Modify default behaviour of 'net ads keytab create'
The change modifies the behaviour of 'net ads keytab create' such
that only the keytab file is modified. The current behaviour doesn't
make sense, existing SPN(s) pulled from the computer AD object have
the format 'serviceclass/host:port/servicename'.
'ads_keytab_create_default' calls ads_keytab_add_entry passing
'serviceclass' for each SPN retrieved from the AD. For each
serviceclass passed in a new pair of SPN(s) is generated as follows
i) long form 'param/full_qualified_dns'
ii) short form 'param/netbios_name'
This doesn't make sense as we are creating a new SPN(s) from an existing
one probably replacing the existing host with the 'client' machine.
If the keytab file exists then additionally each kerberos principal in the
keytab file is parsed to strip out the primary, then 'ads_keytab_add_entry'
is called which then tries by default to generate a SPN from any primary
that doesn't end in '$'. By default those SPNs are then added to the AD
computer account for the client running the command.

'net ads keytab add' currently in addition to adding to the
keytab file this command also can update AD computer objects
via ldap. This behaviour isn't very intuitive or expected given
the command name. By default we shouldn't write to the ADS.
Prepare to change the default behaviour by modifying the function
'ads_keytab_add_entry' to take a paramater to modify the existing
behaviour to optionally update the AD (or not).

This patch addresses how the windows SPN is converted into a kerberos
priniciple to be written to the keytab file. A followup patch will
deal with writing Window SPN(s) to the AD.
Before this change 'net ads keytab add' handled three scenarios
a) 'net ads keytab add param' is passed a fully qualified kerberos principal
(identified by the presence of '@' in param) In this scenario the keytab
file alone is updated with the principal contained in 'param'.
b) 'net ads keytab add param'; is passed a machine name (identified by
the paramater ending with '$'). In this case the machine name
is converted to a kerberos principal with according to the recipe
'param@realm' where realm is determined by lp_realm().
c) 'net ads keytab add param' is passed a service (e.g. nfs, http etc.)
In this scenario the param containing the service is first converted to
into 2 kerberos principals (long and short forms) according to the
following recipe
i) long form: 'param/fully_qualified_dns@realm'
ii) short form: 'param/netbios_name@realm'
where 'fully_qualified_dns is retrieved from 'dNSHostName' attribute of
'this' machines computer account on the AD.
The principals are written to the keytab file
Secondly 2 windows SPNs are generated from 'param' as follows
i) long form 'param/full_qualified_dns'
ii) short form 'param/netbios_name'
These SPNs are written to the AD computer account object
After this change a) & b) & c) will retain legacy behaviour except
in the case of c) where if the 'param' passed to c) is a Windows SPN
(e.g. conforming to format 'serviceclass/host:port'
i) 'param' will get converted to a kerberos principal (just a single one)
with the following recipe: 'serviceclass/host@realm' which will
be written to the keytab file. The SPN written to the AD is created
as before and the legacy behaviour is preserved.

In order to prepare for a future patch that will also need to write

need to be changed. Instead of the function creating the SPN(s) it
will now take the list SPN(s) to write to the AD 'machine_name' account
as an input param instead.
The name of the function has been changed to
'ads_add_service_principal_names' to reflect this. Additionally client

that the KDC only has salt-less arcfour-hmac-md5 key together

if the client whould try to use a des key to contact the smb server.

This patch sets dns_lookup_realm=false in samba-generated krb5.conf.
Disabling dns_lookup_realm in krb5.conf is the recommended practice for
Kerberos usage in Active Directory environment. dns_lookup_realm is enabled
by default, at least in Heimdal.
When used by samba, Kerberos libraries operate based on either the system
krb5.conf, or a private krb5.conf generated specifically for the domain by
samba code. In the former case, it's the responsibility of the administrator
to set dns_lookup_realm=false. In the latter case, it's the responsibility
of samba - which is what this patch does.
In many usage scenarios the value of this variable is of no consequence
since samba knows the realm in which it is operating, and knows how to
generate service principal names. However, there are some scenarios
in which samba calls kerberos_get_principal_from_service_hostname(),
and here samba consults the Kerberos libraries and this parameter comes
into play. One primary example is cli_full_connection() function.
Not setting dns_lookup_realm leads to a series of DNS TXT record lookups.
This can be observed by running "net ads join -k -U <user>".
In AD environments, the TXT queries typically fail quickly, but test setups
or misconfigured DNS may lead to large timeouts (for example, if the domain
is dept.example.com but there's no parent example.com domain and no DNS
zones for example.com). At the very least we want to avoid those lookups
because they are hardly documented and lead to confusion.

This is a patch to fix bug 11321.
When finding a domain controller, the method is to resolve
the IP address of candidate servers, and then do an ldap ping until a
suitable server answers.
In case of failure, there's fallback from DNS lookup to netbios lookup
(if netbios is enabled) and then back to site-less DNS lookup. The two
problems here are:
1. It makes more sense to try site-less DNS before NetBIOS because the
fallback to NetBIOS is not likely to give better results.
2. The NetBIOS fallback screws the site-less fallback (I suppose the
"goto considered harmful fellows are sometimes right after all...).
This fix extracts the core code that does name resolving+ldap ping
into a separate function and then activates this function in up to
three modes - site-aware, site-less, and netbios, in that order.

When creating a custom krb.conf file for a domain, make sure
that the DC which already answered the ldap ping is not queried
again, and is always first in the custom KDC list. This has two
advantages:
1. Avoid re-sending an ldap ping to this server
2. The generated list is made up of the servers that answered
first. Since the DC which already answered an LDAP ping
is typically the "last good server", this change keeps it
out of the contest and guarantees that we keep using last
good server as long as it works.

When updating the system keytab as a result of joining a domain,
if the keytb had prior entries, ads_keytab_create_default tries to
update those entries. However, it starts updating before freeing the
cursor which was used for finding those entries, and hence causes
an an attempt to write-lock the keytab while a read-lock exists.
