Pretty sure I did that:
I ran the command
ksetup /mapuser [email protected] username

The principal was created using:
ank -pw password -e rc4-hmac:normal host/minimepc.m.domain.com

For all account it seemed to work properly, by that I mean I see no
authentication error in the kdc logs.

Do the DES encryption types need to be enabled even for Windows 7 ?

I did see:

Sep 22 05:43:06 m.domain.com krb5kdc[68](info): AS_REQ (7 etypes {18
17 16 23 1 3 2}) 60.242.X.X: NEEDED_PREAUTH:
[email protected] for krbtgt/[email protected],
Additional pre-authentication required

followed by proper authentication after, no password errors.
