Incompatibility between krb's AES256-CTS-HMAC-SHA1-96 and Microsoft Windows Domain

[Ido Shlomo]

The thing is that kinit works well for the user (not computer)
The problem is that I register an SPN on the DC for that user (again, not
computer) using ldap, and then I resgister the same SPN
(MSSQL/mymachine.domain.com:1433 at DOMAIN.COM). The problem occurs when an
incoming connection gives me a token that I cannot accept. The error is
that I cannot decrypt it.

You can try an AS request where the KDC tells the salt, like:
# KRB5_TRACE=/dev/tty kinit principal

btw, for user-account in AD the salt is the UPN attribute of the user.
