I forgot this link to an Example configuration: http://wiki.squid-cache.org/ConfigExamples/Authenticate/Kerberos 2010/4/8 Khaled Blah <khaled.blah@xxxxxxxxxxxxxx>: > Hi Bilal, > > 1. ktpass and msktutil practically do the same, they create keytabs > which include the keys that squid will need to decrypt the ticket it > receives from the user.
