Re: [squid-users] squid_kerb_auth.... Key Version number?

Hi again,

now I created the HTTP.keytab file on Win2k8 server and actually
the apps "klist -ke" and kvno say the key versions are VALID.

but squid is of the opion that they differ.

# klist -ke
Keytab name: FILE:/etc/squid/HTTP.keytab
KVNO Principal
----
--------------------------------------------------------------------------
   5 HTTP/fqdn_at_DOMAIN (DES cbc mode with CRC-32)
   5 HTTP/fqdn_at_DOMAIN (DES cbc mode with RSA-MD5)
   5 HTTP/fqdn_at_DOMAIN (ArcFour with HMAC/md5)
   5 HTTP/fqdn_at_DOMAIN (AES-256 CTS mode with 96-bit SHA-1 HMAC)
   5 HTTP/fqdn_at_DOMAIN (AES-128 CTS mode with 96-bit SHA-1 HMAC)

# kvno -k /etc/squid/HTTP.keytab HTTP/fqdn_at_DOMAIN
HTTP/fqdn_at_DOMAIN: kvno = 5, keytab entry valid

From where does squid get his wrong impression?

My squid.conf
auth_param negotiate program squid_kerb_auth -d -s HTTP/fqdn_at_DOMAIN

Maybe I can support anyone by my detailed described errors. :-)

Regards
Andrew
