Hi all, about environment: Squid version = squid-3.0.STABLE8 Active Directory Windows 2003 Linux Redhat EL 5 I´m trying using kerberos auth with squid_kerb_auth looking for http://klaubert.wordpress.com/2008/01/09/squid-kerberos-authentication-and-ldap-authorization-in-active-directory/ (anyone have used it ?) I have used this options to create keytab file on AD server as domain admin: C:\>ktpass -princ HTTP/DOMAIN.COM.BR@REALM -mapuser domain_rj\squid_user -crypto D ES-CBC-CRC -ptype KRB5_NT_PRINCIPAL -pass *password* -out squid.DOMAIN.COM.BR.keytab after export it to Linux box and try the initial test, I got it: [root@boom etc]# kinit -V -k -t squid.domain.COM.BR.keytab domain.COM.BR kinit(v5): Client not found in Kerberos database while getting initial credentials googling this error I found a possible solution: kinit: Client not found in Kerberos database while getting initial credentials. Meaning: The principal whose credentials are being requested does not exist in the Kerberos database. Reason or Active corretion: Verify there is a principal entry available for the client in the Kerberos database; if not create the same Question: So, what is wrong and how can get it working ?
