[Samba] kerberos auth fails in samba3.0 alpha23

[more]

Hi, I think I should append this information:

I use "net ads join" to join my computer to win2k AD domain, the system 
prompt to let me input root password. But I have maken a Administrator 
key in win2k AD domain in my Linux box.
It is not useful to input a password for there is not "root" account in 
the win2k AD domain at all. "net ads join" outputs as blow:

root password:
[2003/04/16 13:21:04, 1] libsmb/clikrb5.c:krb5_mk_req2(266)
  krb5_cc_get_principal failed (No credentials cache file found)
[2003/04/16 13:21:04, 0] libads/kerberos.c:ads_kinit_password(132)
  kerberos_kinit_password root at RAIDTEC.CHINA failed: Client not found in 
Kerberos database
[2003/04/16 13:21:04, 1] utils/net_ads.c:ads_startup(160)
  ads_connect: Invalid credentials

I just puzzled why samba asks for root account now, any help will be 
great thanks.
