[squid-users] Kerberos authentication problem - squid 3.4.11

[Markus Moeller]

Hi Ludovit,

  Which Kerberos library version do you use ?    Is it possible that the 
encryption types don't match ?  I saw in your first email the following:

Your klist shows a HTTP ticket for arcfour

Server: HTTP/squid1.mdpt.local at MDPT.LOCAL
Client: HTTP/squid1.mdpt.local at MDPT.LOCAL
Ticket etype: arcfour-hmac-md5, kvno 8
Ticket length: 1090
Auth time:  Feb  9 14:55:18 2015
Start time: Feb  9 14:55:20 2015
End time:   Feb 10 00:55:18 2015
Ticket flags: enc-pa-rep, pre-authent
Addresses: addressless

but the keytab has aes128.

# ktutil -k /etc/krb5.keytab list
/etc/krb5.keytab:

Vno  Type                     Principal                          Aliases
  8  aes128-cts-hmac-sha1-96  HTTP/squid1.mdpt.local at MDPT.LOCAL

Hello,
