dblookup.c
Abstract:
LSA Database - Lookup Sid and Name routines
NOTE: This module should remain as portable code that is independent
of the implementation of the LSA Database. As such, it is
permitted to use only the exported LSA Database interfaces
contained in db.h and NOT the private implementation
dependent functions in dbp.h.

Routine Description:
This routine is the LSA Server worker routine for the LsaLookupSids
API.
The LsaLookupSids API attempts to find names corresponding to Sids.
If a name can not be mapped to a Sid, the Sid is converted to character
form. The caller must have POLICY_LOOKUP_NAMES access to the Policy
object.
WARNING: This routine allocates memory for its output. The caller is
responsible for freeing this memory after use. See description of the
Names parameter.
Arguments:
PolicyHandle - Handle from an LsaOpenPolicy call.
SidEnumBuffer - Pointer to an enumeration buffer containing a count
and a pointer to an array of Count pointers to Sids to be mapped
to names. The Sids may be well_known SIDs, SIDs of User accounts
Group Accounts, Alias accounts, or Domains.
ReferencedDomains - Receives a pointer to a structure describing the
domains used for the translation. The entries in this structure
are referenced by the structure returned via the Names parameter.
Unlike the Names parameter, which contains an array entry
for (each translated name, this strutcure will only contain
component for each domain utilized in the translation.
When this information is no longer needed, it must be released
by passing the returned pointer to LsaFreeMemory().
TranslatedNames - Pointer to a structure which will reference an array
records describing each translated name. The nth entry in this array
provides a translation for the nth entry in the Sids parameter.
All of the returned names will be isolated names or NULL strings
(domain names are returned as NULL strings). If the caller needs
composite names, they can be generated by prepending the
isolated name with the domain name and a backslash. For example,
if (the name Sally is returned, and it is from the domain Manufact,
then the composite name would be "Manufact" + "\" + "Sally" or
"Manufact\Sally".
When this information is no longer needed, it must be released
by passing the returned pointer to LsaFreeMemory().
If a Sid is not translatable, then the following will occur:
1) If the SID's domain is known, then a reference domain record
will be generated with the domain's name. In this case, the
name returned via the Names parameter is a Unicode representation
of the relative ID of the account, such as "(3cmd14)" or the null
string, if the Sid is that of a domain. So, you might end up
with a resultant name of "Manufact\(314) for the example with
Sally above, if Sally's relative id is 314.
2) If not even the SID's domain could be located, then a full
Unicode representation of the SID is generated and no domain
record is referenced. In this case, the returned string might
be something like: "(S-1-672194-21-314)".
When this information is no longer needed, it must be released
by passing the returned pointer to LsaFreeMemory().
LookupLevel - Specifies the Level of Lookup to be performed on this
machine. Values of this field are are follows:
LsapLookupWksta - First Level Lookup performed on a workstation
normally configured for Windows-Nt. The lookup searches the
Well-Known Sids/Names, and the Built-in Domain and Account Domain
in the local SAM Database. If not all Sids or Names are
identified, performs a "handoff" of a Second level Lookup to the
LSA running on a Controller for the workstation's Primary Domain
(if any).
LsapLookupPDC - Second Level Lookup performed on a Primary Domain
Controller. The lookup searches the Account Domain of the
SAM Database on the controller. If not all Sids or Names are
found, the Trusted Domain List (TDL) is obtained from the
LSA's Policy Database and Third Level lookups are performed
via "handoff" to each Trusted Domain in the List.
LsapLookupTDL - Third Level Lookup performed on a controller
for a Trusted Domain. The lookup searches the Account Domain of
the SAM Database on the controller only.
MappedCount - Pointer to location that contains a count of the Sids
mapped so far. On exit, this will be updated.
LookupOptions - flags to control the lookup. Currently non defined
ClientRevision -- the version of the client
Return Values:
NTSTATUS - Standard Nt Result Code
STATUS_SUCCESS - The call completed successfully and all Sids have
been translated to names.
STATUS_SOME_NOT_MAPPED - At least one of the Sids provided was
translated to a Name, but not all Sids could be translated. This
is a success status.
STATUS_NONE_MAPPED - None of the Sids provided could be translated
to names. This is an error status, but output is returned. Such
output includes partial translations of Sids whose domain could
be identified, together with their Relative Id in Unicode format,
and character representations of Sids whose domain could not
be identified.
STATUS_ACCESS_DENIED - Caller does not have the appropriate access
to complete the operation.
STATUS_DOMAIN_CTRLR_CONFIG_ERROR - Target machine not configured
as a DC when expected.
STATUS_INSUFFICIENT_RESOURCES - Insufficient system resources
such as memory to complete the call.

