      Maybe you are facing the same problem as this guy was, take a look:

      http://squid-web-proxy-cache.1019090.n4.nabble.com/squid-kerb-auth-received-type-1-NTLM-token-td2131613.html

      Quote:
      You should see a request from the client to Active Directory asking for a TGS for HTTP/<fqdn of proxy>. If that does not happen or get refused by AD the client will fall back to NTLM (wrapped into the Negotiate response) which is waht you see on the proxy.

      I would set a packet capture like that guy did to check, port 88

          Why are you authenticating as administrador@CASA.LOCAL ?
          The user should be appearing there and not administrator. Should be user@CASA.LOCAL

          The user need to be member of the group used in ldapusersearch in Squidguard

              Ok, in this last screenshot, the username is Windows10?
              Is this user a member of the group used in ldapusersearch?

              You are almost there.. soon we will find the problem

                thanks for the reply,
                so on the squidguard

                ldapusersearch ldap://apolo.casa.local:3268/dc=casa,dc=local?userPrincipalName?sub?(&(memberof=%2cCN=Users%2cDC=casa%2cDC=local)(userPrincipalName=%s))

                and the user is located in

                CN=windows10,CN=Users,DC=casa,DC=local

                  ldapusersearch ldap://apolo.casa.local:3268/dc=casa,dc=local?userPrincipalName?sub?(&(memberof=%2cCN=Users%2cDC=casa%2cDC=local)(userPrincipalName=%s))

                  You used a %2c in the wrong place (It means a ',')

                  It should be:

                  ldapusersearch ldap://apolo.casa.local:3268/dc=casa,dc=local?userPrincipalName?sub?(&(memberof=CN=Users%2cDC=casa%2cDC=local)(userPrincipalName=%s))

                  It's important to notice that you are not filtering users by group in this case..
                  I would create a group, like internet, add the members to this group, and then filter like this:

                  ldapusersearch ldap://apolo.casa.local:3268/dc=casa,dc=local?userPrincipalName?sub?(&(memberof=CN=internet%2cCN=Users%2cDC=casa%2cDC=local)(userPrincipalName=%s))

                    @mcury said in Kerberos Squid without authentication?:

                    ldapusersearch ldap://apolo.casa.local:3268/dc=casa,dc=local?userPrincipalName?sub?(&(memberof=CN=internet%2cCN=Users%2cDC=casa%2cDC=local)(userPrincipalName=%s))

                    Thanks again for the reply, so i changed to

                    ldapusersearch ldap://apolo.casa.local:3268/dc=casa,dc=local?userPrincipalName?sub?(&(memberof=CN=internet%2cCN=Users%2cDC=casa%2cDC=local)(userPrincipalName=%s))

                    then created group called internet added windows10 and administrador but same issue with popup

                    CN=internet,CN=Users,DC=casa,DC=local

                    Im thinking its a squid issue but dont know what else to do :(

                      Try port 389 instead of 3268.. Who knows..

                        (squidGuard): ldap_search_ext_s failed: Operations error (params: dc=casa,dc=local, 2, (&(memberof=CN=internet,CN=Users,DC=casa,DC=local)(userPrincipalName=administrador)),

                        i also had to configure on squidguard

                          So, is it working now ?

                          if not, I would focus on the ldapusersearch..

                              Try to tick that option in squidguard: Strip NT domain name.
                              If ticking it doesn't work, undo it..

                                Test this:

                                1 - Disable Squidguard authentication tab
                                2 - Enable Squid authentication tab with the following details:

                                Squid Authentication LDAP Settings > LDAP Base Domain:
                                DC=casa,DC=local -R

                                (-R option will enable the recursive search in domain).

                                Note: keep the ldapusersearch the same as before, using port 3268

                                Then try again and post here in case it works.

                                  Google Chrome and other browsers from a certain version onwards (I can't say from which one) don't allow "Transparent" authentication without the Pop Up window appearing.
                                  So I don't think you will be able to accomplish what you intended.

                                  If I am wrong can you correct me please.
