mixed case hostname issue

[Matt Zagrabelny]

Greetings,

I have a mixed-case hostname:

kplz354S2 (note the capital 'S'), its FQDN is kplz354S2.d.umn.edu.

When I try to telnet to it:

% telnet kplz354S2.d.umn.edu
Trying 10.25.1.14...
Will send login name and/or authentication information.
Connected to kplz354S2.d.umn.edu (10.25.1.14).
Escape character is '^]'.
[ Kerberos V5 refuses authentication ]
kerberos_server_auth:   Couldn't authenticate client from
grateful.d.umn.edu.

% Authentication failed

% Authentication failed
Connection closed by foreign host.



I get the following message in my kdc.log:

Mar 31 10:05:50 stout krb5kdc[27785](info): TGS_REQ (1 etypes {1})
131.212.60.196: UNKNOWN_SERVER: authtime 1270046583,  mzagrabe at D.UMN.EDU
for host/kplz354s2.d.umn.edu at D.UMN.EDU, Server not found in Kerberos
database

Note the lower-case 's' in the FQDN.

The principal in the KDC database matches the mixed-case FQDN:

kadmin.local:  listprincs
<snip>
host/kplz354S2.d.umn.edu at D.UMN.EDU
<snip>


FWIW, I've grepped /usr/share/doc/krb* for the word 'case' and didn't
find any hits.

Any ideas on this one?

Thanks,