Routine Description:
This function enumerates Sids of objects of a given type within a container
object. Since there may be more information than can be returned in a
single call of the routine, multiple calls can be made to get all of the
information. To support this feature, the caller is provided with a
handle that can be used across calls. On the initial call,
EnumerationContext should point to a variable that has been initialized
to 0.
Arguments:
ContainerHandle - Handle to a container object.
ObjectTypeId - Type of object to be enumerated. The type must be one
for which all objects have Sids.
EnumerationContext - API-specific handle to allow multiple calls
(see Routine Description above).
DbEnumerationBuffer - Receives a pointer to a structure that will receive
the count of entries returned in an enumeration information array, and
a pointer to the array. Currently, the only information returned is
the object Sids. These Sids may be used together with object type to
open the objects and obtain any further information available.
PreferedMaximumLength - prefered maximum length of returned data (in 8-bit
bytes). This is not a hard upper limit, but serves as a guide. Due to
data conversion between systems with different natural data sizes, the
actual amount of data returned may be greater than this value.
CountReturned - Pointer to variable which will receive a count of the
entries returned.
Return Values:
NTSTATUS - Standard Nt Result Code
STATUS_ACCESS_DENIED - Caller does not have the appropriate access
to complete the operation.
STATUS_NO_MORE_ENTRIES - There are no more entries. This warning
is returned if no objects have been enumerated because the
EnumerationContext value passed in is too high.

Routine Description:

(Well-Known Sids that do not belong to a domain) and translate them to
names. Note that Domain Sids for the Well Known domains themselves
(e.g the Sid of the Built-in Domain) will be identified.
WARNING: This function allocates memory for translated names. The
caller is responsible for freeing this memory after it is no longer
required.
Arguments:
Count - Specifies the count of Sids provided in the array Sids.
Sids - Pointer to an array of Sids to be examined.
TranslatedNames - Pointer to structure that will be initialized to
references an array of Name translations for the Sids.
ReferencedDomains - Pointer to a structure that will be initialized to
reference a list of the domains used for the translation.
The entries in this structure are referenced by the
structure returned via the Names parameter. Unlike the Names
parameter, which contains an array entry for (each translated name,
this structure will only contain one component for each domain
utilized in the translation.
If the specified location contains NULL, a structure will be allocated
via MIDL_user_allocate.
MappedCount - Pointer to location that contains on entry, the number
of Sids in Sids that have been translated so far. This number
is updated if any further Sids are translated by this call.
CompletelyUnmappedCount - Pointer to location containing the
count of completely unmapped Sids. A Sid is completely unmapped
if it is unknown and also its Domain Prefix Sid is not recognized.
This count is updated on exit, the number of completely unmapped
Sids whose Domain Prefices are identified by this routine being
subtracted from the input value.
Return Value:
NTSTATUS - Standard Nt Result Code
STATUS_SUCCESS - The call completed successfully. Note that some
or all of the Sids may remain partially or completely unmapped.

Routine Description:
This function looks up Sids in the local SAM domains and attempts to
translate them to names. Currently, there are two local SAM domains,
the Built-in domain (which has a well-known Sid and name) and the
Account Domain (which has a configurable Sid and name).
Arguments:
Count - Number of Sids in the Sids array, Note that some of these
may already have been mapped elsewhere, as specified by the
MappedCount parameter.
Sids - Pointer to array of pointers to Sids to be translated.
Zero or all of the Sids may already have been translated
elsewhere. If any of the Sids have been translated, the
Names parameter will point to a location containing a non-NULL
array of Name translation structures corresponding to the
Sids. If the nth Sid has been translated, the nth name
translation structure will contain either a non-NULL name
or a non-negative offset into the Referenced Domain List. If
the nth Sid has not yet been translated, the nth name
translation structure will contain a zero-length name string
and a negative value for the Referenced Domain List index.
ReferencedDomains - Pointer to a structure in which the list of domains
used in the translation is maintained. The entries in this structure
are referenced by the structure returned via the Sids parameter.
Unlike the Sids parameter, which contains an array entry for each
translated name, this structure will only contain one component for
each domain utilized in the translation.
TranslatedNames - Pointer to a structure in which the translations to Names
corresponding to the Sids specified on Sids is maintained. The
nth entry in this array provides a translation (where known) for the
nth element in the Sids parameter.
MappedCount - Pointer to location in which a count of the Names that
have been completely translated is maintained.
CompletelyUnmappedCount - Pointer to a location in which a count of the
Names that have not been translated (either partially, by identification
of a Domain Prefix, or completely) is maintained.
Options - Specifies optional actions.
LSAP_DB_SEARCH_BUILT_IN_DOMAIN - Search the Built In Domain
LSAP_DB_SEARCH_ACCOUNT_DOMAIN - Search the Account Domain
Return Values:
NTSTATUS - Standard Nt Result Code
STATUS_SUCCESS - The call completed successfully. Note that some

