Setup Of Security / Integrated Win Security On Vista

Jul 6, 2007

I have Sql Server Express installed on Vista (service pack 2)

I have Visual Studio 2005 with an application that I'm trying to access it with within a WCF service.



The login ID of the service is added to the database.

The database has remote access turned on.

The ID is granted access to all databases within the server.

The thread is being set with WindowsProvider and the services set their thread to WindowsProvider.

The dataserver is set with using Windows Authentication for security.



When I open my connection to the database, though, it reports the typically useless message that the connection is not allowed and that the server may not allow remote connections.



How to I get past this? I've done everything right.

Jdbc Integrated Security With The Sql Database On Windows Vista X64 Bit

Mar 17, 2007

I am trying to connect to an SQL database with a Java program compiled in NetBeans IDE. I have copied the proper .dll in the auth folder to the same folder as the .jar file required. I have tried a lot of things for a lot of hours, and am still coming up with the message "Driver is not configured for integrated security and "could not load the xxxxx.dll

Has anyone come up with a solution or a workaround to this problem. Please help. I have read the documentation until I am blue in the face. Please only respond if you have a 64 bit machine.



Thanks, Frank

Integrated Security...

Oct 3, 2005

  Does anyone know how to impersonate a user and then use integrated security with SQL server?  Every place I've looked so far only shows how to use integrated security through IIS.  For some reason, everytime I impersonate a user account, SQL server identifies me as "NT AUTHORITYANONYMOUS LOGON"  Is this by design? or am I doing something wrong?

Windows Integrated Security With SQL Server

Apr 29, 2005

In my architecture I have a Domain Controller with Active Directory (DOMAIN_A), IIS 6.0 (WEBSERVER) and SqlServer 2000
(SQLDBSERVER).



The WEBSERVER has a
.NET application with windows authentication.  The .NET application interacts with the
database server. I want to use Integrated Security to pass in
the users login credentials to the database to run any database calls so that I can
audit who is making what calls on the database.

The connection string
I am using for this is as follows:


 string connStr =
"Server=SQLDBSERVER;Database=xxx;integrated
security=SSPI";


The problem arises
after I login to the web application (I use the user DOMAIN_ASomeUser where
SomeUser is a user who has permissions set up to make all of the database
calls). After logging in however, when I go to a page that makes a database
call I get the following error:


 System.Data.SqlClient.SqlException: Login failed for user
'DOMAIN_AWEBSERVER$'.
It seems that for some
reason, .NET is not passing the login name SomeUser, but instead is passing
SERVERNAME$. Would anyone pls have any ideas how I can implement this. Any guide or references would be much appreciated.

Thanks in advance.

Clustering And Sql Server Integrated Security

Dec 17, 1998

We are using a VB application with a "dsnless" connection. It is not able to connect to the SQL box using integrated WinNT authentication. Receive the below error message:

Run-time error '-2147217843 (80040e4d)':
[Microsoft][ODBC SQL Server Driver][SQL Server] Login Failed

We can connect to our test SQL box with using the same application with no problem. The only difference we can see is the clustering on the "real" box.

We are using the following program string to connect to both boxes with the exception of the server we connect to:

"driver={SQL Server};server=server;uid=;pwd=;database=pubs"

Any info. would be greatly appreciated!

Thanks :)

Integrated Security / Domain Name Problem

Nov 10, 1998

We've encountered a problem on one of our SQL servers running integrated security where MS Security Manager errors out with "An error occured executing sp_addlogin using Domain_nameusername - " is not a valid name since itbegins with an invalid character." We think it is because the domain has the underscore character in it name. Can anyone confirm or point to other possible configuration issues?

Limiting Integrated Security Connections?

Jul 26, 2007

Ideally, I'd like to move away from using SQL-based logins for our internal applications and take advantage of integrated security instead.

Defining AD groups and their permissions in SQL is simple and getting the application to work with that is not an issue.

Where I'm having difficulty, though, is in isolating the accessibility in integrated security. Because the SQL-based login was isolated from the windows user, they could only get access to the sql server via our app -- their normal windows accounts had no access.

If we switch to use only windows authentication, the user would be able connect fine from our application and have rights to various tables. The issue is that they could also connect via Enterprise Manager, Excel, or any other tool. Is there any way to limit the exposure so that we can take use of AD for our access but further limit to allow connections based upon the application? I realize that this could be impersonated, but it's still better than nothing...

Application Login And Integrated Security

Aug 8, 2007

Hello,

We're having a bit of a problem getting Integrated Security to work with a .Net 2.0 application and SQL 2005. While we're tweaking permissions on the SQL-side, we came across an account "Application Login" and wondered what its role is. First, our problem:

Currently, the users in the AD group get a connection error. This group is defined as follows at the instance level:

role: public
user mapping: to the database without any default schema
securables: none
status: grant and enabled

At the database security level:

general: none
securables: execute on all (100+) stored procedures

And we gave them "Execute" on the database itself.

