8f078cdf24 dsdb: Ensure "authenticated users" is processed for group memberships
This change moves the addition of "Authenticated Users" from the very end of the
token processing to the start.  The reason is that we need to see if
"Authenticated Users" is a member of other builtin groups, just as we
would for any other SID.  This picks up the "Pre-Windows 2000 Compatible Access"
group, which is in turn often used in ACLs on LDAP objects.

Without this change, the eventual token does not contain S-1-5-32-554
and users other than "Administrator" are unable to read uidNumber
(in particular).

18692b060f s4-auth: Make sure we use the correct credential state.
If we create a copy of the credential state we miss updates to the
credentials.

To establish a netlogon schannel connection we create client credentials
and authenticate with them using

dcerpc_netr_ServerAuthenticate2()

For this we call netlogon_creds_client_authenticator() which increases
the sequence number and steps the credentials. Lets assume the sequence
number is 1002.

After a successful authentication we get the server credentials and we
send bind a auth request with the received creds. This sets up gensec
and the gensec schannel module created a copy of the client creds and
stores it in the schannel auth state. So the creds stored in gensec have
the sequence number 1002.

After that we continue and need the client credentials to call

dcerpc_netr_LogonGetCapabilities()

to verify the connection. So we need to increase the sequence number of
the credentials to 1004 and step the credentials to the next state. The
server always does the same and everything is just fine here.

The connection is established and we want to do another netlogon call.
So we get the creds from gensec and want to do a netlogon call e.g.

dcerpc_netr_SamLogonWithFlags.

We get the needed creds from gensec. The sequence number is 1002 and
we talk to the server. The server is already ahead cause we are already
at sequence number 1004 and the server expects it to be 1006. So the
server gives us ACCESS_DENIED cause we use a copy in gensec.

so if we ever did use a module that needed this functionlity, we would
downgrade to just NTLM.

Now that security=server has been removed, we have no such module.

This will make it easier to make the auth subsystem async, as we will
