The keytab isn't valid for the host as it doesn't contain a usable principal
for doing a validation of the KDC.  The pam_krb5 rpm has sensibly changed the
default for validate from false to true.  Try adding:

  pam = {
    novalidate = true

I /think/ that'd work, but you'd be less secure than if you just sorted out
your keytab.  Get a real principal for your domain into the keytab, and
validate will work.  You're using LAB-LPP.LOCAL, but only have principals from
TEST-LPP.LOCAL in your keytab.
