// Behavior of the possible combinations are outlined below.

// DomainControllerName(value), DnsDomainName(NULL)

//      The value for DomainControllerName is assumed to have been
//      obtained via DsGetDcName (i.e. Field with the same name in a
//      DOMAIN_CONTROLLER_INFO struct on return from DsGetDcName call.)
//      The client is bound to the domain controller at this name.
//
//      Mutual authentication will be performed using an SPN of
//      LDAP/DomainControllerName provided DomainControllerName
//      is not a NETBIOS name or IP address - i.e. it must be a
//      DNS host name.
//
// DomainControllerName(value), DnsDomainName(value)
//
//      DsBind will connect to the server identified by DomainControllerName.
//
//      Mutual authentication will be performed using an SPN of
//      LDAP/DomainControllerName/DnsDomainName provided neither value
//      is a NETBIOS names or IP address - i.e. they must be
//      valid DNS names.
//
// DomainControllerName(NULL), DnsDomainName(NULL)
//
//      DsBind will attempt to find to a global catalog and fail if one
//      can not be found.
//
//      Mutual authentication will be performed using an SPN of
//      GC/DnsHostName/ForestName where DnsHostName and ForestName
//      represent the DomainControllerName and DnsForestName fields
//      respectively of the DOMAIN_CONTROLLER_INFO returned by the
//      DsGetDcName call used to find a global catalog.
//
// DomainControllerName(NULL), DnsDomainName(value)
//
//      DsBind will attempt to find a domain controller for the domain
//      identified by DnsDomainName and fail if one can not be found.
//
//      Mutual authentication will be performed using an SPN of
//      LDAP/DnsHostName/DnsDomainName where DnsDomainName is that
//      provided by the caller and DnsHostName is that returned by
//      DsGetDcName for the domain specified - provided DnsDomainName

Routine Description:

Constructs a Service Principal Name suitable to identify the desired server.
The service class and part of a dns hostname must be supplied.

This routine is a simplified wrapper to DsMakeSpn.
The ServiceName is made canonical by resolving through DNS.
Guid-based dns names are not supported.

NOTE:
This routine is no longer recommended for use. In order to be secure, an SPN
should be constructed purely on the client without reliance on other services,
such as DNS, which may be spoofed.

The simplified SPN constructed looks like this:

ServiceClass / ServiceName / ServiceName

The instance name portion (2nd position) is always defaulted.  The port and
referrer fields are not used.

Arguments:

    ServiceClass - Class of service, defined by the service, can be any
        string unique to the service

    ServiceName - dns hostname, fully qualified or not
       Stringized IP address is also resolved if necessary

    pcSpnLength - IN, maximum length of buffer, in chars
                  OUT, space utilized, in chars, including terminator

    pszSpn - Buffer, atleast of length *pcSpnLength

Routine Description:

Register Service Principal Names for a server application.

This routine does the following:
1. Enumerates a list of server SPNs using DsGetSpn and the provided class
2. Determines the domain of the current user context
3. Determines the DN of the current user context if not supplied
4. Locates a domain controller
5. Binds to the domain controller
6. Uses DsWriteAccountSpn to write the SPNs on the named object DN
7. Unbinds

Construct server SPNs for this service, and write them to the right object.

If the userObjectDn is specified, the SPN is written to that object.

Otherwise the Dn is defaulted, to the user object, then computer.

Now, bind to the DS, and register the name on the object for the
user this service is running as.  So, if we're running as local
system, we'll register it on the computer object itself.  If we're
running as a domain user, we'll add the SPN to the user's object.

Arguments:

    Operation - What should be done with the values: add, replace or delete
    ServiceClass - Unique string identifying service
    UserObjectDN - Optional, dn of object to write SPN to

Description

    This client call converts an RDN value into a quoted RDN value if
    the RDN value contains characters that require quotes. The resultant
    RDN can be submitted as part of a DN to the DS using various APIs
    such as LDAP.

    No quotes are added if none are needed. In this case, the
    output RDN value will be the same as the input RDN value.

    The RDN is quoted in accordance with the specification "Lightweight
    Directory Access Protocol (v3): UTF-8 String Representation of
    Distinguished Names", RFC 2253.

    The input and output RDN values are *NOT* NULL terminated.

    The changes made by this call can be undone by calling
    DsUnquoteRdnValue().

Arguments:

    cUnquotedRdnValueLength - The length of psUnquotedRdnValue in chars.

    psUnquotedRdnValue - Unquoted RDN value.

    pcQuotedRdnValueeLength - IN, maximum length of psQuotedRdnValue, in chars
                        OUT ERROR_SUCCESS, chars utilized in psQuotedRdnValue
                        OUT ERROR_BUFFER_OVERFLOW, chars needed in psQuotedRdnValue

    psQuotedRdnValue - The resultant and perhaps quoted RDN value

Return Value:
    ERROR_SUCCESS
        If quotes or escapes were needed, then psQuotedRdnValue contains
        the quoted, escaped version of psUnquotedRdnValue. Otherwise,
        psQuotedRdnValue contains a copy of psUnquotedRdnValue. In either
        case, pcQuotedRdnValueLength contains the space utilized, in chars.

    ERROR_BUFFER_OVERFLOW
        psQuotedRdnValueLength contains the space needed, in chars,
        to hold psQuotedRdnValue.

