RE: [squid-users] Re: Re: SSO with Active Directory-Squid Clients

If i select negotiate/Kerberos as authentication protocol for my Squid on Linux and configure no FallBack Authentication.what would be the consequence ?
 
 
 
1. Isnt it that all of my users who have logged into Active Directory and where browser is supported will be able to use squid?
 
 
 
2. Only those users who will try to use squid from a workgroup giving their domain passoword (domainname/userid) will fail as there will be no fallback aviablable.
 
 
 
3. Is there any other scenario in which these users will not be able to use squid?
 
 
 
I would be really thankful if you guide me further as i am failing to understand why a fallback authentication is necessary if it is. What could be the scenario when windows clients have no valid TGT even if they are login to the domain? I hope you can understand me and help me to clear my self.
