Kerberos Authentication GSS Exception

I have configured kerberos in spring but getting GSS exception as shown in logs below.Going through posts on multiple websites. I think its problem related to keytab file ,kdc or SPN.

Here is how I generated it.

    1)  setspn -s HTTP/seccard-sit1.systems.private srv-seccard-sit1
    2)  setspn -l SYSTEMS\srv-seccard-sit1
    3)  ktpass -out [keytab_seccard-sit1] -princ [HTTP/seccard-sit1.systems.private@SYSTEMS.PRIVATE] -mapUser SYSTEMS\srv-seccard-sit1 -mapOp set -pass [**TBC**] -crypto RC4-HMAC-NT -pType KRB5_NT_PRINCIPAL

And this my krb5.conf

   [libdefaults] 
        default_realm = SYSTEMS.PRIVATE 
        default_tkt_enctypes = aes128-cts rc4-hmac des3-cbc-sha1 des-cbc-md5 des-cbc-crc 
        default_tgs_enctypes = aes128-cts rc4-hmac des3-cbc-sha1 des-cbc-md5 des-cbc-crc 
        permitted_enctypes   = aes128-cts rc4-hmac des3-cbc-sha1 des-cbc-md5 des-cbc-crc 
[realms] 
        SYSTEMS.PRIVATE  = { 

kdc = seccard-sit1.systems.private 
                default_domain = SYSTEMS.PRIVATE 
} 
[domain_realm] 
        .SYSTEMS.PRIVATE = SYSTEMS.PRIVATE
