Kerberos Authentication Error

Jeff Carlin — Thu, 24 Feb 2005 14:31:44 GMT

I am having some trouble with new installation of Kerberos v5 client. I'm just learning... After successfully validating against a MS 2003 AD server, subsuquent commands like FTP back to myself fail. I assume a good test to see if my credentials are being passed for SSO is telneting or FTPing back to my self...?

When I sign on, I get the proper kerberos password prompt and when I enter the password that is in AD I am allowed to sign on. I know this is correct, since my local password on the HP is different. If I klist, I see a new ticket. If I telnet back to the same host, I get the following:

------------------------------------------
$ telnet ptwlab13
Trying...
Connected to ptwlab13.kih.kmarttest.com.
Escape character is '^]'.
ERROR! Kerberos authentication failed.
To bypass Kerberos authentication, use the -P option.
Local flow control on
Connection closed by foreign host.
$
------------------------------------------

Likewise, if I ftp it fails, but there is more information I think:

------------------------------------------
$ ftp ptwlab13
Connected to ptwlab13.kih.kmarttest.com.
220 ptwlab13.kih.kmarttest.com FTP server (Version 1.1.214.4(PHNE_30990) Mon Nov 15 12:47:12 GMT 2004) ready.
Error initializing security using principal 'ftp@ptwlab13.kih.kmarttest.com':
Miscellaneous failure
Server not found in Kerberos database
Error initializing security using principal 'host@ptwlab13.kih.kmarttest.com':
Miscellaneous failure
KRB5 error code 52
ERROR! Kerberos authentication failed.
ftp>
--------------------------------------------

I'm using the newer krb5client software from HP that is supposed to use tcp. Anyone able to help me along here?

This thread appears to have the same error code:

Perhaps there is a solution in there.

There is a way to build kerebos into your ftp authentication. I recall this from an Internet Security Class.

Are doing that? You may need to to make ftp work under these circumstances.
