[Samba] kerberos_kinit_password host/SUNDEV@LEXI.COM.MX failed: Client not found in Kerberos database

[P V]

   I'm using Solaris 8, samba 3, kerberos and
openldap. I'm anexing: log.smbd, smb.conf, krb5.conf,
nsswitch.conf and the ktpass command in AD.
   Somebody can help me? 

   I get this output in log.smbd:

   I've configured smb.conf with this data:

    workgroup = LEXI2K
    netbios name = SUNDEV

    # winbindd configuration
    # default winbind separator is \, which is good if
you
    # use mod_ntlm since that is the character it
uses.
    # users only need to know the one syntax
    # winbind separator = +

    # idmap uid and idmap gid are aliases for
    # winbind uid and winbid gid, respectively
    idmap uid = 10000-20000
    idmap gid = 10000-20000
    winbind enum users = yes

    #
    # Note that more recent Samba versions have
renamed "ads server"
    # to "password server", so if /var/log/messages
reports
    # 'Unknown parameter encountered: "ads server"' on
restart,
    # change 'ads' to 'password' -- ChetHosey
    #
    # ads server = test1.thinclient.test.org

   The nsswitch.conf is this:
---------------
passwd:     files winbind
group:      files winbind
hosts:      files wins
shadow:     files winbind

    The instruction in the ActiveDirectory Domain
Controller was:
  C:\temp>ktpass -princ
host/sundev.flexi.com.mx at FLEXI.COM.MX -mapuser SUNDEV
-pass password -out sundev.keytab