A little background: we had detached and copied this database from one server to another. So we suspect that the Application Login may have been modified/corrupted, even though it appears to be identical between the original and the copied databases. So we redefined it on the copied DB to match the original.
Another group, which is defined as dbo on the database, has no problem at all connecting and running the application.

The Application Login has Execute permissions on all stored procedures and Delete, Insert, Select, Update, and View Definition on the ChangeLog table. It also has db_DataReader, db_DataWriter, and db_ddlAdmin roles associated with it.

Is there another SQL login required for initial connection to the database even though Integrated Security=SSPI is used in the connection string?

Does anyone see where we may be missing a security setting for the non-dbo user group to connect to the database?

Thanks very much for any suggestions, ideas ....
Cheers,
Tess

Restrict ASP.NET App DB Permissions Using Integrated Security

Mar 6, 2007

How might I Restrict ASP.NET app DB permissions using Integrated Security?

I can see how it's done with SQL Authentication, but I'd prefer to do it with Windows Authentication.

Is it a matter of restricting the permissions of the general ASP.NET user (€śNT AUTHORITYNETWORK SERVICE€?)...seems like it might affect too much.

Or can I have a Windows user/identity/account that is specific to a single ASP.NET Application?

Any guidance on this would be appreciated.

Thanks!

Windows Integrated Security And Subscription

Dec 17, 2006

Hi,

I am having a problem in applying subscription to a report.

Here is my case:

I have a datasource with 'Windows integrated security ' authentication, yes....I am using windows domain authentication, so login info is not stored in DB but its authenticated from domain. Now the report I want to use subscription on is using this DS. I read it somwehere that I can use rsconfig -e -u -p option to assign user to unattended reports.

I think, this is the unattended report. I tried with rsconfig and then clicked on 'new subscription option'...and i got error (again) saying 'Subscription can not be created because the credentials used to run the report are not stored...or if linked report.....blah blah...'

I want to use subscription to this report but with 'Windows integrated security', is there any way I can do it ?? How can I assign some user to this report without changing authentiation method and use subscription ?

Help me ...I am stuck, this is the last milestone in my project !!!

Thanks,

Prashant

Subscriptions And Windows Integrated Security

Mar 1, 2007

I have a set of reports that read from an Analysis Services cube. Permissions are managed at the cube level since different users should look at the same report but different data. This is why for those reports, the data source has Windows Integrated Security set.

Those same users should be able to subscribe to those reports, the problem is that for subscriptions to work, the data sources must store the credentials. This means the filtered reports are lost since the stored account will show all the reports for all users.

Is there any way of generating "filtered subscriptions"?

Thanks in advance

Integrated Security && Database Design

Nov 27, 2007

I'm looking for a best practices document or microsoft book that explains proper database security design for applications accessing sql using integrated security.

I am an application developer at a shop that has been using sql authentication to connect to sql servers.
We have an sql login and user setup for each application. This sql user has read/write access to that applications database. The (human) users have no idea what the login is, we have a special generic dll that feeds the sql logins and passwords to our applications at run time for each app.
Operations is pushing to move out of mixed mode and into full integraded security mode. Microsoft best practices push integrated security so I understand the move. What I'm trying to locate is some microsoft documentation on security design.

This is what I have pieced together so far regarding the windows authenciated approach to applications accessing databases. With windows security, users will be able to bypass our applications all together and use tools like access and excel to hit the databases even if we don't want them going in there. Their windows security will allow them to do this with integrated security. This is assuming we don't have the app "run as windows user x" and that we grant the user groups permissions on the database objects. This means instead of granting user groups generic read/write on the entire database like we could with sql security we need to consider what groups use the application and consider what permissions need to exist on each database object for that group. In addition we will need to almost exclusively use views and stored procedures to get data as these will act as filters to only allow users to touch what they should be allowed to touch. Having select and update statements within apps would require users have table rights, which is basically the same as allowing them to do anything. Each view and procedure will need to be set up with special consideration so that if a user where to hit them directly we would be ok with it...Basically the application layer which contains a multitude of validation logic on user entry controls can be skipped by a "smart" user who decides to "fool around" in access"

. A solution to fix this would be to have our apps run as a special windows user id but operations has refused to allow this. And honestly this would be nearly identical to just using sql authentication. We are looking at a security redesign of over 60 systems and a multitude of reports. I'm looking for a best practices document or microsoft book that I can use to help demonstrate the amount of redesign work making this move will require and shed more light on how this all works.

I have already looked at the following security documents which do not have what I am looking for, so i figured I better ask.

