How I am supposed to configure Kerberos on OS X 10.8 ? I heard that this should work by default, just by calling kinit once.

Still, I am on the corporate network (not joined any domain) and run kinit.

All, I got was kinit: krb5_get_init_creds: unable to reach any KDC in realm LOCAL

Note: I do want to make it work without having to join the Windows domain.

/var/log/opendirectory.log shows:

2012-09-05 14:05:16.600904 BST - 81.144675 - Client: mds, UID: 0, EUID: 0, GID: 0, EGID: 0
2012-09-05 14:05:16.600904 BST - 81.144675, Module: SystemCache - Misconfiguration detected - Failed to insert key 'ABCDEFAB-CDEF-ABCD-EFAB-CDEF00000037' for entry '0x7fbf0fa01140' into hash 'UUID' as 'non-authoritative'

On macOS the default client does not fall back to TCP.

In your krb.conf prefix your kdc value with tcp/ to force the client to use TCP if your corporate network blocks UDP (A lot of them do).

kdc = tcp/realm.example.com:88
