221c1512a8 r12411: Add 'net samdump keytab <keytab>'.
This extracts a remote windows domain into a keytab, suitable for use
in ethereal for kerberos decryption.

For the moment, like net samdump and net samsync, the 'password
server' smb.conf option must be set to the binding string for the
server. eg:

password server = ncacn_np:mypdc

a1827a1deb r12227: I realised that I wasn't yet seeing authenticated LDAP for the ldb
backend.

The idea is that every time we open an LDB, we can provide a
session_info and/or credentials.  This would allow any ldb to be remote
to LDAP.  We should also support provisioning to a authenticated ldap
server.

(They are separate so we can say authenticate as foo for remote, but
here we just want a token of SYSTEM).

9c6b7f2d62 r11995: A big kerberos-related update.
This merges Samba4 up to current lorikeet-heimdal, which includes a
replacement for some Samba-specific hacks.

In particular, the credentials system now supplies GSS client and
server credentials.  These are imported into GSS with
gss_krb5_import_creds().  Unfortunetly this can't take an MEMORY
keytab, so we now create a FILE based keytab as provision and join
time.

Because the keytab is now created in advance, we don't spend .4s at
negprot doing sha1 s2k calls.  Also, because the keytab is read in
real time, any change in the server key will be correctly picked up by
the the krb5 code.

To mark entries in the secrets which should be exported to a keytab,
there is a new kerberosSecret objectClass.  The new routine
cli_credentials_update_all_keytabs() searches for these, and updates
the keytabs.

This is called in the provision.js via the ejs wrapper
credentials_update_all_keytabs().

We can now (in theory) use a system-provided /etc/krb5.keytab, if

krb5Keytab: FILE:/etc/krb5.keytab

is added to the secrets.ldb record.  By default the attribute

privateKeytab: secrets.keytab

is set, pointing to allow the whole private directory to be moved
without breaking the internal links.

cfa2adf040 r11401: A simple hack to have our central credentials system deny sending LM
authentication for user@realm logins and machine account logins.

This should avoid various protocol downgrade attacks.

b0c7c175b1 r11220: Add the ability to handle the salt prinicpal as part of the
credentials.  This works with the setup/secrets.ldif change from the
previous patch, and pretty much just re-invents the keytab.

Needed for kpasswdd work.

372ca26b20 r11200: Reposition the creation of the kerberos keytab for GSSAPI and Krb5
authentication.  This pulls the creating of the keytab back to the
credentials code, and removes the special case of 'use keberos keytab
= yes' for now.

This allows (and requires) the callers to specify the credentials for
the server credentails to GENSEC.  This allows kpasswdd (soon to be
added) to use a different set of kerberos credentials.

The 'use kerberos keytab' code will be moved into the credentials
layer, as the layers below now expect a keytab.

We also now allow for the old secret to be stored into the
credentials, allowing service password changes.
