Hello Henrique

 Actually I have the same problem as you. Firts I had tried an ADS w2k3 and Samba 3.0.2a integration without any success ( Only works IP NTML protocol, kerberos does not works ( hostaname instead IP address)) . After I tried w2k and Samba 3.0.2a integration and works fine. But I need an ADS w2k3 and Samba integration  and for the moment does not works. We need the Samba team help for solve this issue ASAP, Is it possible for us Samba Team?

Subject: [Samba] Samba 3.0.2a with ADS w2k3 Active Directory, enctypes

Hi people,

I have a Linux box running Samba 3.0.2a in ADS mode MIT Kerberos 1.3.3. My W2K e WXP users can't access the linux box by netbios name, the only access that works is by IP address, I know that's caused because access thought IP address don't make use of Kerberos. The most strange for me it's that the same environment works fine with a W2K Active Directory, I read in same list the problem was the kerberos 1.2.x, then I changed to 1.3.3, but the problem remains.
I also have tried the following combinations of parameters in the krb5.conf

Test 1 - No permitted_enctypes

[libdefaults]
	default_realm = HOME.EHC
# The following krb5.conf variables are only for MIT Kerberos.
	default_tgs_enctypes = des-cbc-crc des-cbc-md5
	default_tkt_enctypes = des-cbc-crc des-cbc-md5
	#permitted_enctypes = des-cbc-crc des-cbc-md5

Test 2 - all enctypes that I know

[libdefaults]
	default_realm = HOME.EHC
# The following krb5.conf variables are only for MIT Kerberos.
	default_tgs_enctypes = des-cbc-crc des-cbc-md5
	default_tkt_enctypes = des-cbc-crc des-cbc-md5
	permitted_enctypes = aes256-cts-hmac-sha1-96 aes128-cts-hmac-sha1-96 arcfour-hmac arcfour-hmac-exp arcfour-hmac-md5 des des-cbc-crc des-cbc-md4

Could anybody help me ? 
Does anybody have a list of MIT Kerberos 1.3.3 enctypes ?
Does anybody know what are the enctypes for Windows 2003 Active Directory ?
What does mean "...failed to decrypt with error Decrypt integrity check failed" in the enctype 3 ?

Thanks

Estevam Henrique