    ERROR_INVALID_PARAMETER
        Invalid parameter.

Description

    This client call converts a quoted RDN Value into an unquoted RDN
    Value. The resultant RDN value should *NOT* be submitted as part
    of a DN to the DS using various APIs such as LDAP.

    When psQuotedRdnValue is quoted:
        The leading and trailing quote are removed.

        Whitespace before the first quote is discarded.

        Whitespace trailing the last quote is discarded.

        Escapes are removed and the char following the escape is kept.

    The following actions are taken when psQuotedRdnValue is unquoted:

        Leading whitespace is discarded.

        Trailing whitespace is kept.

        Escaped non-special chars return an error.

        Unescaped special chars return an error.

        RDN values beginning with # (ignoring leading whitespace) are
        treated as a stringized BER value and converted accordingly.

        Escaped hex digits (\89) are converted into a binary byte (0x89).

        Escapes are removed from escaped special chars.

    The following actions are always taken:
        Escaped special chars are unescaped.

    The input and output RDN values are not NULL terminated.

Arguments:

    cQuotedRdnValueLength - The length of psQuotedRdnValue in chars.

    psQuotedRdnValue - RDN value that may be quoted and may be escaped.

    pcUnquotedRdnValueLength - IN, maximum length of psUnquotedRdnValue, in chars
                          OUT ERROR_SUCCESS, chars used in psUnquotedRdnValue
                          OUT ERROR_BUFFER_OVERFLOW, chars needed for psUnquotedRdnValue

    psUnquotedRdnValue - The resultant unquoted RDN value.

Return Value:
    ERROR_SUCCESS
        psUnquotedRdnValue contains the unquoted and unescaped version
        of psQuotedRdnValue. pcUnquotedRdnValueLength contains the space
        used, in chars.

    ERROR_BUFFER_OVERFLOW
        psUnquotedRdnValueLength contains the space needed, in chars,
        to hold psUnquotedRdnValue.

    )

Description

    This client call accepts a DN with quoted RDNs and returns the address
    and length, in chars, of the key and value for the first RDN in the DN.
    The RDN value returned is still quoted. Use DsUnquoteRdnValue to unquote
    the value for display.

    This client call also returns the address and length of the rest of the
    DN. A subsequent call using the returned DN address and length will
    return information about the next RDN.

    The following loop processes each RDN in pDN:
        ccDN = wcslen(pDN)
        while (ccDN) {
            error = DsGetRdn(&pDN,
                             &ccDN,
                             &pKey,
                             &ccKey,
                             &pVal,
                             &ccVal);
            if (error != ERROR_SUCCESS) {
                process error;
                return;
            }
            if (ccKey) {
                process pKey;
            }
            if (ccVal) {
                process pVal;
            }
        }

    For example, given the DN "cn=bob,dc=com", the first call to DsGetRdnW
    returns the addresses for ",dc=com", "cn", and "bob" with respective
    lengths of 7, 2, and 3. A subsequent call with ",dc=com" returns "",
    "dc", and "com" with respective lengths 0, 2, and 3.

Return Value:
    ERROR_SUCCESS
        If *pccDN is not 0, then *ppDN points to the rest of the DN following
        the first RDN. If *pccDN is 0, then *ppDN is undefined.

        If *pccKey is not 0, then *ppKey points to the first key in DN. If

DsIsMangledRdnValueW(
    LPCWSTR pszRdn,
    DWORD cRdn,
    DS_MANGLE_FOR eDsMangleForDesired
    );

Description

    Determine if the given RDN Value is mangled, and of the given type. Note that
    the key portion of an RDN should not be supplied.

    The name may be quoted or unquoted.  This routine tries to unquote the value.  If
    the unquote operation fails, the routine proceeds to attempt the unmangle.

    A change was made in the default quoting behavior of DNs returned from the DS
    between Windows 2000 and Windows XP. This routine transparently handles RDNs with
    special characters in either form.

    The routine expects the value part of the RDN.

    If you have full DN, use DsIsMangledDn() below.

    To check for deleted name:
        DsIsMangledRdnValueW( rdn, rdnlen, DS_MANGLE_OBJECT_FOR_DELETION )
    To check for a conflicted name:
        DsIsMangledRdnValueW( rdn, rdnlen, DS_MANGLE_OBJECT_FOR_NAME_CONFLICT )

Arguments:

    pszRdn (IN) - RDN value character string. Termination is not required and
        is ignored.

    cRdn (IN) - Length of RDN value in characters excluding termination

    eDsMangleForDesired (IN) - Type of mangling to check for

Return Value:

    BOOL - True if the Rdn is mangled and is of the required type

    );

Description

    Determine if the first RDN in a quoted DN is a mangled name of given type.

    The DN must be suitable for input to DsGetRdn().

    To check for deleted name:
        DsIsMangledDnW( dn, DS_MANGLE_OBJECT_FOR_DELETION )
    To check for a conflicted name:
        DsIsMangledDnW( Dn, DS_MANGLE_OBJECT_FOR_NAME_CONFLICT )

Arguments:

    pszDn (IN) - Quoted Distinguished Name as returned by DS functions

    eDsMangleFor (IN) - Type of mangling to check for

Return Value:

    BOOL - True if first RDN is mangled and is of the given mangle type
