$ kadmin -r TEST.ME -p admin/admin@TEST.ME
Authenticating as principal admin/admin@TEST.ME with password.
kadmin: ktadd -k sopwith.keytab sopwith@TEST.ME
Entry for principal sopwith@TEST.ME with kvno 3, encryption type DES cbc
mode with CRC-32 added to keytab WRFILE:sopwith.keytab Entry for principal
sopwith@TEST.ME with kvno 3, encryption type Triple DES cbc mode raw added
to keytab WRFILE:sopwith.keytab
$ kinit -k host/ath.test.me@TEST.ME
kinit(v5): Bad encryption type while getting initial credentials
While possibly caused by operator error, the instructions available seem to
indicate that this should work. Using kinit on this same principal with the
password instead of the keytab file works fine. This happens on both Alpha
and x86 archs - the alpha is using krb5-*-1.2.2-3, the x86 krb5-*-1.2.1-8.
This is a partially-implemented feature. Currently, kinit using a keytab
only works for DES, not 3DES. To extract just a DES key, use the
"ktadd -e des <principal>" syntax in kadmin. I expect this will be fixed in
a future release of Kerberos 5.
