question about the ldap client program..

["Wu, Chia-Jen" <chiajen@mitt.com.tw>]

Hi, all
  I execute the client programs that locates in ldap/client/tools/*.c 
  and have questions about these programs (I run them under Win95):
  1) I issue the command:
     %ldapmodify.exe -h 203.67.126.181 -f d:/Modify.wu
     where the Modify.wu is:
        dn: cn=maison, ou=g2, o=mitt, c=tw  
        changetype: add
        cn: Maison
        cn: chi-wen
        sn: Cheng
        objectclass: person
        telephoneNumber: 2755-6183-39
     But it seems that not truly add in my ldap server, why?
     The return code is 34, which means unavailable. What is it?
     Do I miss s.t.?
  2) In ldapsearch.c, the return of line 386(ldap_get_dn) and 
     line 393(ldap_dn2ufn) seems not save. They will halt on the 
     free() operation. Do their spaces really allocated by malloc()? 

thank you in advance
with best regards
