SQL Server Authentication Not Working
Oct 24, 2002
I have setup ODBC to connect to a SQL Server 200 database (evaluation version) so I can link tables into an Access database. In the ODBC setup, I selected SQL Server Authentication versus Windows Authentication. However, when I link a table into Access it still uses Windows Authentication first.
I found an article here that discusses the issue:
http://support.microsoft.com/default.aspx?scid=kb;en-us;Q279526
It suggested that I run an MDAC update to version 2.6. So I did that and I still have the same problem.
I tried to link a table through some code in Access by changing the connect string to "Trusted_Connection=No" but it still linked up with "Trusted_Connection=Yes".
So how do I use SQL Server Authentication only?

Hi,
We just restored our database from SQL Server 2000 to SQL Server 2005 for me to test things out. Right off the bat I started seeing errors where I could not select data from a table. I would get the "Invalid object" error unless I specified the schema of the object. I found this confusing because I was connected to the server using SQL Server Authentication as the schema_owner ( i.e user name and schema name were identical). I thought this was due to the fact that my DEFAULT_SCHEMA was not set but when I checked, user 'testuser' had schema 'testuser' as default_schema. I also made sure I was connected to the Database using SQL Server Authentication as user 'testuser'.
But the following would fail:
SELECT * FROM Employees
The following would however succeed.
SELECT * FROM TestUSer.Employees
I was really confused and when I read some posts and forums, I decided to check SYSTEM_USER and to my dismay, it returned my Domain login as the value as opposed to "TestUser". I re-connected using my Domain Account and SYSTEM_USER returned the Domaim Login as expected but when I switched to Sql Server Authentication and connected as user "testuser", SYSTEM_USER would still return my Domain Account. I believe this is the source of my problems. Can you tell me what's going on.?
I am a member of the sysadmins group and CURRENT_USER returns DBO. Please help as this is driving me nuts!
Thanks

Hey there,
I have a table [user] in a SQLExpress database [Database.mdf] in the App_Data folder. There are two columns. [userId] and [password]. I want to authenticate the user who wants to log in through a Login control. the user should have his userId and password in the [user] table. I digged and made my code. but it doesn't work it keeps giving me that the user is not authenticated. i guess it has no errors. please tell me if you find the error. here is the code: 1 protected void Login1_Authenticate(object sender, AuthenticateEventArgs e)
2 {
3 SqlConnection conExpress = new SqlConnection("Data Source=.\SQLEXPRESS;Initial Catalog=Database;Integrated Security=True;User Instance=False"); //Create the server connection
4
5 try
6 {
7 string id_user = Login1.UserName.Trim(); //Get the username from the control
8 string pass_user = Login1.Password; //get the Password from the control
9
10 //These are a sql and connection Examples
11 string sql = "SELECT userId, password FROM user WHERE userId = @param_Id AND password = @param_Password";
12 SqlCommand comSQL = new SqlCommand(sql, conExpress); //Create the sql command using sql string and sql connection
13
14 //Add the sql parameters
15 comSQL.Parameters.AddWithValue("@param_Id", id_user); //New on VS 2.0
16 comSQL.Parameters.AddWithValue("@param_Password", pass_user);
17
18 string cod_user = "";
19 string name_user = "";
20
21 //Open database connection
22 conExpress.Open();
23 SqlDataReader dr = comSQL.ExecuteReader();
24 while (dr.Read())
25 {
26 cod_user = dr.GetValue(0).ToString(); //The coduser is unique onto database table
27 name_user = dr.GetValue(1).ToString();
28 }
29 conExpress.Close();//Close Database Connection
30 if (cod_user != "") //The user exist onto database
31 {
32 //Create the session vars
33 Session["coduser"] = cod_user;
34 Session["nameuser"] = name_user;
35 e.Authenticated = true; //Grant the access, Goes to DestinationPageUrl
36 }
37 }
38 catch(Exception)//On Login Error
39 {
40 e.Authenticated = false;//Confirm that you are out
41 conExpress.Close();//On any error case, close the database connection
42 }

This is for SQL Server 2005
When logged onto a server and connecting using windows authentication (either by server name or localhost) I am getting in fine, but when I connect using the IP I get the following error.
I can log in using SQL Server authentication with the IP.

This morning I attempted to connect to my local copy of SQL Server (2012) (Win 7) using Windows Authentication. I was unable to do so and per the error log it was due to error 18456 (invalid credentials).
Yesterday I changed my windows password. Is it possible for this to be the cause?
FYI, following is from the error logs:

This is an informational message only. No user action is required.
The logs showed the error occurred yesterday (4/28) which is about when I changed my password. The 17:09 log (last one) is when I shut down my computer. Note that I was logged into SQL Server when I changed my Windows password and worked with it several times through out the day.
Also, per the configuration manager SQL Server (MSSQLSERVER) (and all other services) is stopped and I was unable to start it ("The request failed or the service did not respond in a timely fashion).

Hi.
I wonder if it is possible to set forms authentication for report manager but leave report server "as it is". I need to authenticate users from external LDAP and can't use windows authentication for report manager, but I would also like to leave report server open for anonymous users. In that way authenticated administrators could create reports which anonymous users could read.
I tested the Security Extension Sample and got it working when I rewrote the authentication part with my own LDAP authentication.
If I have understood correctly, the report manager is just application inside report server so is it possible to use forms authentication with one application but still leave the report server with Windows authentication?

