Someone Actually Thought This Through

Introduction

I wrote a rant on the "sa" password a couple weeks ago and got quite a bit of feedback. One

of the items was a response from Great Plains Software, which was mentioned in the article as

having poorly designed their software to use the "sa" account. What follows is the response that I

was sent from Ross Hillier at Great Plains.

Great Plains Explanation of It's Use of the "sa" Account

Thank you for your efforts to make our Dynamics and Enterprise products

better.  However, I do believe that your criticisms are founded on some

incorrect information.  I would like to take an opportunity to correct this

inaccuracy.  If this information was incorrectly communicated to you by

other members of our Great Plains' team, then I would like to apologize on

their behalf.

Great Plains has two products which utilize Microsoft SQL Server:  Great

Plains Dynamics for SQL Server and Great Plains eEnterprise.  Contrary to

your assertion, neither of these products requires access to the sa login

for adding users to the accounting system.  (Note the usage of "requires".

Both of our products have the option of using the sa account to simplify the

process of adding users, but neither product "requires" usage of sa).

Great Plains has over five thousand businesses using our two SQL Server

based products.  As you might imagine, these customers have a vast range of

skills.  Some of these users are sophisticated and knowledgeable experts on

SQL Server like yourself.  However, some of our customers' knowledge is

focused more along accounting lines, and sometimes their detailed knowledge

of SQL Server is not at your level.

To meet the needs of all our customers, we actually support two methods for

adding users to the system.  One method is targeted at sophisticated users

like yourself (which does not require use of the sa account), and the other

method is targeted at less SQL Server-savvy users.  This second method does

utilize the sa account.

Use of the System Administrator account.

----------------------------------------

The two methods for adding users are controlled using the "SQL Options"

window which is located under the "System Setup" menu in Dynamics or

eEnterprise.  The SQL Options window has two checkboxes which control

whether Dynamics or eEnterprise should automatically add server logins and

database users to the backend.

For those customers who have a more advanced knowledge of SQL Server, they

have the option of "unchecking" these two options within eEnterprise setup.

When these options are unchecked the process of adding users is now a

two-step process:

1) The SQL DBA adds the new login and grants SQL permissions.

2) The Accounting administrator (or end-user) simply adds the same user

within the accounting application and not SQL Server.

This method does not require the Dynamics or eEnterprise user to have access

to the sa account.

For less sophisticated users (who may not even have a DBA), we recommend

leaving the two setup options "checked".  When the setup options are

checked, Dynamics and eEnterprise will automatically add the necessary users

and logins to SQL Server when a new user is created inside the accounting

system.  While this method does require that the accounting administrator

have access to the sa account, our user feedback indicates that this a more

popular choice for our smaller and less sophisticated users than the

alternative two-step process.  For our smaller users, the "DBA" and the

"Accounting Administrator" are almost always the same person.  In that case,

access to the sa account is not an issue.

By using the sa account, we can get closer to the goal of eliminating the

need of having a user to touch the SQL back end during the installation and

configuration process. Other than installation and configuration, there are

no other processes within the system that require the sa account.

Dedicated SQL Server.

----------------------------------------

Again, Great Plains has thousands of customers using our SQL Server

products, and these customers have a huge range of needs and expertise.

When purchasing a new back office product like Dynamics or eEnterprise, many

of these customers lack the in-depth SQL Server experience to properly

predict the hardware needs for their system.  Back office systems are

critical "Line of Business" applications.  Customers can't afford to have

their business compromised by an inability to pay bills or produce the

payroll in a timely fashion because of inadequate or overloaded hardware.

With this in mind, our general corporate recommendation is to load our

product in a dedicated server.  We feel this best protects our customer's

vital need to have a stable and high performing line of business

application.  It would be foolish for Great Plains to imply that it's OK in

all cases to load any number of other applications and utilize the same SQL

Server and computer infrastructure that is in place to maintain critical

financial business information.

Of course, our recommendation to use a dedicated server is simply our

blanket starting point of reference for customers.  There are cases where

customers have the technical background and skills to properly predict

loading on their system using tools like performance monitor or SQL

profiler.  These customers can then make their own informed decision to

configure their hardware in any fashion they desire.  However, we still

believe our customers interests are best served by starting with a more

conservative position and consolidating only after a thoughtful and thorough

analysis has been performed.

Enterprise Manager, Query Analyzer or any administrative interface with SQL

Server.

----------------------------------------

These tools are designed for use by administrative personnel. There are no

requirements for day-to-day use of Great Plains Dynamics for SQL Server or

Great Plains eEnterprise to use these tools. It is not necessary to give any

of these tools to "anyone that is not trusted and knowledgeable about SQL

Server".

Thanks,

Ross

I happen to like this approach for software development. I just wish that this

information was more widely disseminated to Great Plains technical support and VARs. Given this response

I am confident that Great Plains will see this gets done. My opinion of this approach

to using the "sa" account is valid since in many cases, there will be no DBA in smaller

companies that use this software.

As far as the dedicated server section. I understand the position taken and it does make sense. Given the

option of using "sa", this is fine with me. If there is no option, then I think it is rather short-sighted

of any software company to deliver a SQL Server solution without considering that another application may

reside on the same server.