STATUS_INSUFFICIENT_RESOURCES - Insufficient system resources,

Routine Description:
This function attempts to translate Sids in a Primary Domain. A
Trusted Domain object must exist for the domain in the local Policy
Database. This object will be used to access the Domain's list of
Controllers and one or more callouts will be made to access the LSA
Policy Databases on these Controllers.
Arguments:
Count - Number of Sids in the Sids array, Note that some of these
may already have been mapped elsewhere, as specified by the
MappedCount parameter.
Sids - Pointer to array of pointers to Sids to be translated.
Zero or all of the Sids may already have been translated
elsewhere. dd esp la If any of the Sids have been translated, the
Names parameter will point to a location containing a non-NULL
array of Name translation structures corresponding to the
Sids. If the nth Sid has been translated, the nth name
translation structure will contain either a non-NULL name
or a non-negative offset into the Referenced Domain List. If
the nth Sid has not yet been translated, the nth name
translation structure will contain a zero-length name string
and a negative value for the Referenced Domain List index.
TrustInformation - Specifies the name and Sid of the Primary Domain.
ReferencedDomains - Pointer to a structure in which the list of domains
used in the translation is maintained. The entries in this structure
are referenced by the structure returned via the Sids parameter.
Unlike the Sids parameter, which contains an array entry for each
translated name, this structure will only contain one component for
each domain utilized in the translation.
TranslatedNames - Pointer to a structure in which the translations to Names
corresponding to the Sids specified on Sids is maintained. The
nth entry in this array provides a translation (where known) for the
nth element in the Sids parameter.
LookupLevel - Specifies the Level of Lookup to be performed on this
machine. Values of this field are are follows:
LsapLookupPDC - Second Level Lookup performed on a Primary Domain
Controller. The lookup searches the Account Domain of the
SAM Database on the controller. If not all Sids or Names are
found, the Trusted Domain List (TDL) is obtained from the
LSA's Policy Database and Third Level lookups are performed
via "handoff" to each Trusted Domain in the List.
LsapLookupTDL - Third Level Lookup performed on a controller
for a Trusted Domain. The lookup searches the Account Domain of
the SAM Database on the controller only.
NOTE: LsapLookupWksta is not valid for this parameter.
MappedCount - Pointer to location in which a count of the Names that
have been completely translated is maintained.
CompletelyUnmappedCount - Pointer to a location in which a count of the
Names that have not been translated (either partially, by identification
of a Domain Prefix, or completely) is maintained.
NonFatalStatus - a status to indicate reasons why no sids could have been
resolved
fDownlevelSecureChannel - TRUE if secure channel DC is nt4 or below; FALSE
otherwise
Return Values:
NTSTATUS - Standard Nt Result Code
STATUS_SUCCESS - The call completed successfully. Note that some
or all of the Sids may remain partially or completely unmapped.
STATUS_INSUFFICIENT_RESOURCES - Insufficient system resources,
such as memory, to complete the call.

Routine Description:
This routine tries to match entries in Sids to domain Sids of
trusted domains.
There are three kinds of trusted domains:
1) domains we directly trusts (both in and out of forest). The LSA TDL
is used for this.
2) domains we trust transitively. The DS cross-ref is used for this.
3) domains we trust via a forest trust. The LSA TDL is used
for this.
Arguments:
Flags -- LSAP_LOOKUP_TRUSTED_DOMAIN_DIRECT
LSAP_LOOKUP_TRUSTED_DOMAIN_TRANSITIVE
LSAP_LOOKUP_TRUSTED_DOMAIN_FOREST_NAMES
Count -- the number of entries in Sids
Sids -- the SID's belonging to a XForest domain
ReferencedDomains -- the domains of Sids
TranslatedNames -- the names and characteristics of Sids
Mapped -- the number of Sids that have been fully mapped
Return Values:
STATUS_SUCCESS, or resource error otherwise
