[Samba] Re: bad encryption type when accessing AD member server

So understanding that, I get this error,

[2003/10/02 17:10:23, 3] libads/kerberos_verify.c:ads_verify_ticket(310)
  ads_verify_ticket: enc type [23] failed to decrypt with error Decrypt
integrity check failed

Any suggestions to where to look to find this one? Could it be something
with the Win2k3 server?

[derek@atlantis samba]# klist -e
Ticket cache: FILE:/tmp/krb5cc_0
Default principal: derek@PC.CS.UMD.EDU

Valid starting     Expires            Service principal
10/02/03 17:06:16  10/03/03 03:06:20  krbtgt/PC.CS.UMD.EDU@PC.CS.UMD.EDU
        renew until 10/02/03 18:06:16, Etype (skey, tkt): ArcFour with
HMAC/md5, ArcFour with HMAC/md5


Kerberos 4 ticket cache: /tmp/tkt0
klist: You have no tickets cached

So I am getting ArcFour tickets by default here.
