are handled
but I am not sure.  Would it be feasible to try the same query on XEmacs 21.2 ?
Also, could you try to evaluate the following in XEmacs 21.1:
(ldap-search "(cn=vzell)" "ldap01.us.oracle.com")

PS: You're using XEmacs native LDAP support, not the FSF Emacs emulation
    relying on the external ldapsearch utility, right ?
