So I have a strange Kerberos problem trying to figure out.  On a
CLIENT,  (CentOS 7.1) if I login to account "usera" they get a
ticket as
expected.  However, if I login to a 6.6 client, it doesn't seem to
Both were enrolled the same, obviously one is newer.

Now, it gets stranger. The "servers" are CentOS 7.1 also. If I login
root, bypassing kerberos, and then do "kinit admin" it works just
But if I do "kinit usera" I get:

kinit: Generic preauthentication failure while getting initial

Which makes no sense. The account works with a 7.1 client but not a
client?? And yet "admin" works, no matter what. What am I missing
If I had to guess, usera is enabled for OTP-only login. Is that

If so, clients require RHEL 7.1 for OTP support. Also, the error you
are getting is the result of not enabling FAST support for OTP
authentication (see the -T option).

Apparently I am not being clear. The user account can login all over the place with no problems -- RHEL 7.1 or 6.6. HOWEVER, on 7.1, a login provides a direct tgt, but no matter what you do on any other host using kinit (after logging in with an SSH key perhaps or as another user) and even know the password, you get this error.

Again, logging in with the password, not OTP, works just fine.