Sqlconnection.open Slow With Integrated Security

My enviornment is as follows:

Sql Connection Fails With Integrated Security=SSPI

Apr 9, 2008

I am using windows impersonation in a CLR that is retrieving folder structure. In order to use impersonation I need to pass the windows credential to the SQL server so I am trying to use "integrated security=SSPI" and I also tried "integrated security=true" as well with the same result...I get the error: Login failed for user ''. The user is not associated with a trusted SQL Server connection.
The SQL Server and IIS are located in different un-trusted domain. I am however able to connect to the SQL Server using user id and password. In my web.config file:
<add name="ConnectionName1" connectionString="Data Source=IpAddress,Port#;Initial Catalog=DatabaseName;Integrated Security=true;persist security info=False; Trusted_Connection=Yes;" providerName="System.Data.SqlClient"/> à Doesn’t work
<add name="ConnectionName2" connectionString="Data Source=IpAddress,Port#;Initial Catalog=DatabaseName;uid=user;pwd=password;" providerName="System.Data.SqlClient"/> Ă WorksBased on the error message it looks like there is no user passed to the SQL server.
What am I missing? At this point I am thankful for any input…

SqlConnection WITHOUT Integrated Security - Login Failed

Mar 30, 2005

Any idea why I cannot connect to a SQL Server database using SqlConnection and no Integrated security?  I get a "Login failed for user 'XXXX'" error.  The user ID and password I am using are all correct and have the required access (tested several times from different places).The connection string I am using is:
"Server=XXXXX;Database=XXXXX;Trusted_Connection=fal  se;User ID=XXXX;Password=XXXXX"
I have also tried replacing "Server" by "Data source", "Database" by "Initial catalog", "Trusted_Connection" by "Integrated security", "User ID" by "UID" and "Password" by "PWD".Any ideas?
 
Thanks in advance!

Utterly Confused About SQL Login Vs. Integrated Security

Dec 16, 2005

I 'm a newbie to SQL Server, been using Access as a database for my web app. and have decided I need the power of SQL Server. Using VWD Express, I am able to generate a SQL database with my tables and stored procedures quite easily as well as access the database from my asp.net code. This works fine on my devlopment machine. But now I want to deploy on my remote server and the webhost says they can attach my SQL database but they need my SQL login info. So I have a couple of questions:
1. Does the SQL database I create in VWD express only work in Integrated Security mode or can I assign a username & password to the .mdf file so I can upload to my remote host to work in a shared SQL environment?
2. Or am I confused and the .mdf file is just a data file which can be attached to any SQL account and the SQL login info only pertains to the instance of SQL Server that I'm trying to connect to?
3. My web host mainly uses SQL Server 2000. Will a simple database created in SQL Server 2005 Express work on an instance of SQL Server 2000?
If I can just figure these simple items out, I will be ecstatic!

Windows Integrated Security And Report Server

May 30, 2007

Greetings Folks,

We have a SQL Server Reporting Services instance running SP2. I have attempted to add a domain group in a trusted domain to the server to enable regular users to access reports. I have added this group to the instance folder as a SYSTEM USER and home as BROWSER. I am allowing those settings to be inherited down through the folders (reports and data sources) to the reports. My test user in this report receives:

The permissions granted to user 'DOMAINuser' are insufficient for performing this operation.
(log shows HTTP 500)

when the user attempts to use the URL to go directly to the report. If we try to navigate from HOME and walk the folders the user sees a blank HOME page.

I have used other groups with no problem.

Is there something I am missing in setting up the security environment? Any help would be greatly appreciated.

Thanks, Mark

Integrated Security From Non-domain Windows 2008

Oct 23, 2007

I am trying to connect as follows:

Server: Windows 2003, SQL 2005, on a domain
Client: Windows 2008 Beta, not on any domain

I created an account with the same user name as the domain user on the client machine. And then I logged in as that user and went to Manage Network Password. I entered the correct domain credentials. Verified that this worked for file shares. However, SQL does not appear to be recognizing this and it tells me:

Login failed for user ''. The user is not associated with a trusted SQL Server connection.


I have verified that this domain account is working properly with SQL when the client is also on the domain.

How can I get this Windows authentication scenario to work where the client is not on the domain and the SQL server is on the domain?

Using Integrated Security From .Net Web To Access SQL Server 2005

Oct 19, 2007



If I am posting to the wrong forum, please point me in the right direction.
We have upgraded to SQL Server 2005 and Window 2003 from SQL Server 2000 and Windows 2000, and have been having all kinds of problems with security of our web applications. We have been forced to put the system account of the web server as a user in the database in order for the web applications to work. We have lost the ability to control security at the user/role level. Is this the way security is going to work in Windows 2003/SQL Server 2005? How do I use integrated security so that I can secure web pages and database objects?
Thanks

But how can i say, in the definition of a linked server (at the remote machines) to swicth security system ?

If it is possible i could enter a fixed domain-account in that users fields, but i suppose that this field was intended for SqlServer security.
