Routine Description:

    RxpSessionMatches is used to determine whether or not a given session
    structure (part of an array, probably) matches the given client name
    and user name.

Arguments:

    Candidate - possible match in the form of a superset info structure.

    UncClientName - an optional UNC computer name.

    UserName - an optional user name.

Return Value:

    BOOL - TRUE if structure matches client name and user name.
