Module Name:

    dbinstal.c

Abstract:

    LSA Protected Subsystem - Database Installation.

    This module contains code which will create an initial LSA Database
    if none exists.  Temporarily, this code is executed from within
    LSA Initialization.  This code will form part of the Security
    Installation applet when implemented.

    WARNING!  THE CODE IN THIS MODULE IS TEMPORARY.  IT WILL BE REPLACED
    BY SYSTEM INSTALLATION FUNCTIONALITY.

Author:

    Scott Birrell       (ScottBi)       August 2, 1991

Environment:

    User mode - Does not depend on Windows.

Routine Description:

    This function installs an initial LSA Database.  Any existing database
    will be reset to have its initial attributes.

Arguments:

    Pass - Either 1 or 2.  During pass 1 all information that is
        not product type-specific is initialized.  In pass 2,
        the product type-specific stuff is initialized.

Return Value:

Routine Description:

    This routine obtains configuration information from the registry.

Arguments:

    KeyHandle - handle to registry key node containing value.

    Name - The name of a value under the specifed key node.

    Value - Fills in the string with the value of the parameter.  The
        returned string is zero terminated.  The buffer is allocated in
        Process Heap and should be deallocated by the caller.

Return Value:

    STATUS_SUCCESS - If the operation was successful.

    STATUS_NO_MEMORY - There wasn't enough memory to allocate a buffer
        to contain the returned information.

    STATUS_OBJECT_NAME_NOT_FOUND - The specifed section or the specified

Routine Description:

    This routine is used to isolate the next token in a registry value.

    The token is returned in a single heap buffer containing both the
    STRING and the Buffer of that string containing the token.  The
    caller of this routine is responsible for deallocating the buffer
    when it is no longer needed.

    The string, although counted, will also be null terminated.

Arguments:

    Value - Supplies the value line being parsed.

    ParseContext - Is a pointer to a context state value.
        The first time this routine is called for a particular
        Value line, the value pointed to should be zero.  Thereafter,
        the value returned from the previous call should be passed.

    ReturnString - Returns a pointer to the allocated string.


Return Value:

    STATUS_SUCCESS - indicates the next token has been isolated.

    STATUS_INVALID_PARAMTER_1 - Indicates there were no more tokens in
            the Value line.

    STATUS_NO_MEMORY - memory could not be allocated for the token.

    This routine must establish values for the AccountDomain and

    attributes must be configured as follows:

    I.   Standalone Win-NT product

            AccountDomainName = "Account"

            PrimaryDomainName = Name of domain to use for browsing
                                (this is optional in this case)
            PrimaryDomainSid  = (None)

    II.  Non-Standalone Win-NT product

            AccountDomainSid  = (value assigned by user)
            PrimaryDomainName = (Primary domain's name)
