[squid-users] Kerberos authentication problem - squid 3.4.11

[Markus Moeller]

It could be the new AD server  is setup to be backward  compatible meaning 
it use RC4 despite being able to use AES.  I suggest you crate an additional 
keytab entry for RC4.  How did you create the keytab ?

Hello,

the AD cluster is due to be upgraded. I think the old is 2003 and new is
2010(?). I am trying to authenticate against new one, I got the keytab
from it with the following:

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

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

I commented out allow_weak_crypto. The result is the same.
