[Pkg-samba-maint] Bug#519570: Type of encryption

[Eduardo Sachs]

- The Heimdal Kerberos don't have support for encryption type 23, 23 is
RC4-HMAC.

- Samba 3.2.x and 3.3.x try use only encryption type 23.

- After of join the Samba Member in Domain with the command 'net join',
I can't more access the Samba Member it through of the Kerberos
authentication,
but, if I delete the file /var/lib/samba/secrets.tdb of Samba Member and
restarting,
after this, the Kerberos authentication back to operate normally.

- I think some keys saves on "secrets.tdb" in encryption type RC4-HMAC,
and can't decrypt with Heimdal, because the Heimdal don't
support encryption of type RC4-HMAC.

- In Samba 3.0.x try use other type encryption, and is not RC4-HMAC.

Thanks!
