Pfsense 2.2.6 + squid+kerberos

[rgibox]

Hi,
I'm trying to implement squid with AD SSO.
I Installed pfsense 2.2.6+squid and krb5 package.
And created krb5.conf and keytab file.

[libdefaults]
         default_realm = RG.LOCAL
         dns_lookup_kdc = no
         dns_lookup_realm = no
         ticket_lifetime = 24h
         default_keytab_name = /etc/proxy.keytab
         default_tgs_enctypes = AES256-CTS-HMAC-SHA1-96 RC4-HMAC DES-CBC-CRC DES-CBC-MD5
         default_tkt_enctypes = AES256-CTS-HMAC-SHA1-96 RC4-HMAC DES-CBC-CRC DES-CBC-MD5
         permitted_enctypes = AES256-CTS-HMAC-SHA1-96 RC4-HMAC DES-CBC-CRC DES-CBC-MD5
 [realms]
         RG.LOCAL = {
                 kdc = 192.168.204.5
                 kdc = 192.168.204.6
				 admin_server = 192.168.204.5
                 default_domain = rg.local
         }
  [domain_realm]
         .rg.local = RG.LOCAL
         rg.local = RG.LOCAL

I'm able to get ticket with kinit.
But when i'm trying to do test with:
/usr/pbi/squid-amd64/local/libexec/squid/negotiate_kerberos_auth_test -r -s HTTP/proxy.rg.local@RG.LOCAL

I get this

2016/01/20 09:49:14 kid1| Starting Squid Cache version 3.4.10 for amd64-portbld-freebsd10.1...
2016/01/20 09:49:14| pinger: Initialising ICMP pinger ...
dlopen: Cannot open "/usr/lib/libgssapi_spnego.so.10"

Where can i find this file?
Is there a working instruction for 2.2.6+kerberos?

PS: sorry for my english.
