This is obviously is not what happens when you use Solaris adjoin.sh (adjoin-s10u5) or Samba's net ads join' command. Both of these approaches create a computer object specifically. The interesting behavior is adjoin.sh creates the computer object with one specific SPN (host/host.fqdn), where as Samba creates (HOST/HOSTNAME and HOST/host.fqdn). Solaris adjoin generates /etc/krb5/krb5.keytab with all the known authentications such as DES-CBC-MD5, DES-CBC-CRC and RC4-HMAC-MD5, where as the samba net ads keytab create simply doesn't create one. Mind you, I'm using Sun natively packaged Samba. Where as I can clearly see the UPN with adjoin.sh, the one I created with net ads doesn't. Both of them show the SamAccount as HOSTNAME$. The adjoin literally uses ldapadd to add the host to computers container.... Alright, I digress....back to Kerberos. I didnt get around the problem. So I'm going to install a Linux server and see how I fare. ________________________________________________ Kerberos mailing list [email protected] https://mailman.mit.edu/mailman/listinfo/kerberos
