Following is my krb5.conf details,
I tried both msktutil and ktpass in the active directory domain
server. The thing is working well with NTLM.

krb5.conf
=======
[logging]
 default = FILE:/var/log/krb5libs.log
 kdc = FILE:/var/log/krb5kdc.log
 admin_server = FILE:/var/log/kadmind.log

[libdefaults]
 default_realm = ACCT.SYSNET.LOCAL
 dns_lookup_realm = false
 dns_lookup_kdc = false
 ticket_lifetime = 24h
 renew_lifetime = 7d
 forwardable = true
#default_keytab_name = /etc/squid/HTTP.keytab
#allow_weak_crypto = yes

; for Windows 2003
      default_tgs_enctypes = rc4-hmac des-cbc-crc des-cbc-md5
      default_tkt_enctypes = rc4-hmac des-cbc-crc des-cbc-md5
      permitted_enctypes = rc4-hmac des-cbc-crc des-cbc-md5

[realms]
 ACCT.SYSNET.LOCAL = {
  kdc = ad01.acct.sysnet.local
  admin_server = ad01.acct.sysnet.local
  kdc = 192.168.8.122
 }

[domain_realm]
 .acct.sysnet.local = DXBPET.SYSNET.LOCAL
 acct.sysnet.local = DXBPET.SYSNET.LOCAL

from squid.conf
