Do not use DES- it's not secure and there's no reason to use it. Use
AES instead.

This is the problem- with Kerberos and GSSAPI, you need to have a
'service' princ (that's the POSTGRES/my.host.name one) *and* a 'user'
princ (in your case, that should be 'enterprisedb'). The 'service'
princ needs to be exported as a keytab, as you've done, and then made
available to the PostgreSQL server (which I think you've done).
However, the 'user' princ should acquire credentials through a normal
'kinit' (which is what happens when a user logs on to a Windows system
with AD).

Right, this is telling you that you're using a principal
(POSTGRES/centos) which doesn't match the user that you're trying to
authenticate as ('enterprisedb').
