These functions make it possible to construct a full auth_session_info
from the information available from an auth_user_info_dc structure.
This has all the logic from create_local_token() that is used
to transform a auth_serversupplied_info to a full auth_session_info.
In order to workarround the restriction that auth_user_info_dc
doesn't contain hints for the unix token/name, we use
the special S-1-5-88 (Unix_NFS) sids:
- S-1-5-88-1-Y gives the uid=Y
- S-1-5-88-2-Y gives the gid=Y
- S-1-5-88-3-Y gives flags=Y AUTH3_UNIX_HINT_*
The currently implemented flags are:
- AUTH3_UNIX_HINT_QUALIFIED_NAME
unix_name = DOMAIN+ACCOUNT
- AUTH3_UNIX_HINT_ISLOLATED_NAME
unix_name = ACCOUNT
- AUTH3_UNIX_HINT_DONT_TRANSLATE_FROM_SIDS
Don't translate the nt token SIDS into uid/gids
using sid mapping.
- AUTH3_UNIX_HINT_DONT_TRANSLATE_TO_SIDS
Don't translate the unix token uid/gids to S-1-22-X-Y SIDS
- AUTH3_UNIX_HINT_DONT_EXPAND_UNIX_GROUPS
The unix token won't get expanded gid values
from getgroups_unix_user()
By using the hints it is possible to keep the current logic
where an authentication backend provides uid/gid values and
the unix name.
Note the S-1-5-88-* SIDS never appear in the final security_token.

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.

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

be written to the keytab file. The SPN written to the AD is created
as before and the legacy behaviour is preserved.

Previously the function 'ads_add_service_principal_name' created
the SPNs based on the machine_name and dns name passed to the function.
In order to prepare for a future patch that will also need to write
SPN(s) to the AD computer account, the function implementation will
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
code now needs to construct the SPNs to be passed into the function.

Function 'ads_get_samaccountname()' basically returns the machine_name passed
as an input param (appended with '$') if it exists on the ad. The function
really is testing for the existence of the samaccountname and is not really
'getting' it. This is also the way it is used. Renaming this function to
'ads_has_samaccountname()' better reflects what it is actually doing and how
clients calling the code use it. It also makes the client code using calling
this function less confusing.

Fix a bug when a child dies when a request is pending in the child. If the
signal handler fires before epoll finds out the other end of the parent-child
socket is closed, we close the socket on our side without taking care of the
pending request. This causes two problems: First, that one pending request
never is replied to properly, and secondly, we might end up with EPOLL_DEL on a
wrong file descriptor. This causes all sorts of trouble if we hit an active
one.
The fix for this problem is not to close the socket in winbind_child_died().
This however stops an idle child that dies hard from being properly cleaned up.
The fix for that is to add the child->monitor_fde that is set pending only when
no child request is active. This way we can remove the close(sock) in the
signal handler.

Commit ed3bc614cc got the logic wrong while
trying to implement the logic we had in init_child_connection(),
which was removed by commit d61f3626b7.
Instead of doing a WINBINDD_GETDCNAME request (which would caused an error
because the implementation was removed in commit
958fdaf5c3), we sent the callers request
and interpreted the result as WINBINDD_GETDCNAME response, which
led to an empty dcname variable. As result the domain child
opened a connection to the primary domain in order to lookup
a dc.
If we want to connect the primary domain from the parent via
a domain child of the primary domain.
