I have configured my RHEL linux machine to be authenticated against active directory without being joining it to domain, using nss-pam-ldapd pam_ldap samba-winbind openldap-devel krb5-devel. I am able to login on linux machines using active directory accounts, but I am not sure if the kerberos is being used during authentication, because I dont see the TGT in linux machine's local cache, but when I use "kinit username" and then check with klist I do see the TGT. I am little confused, on how to confirm if the kerberos is being used or not.
Thanks, Subodh.
