I am setting up a testbed environment where Linux (Ubuntu 10.04) clients will authenticate to a Windows Server 2008 R2 Domain Server.
LOCAL [unpack_buffer] (0x0100): cmd  uid  gid  validate [false] offline [false] UPN [[email protected]
You have a single AD domain but users can have additional user principal names (UPN) associated, so in addition to XXXX. You may be interested to look for details at https://bugzilla.redhat.com/show_bug.cgi? Add a realm section in your krb5like this and see what happens. However, I'm not sure this is really the right thing. LOCAL realm, trying to figure out why sssd is ignoring that might lead you more in the correct direction. I was already connected to the domain, but I kept seeing the error kinit-succeeded-but-ads_sasl_spnego_krb5_bind-failed in my logs.
Kerberos requires that all the computers in the environment have system times within 5 minutes of one another.
If computers that a client is attempting to use for either initial authentication (the Kerberos server) or resource access (including both the application server and, in a cross-realm environment, an alternate Kerberos server) have a delta greater than 5 minutes from the client computer or from one another, the Kerberos authentication will fail.
