[Samba] Must I remove gnome-kerberos-0.3.1-9?

[maorui]

  I managed to setup samba3.0 as a win2k domain member, and modified smb.conf & krb5.conf.
  But when I try kinit administrator at domain, I got an error.

--> kinit(v5):KDC has no support for encryption type while getting initial credentials

  I found gnome-kerberos-0.3.1-9 was shipped with RH9. Did it support all kerberos function Samba3 need?
  Must I remove it and install MIT or Heimdal Kerberos package?