Hi,
I need to figure out what kind of Authentication , I need to use for following applicaiton
Product : -
1 ) It resides on a its Domain and has access to Database on that Domain.
2 ) We have a application level login , n based on application login id
display specific pages.
The question that bother me is this
Q ) If i use NT authentication , then a user will be required to
a ) Login to domain (with userid and password) first and then
b ) Then i would require to again login to applicaiton with application
level login and password.(different levels of login as there)
Based on the application level login i will display only specific
asp pages. They have different access rights..and roles.
Requirment is to login only once..and it should authenticate to application display specific pages and authenticate to SQl server database also..
Is there any way thru which i can map my application level login to SQl server.. and what authentication should i use..
Thanks,
Teny

Hello,
(Using win2k, sqlserver2k, framework 1.1)
I have an fairly data-heavy application that uses Windows authentication (Trusted connection/aspnet account) to connect to Sql Server. The site uses IIS basic authentication.
On the dev server everything works fine but when I move to the live server things get strange and it starts to crawl along. (Pages load OK but then it just crawls as it loads the datagrids etc. Sometimes it brings back incomplete/incorrect data )
BUT When I use Sql Authentication to connect to Sql Server and there is no problem at all!
Ok, there is something obviously wrong with the live server (which is identical setup to dev)but I dont know where to start.
Any ideas??

Hi all,
I've got two applications which both have a database on my MS SQL 2000 server. The problem is, one application must use Windows Integrated Authentication (which it is currently using and cannot be changed) whilst the other application which I'm trying to configure must use a SQL password.
Since the server has already been configured to use Windows Integrated Authentication for the existing database and application, how do I configure the other database to use the SQL password?
Thanks.

Hi all,
My work is using a shared application
which accesses a MSSQL 2000 database. To access the application, the
folder on the Windows 2003 Server is shared and users can access the
folder through a shared drive.
For the application to access the
database, it uses an ODBC connection to the MSSQL server which
originally used the SA password.
We have recently switched to using
Windows Integrated Authentication because we believe it offers a
higher level of security. However the only way in which we have been
able to enable this is to add the windows users to the SQL server.
The problem with this is that the
application sets permissions for individual users on what records
they can see within the database. We have found that by adding the
windows users to the SQL Server, they can bypass the permissions the
set by the application by simply using any application that can use
an ODBC connection, such as Enterprise Manager, and see all the
database.
One way around this would be to set up
domains of users with access privileges to the tables which reflect
the permissions set by the application, and configuring a view of the
data so they may only see the records that they have permissions to.
However to do this would require a high administrative cost to ensure
that changes made in the application are reflected in the privileges
of the SQL server.
Instead, is there a way the SQL server
can authenticate that the ODBC connection is coming from the correct
application using Windows Integrated Authentication?
This would allow the applcation to
determine security, and stop users from connecting to the SQL server
using other applications.
Alternatively, can the SQL server,
using Windows Integrated Authentication, also ask the application to
supply a username and password?
Any help with this matter would be
greatly appreciated.
Thanks!

Hi,
Say, I have configured my SQL to use Mixed Authentication. Now, I have a applicaiton which uses my SQL Server. The application just creates a database in SQL Server and uses the database to store its information.
This application also has a SYSTEM DSN under ODBC through which it accesses the database. For the application to access this database, should I only use SA (as my SQL instance is configured to use Mixed Authentication) or can I use Windows Authentcation too...
If I should only use SA, do we have a documentation which talks about this.
Thanks

The computer has to be as a workgroup machine to reflect our live server.
The user LMSEndPointUsers is a SQL Server Login
The user ostc-dev-001endPointUsers is a machine login
We have employed the Security class as per the information given in the SQL Server documentation with the intention of using the WS-Security headers that apparently are to be used when trying to authenticate using a SQL Server login.
----------------------------------------------------------------------------------------------------------------
Code used to connect and try and reciev the dataset.
string sUserName = "userName";
string sPassword = "Password";
LMS_Endpoint.OSTC_LMS_Endpoint wsSQLTester = new LMS_Endpoint.OSTC_LMS_Endpoint();
SqlSoapHeader.Security sqlSec = new SqlSoapHeader.Security();
sqlSec.Username = sUserName;
sqlSec.Password = sPassword;
XmlWriter writer = XmlWriter.Create("Security.xml");
writer.WriteStartElement("security");
sqlSec.WriteXml(writer);
wsSQLTester.sqlSecurity = sqlSec;
DataSet dsMySet = wsSQLTester.ostc_SQLSoapTester("RH6915145507");

Hi,
I have 7.0 server running with sp2 on NT box sp 5. This Sql server is configured to take both sql and NT authentication. Somehow, the bridge between NT and SQL server doesn't seem to be working as sql server does not recognize any NT authentication. Is there any way to fix it?
Because of this problem, I am unable to schedule any DTS package as sql server security doesn't recognize the sqlagent startup account and gives a login failure error.
I am about to open a ticket with Microsoft but before that if anybody can suggest me anything..

I have an SQL Server (2000 Edition) that does not belong to a domain; Server A. (It loggs onto its own computer domain). From this server I would like to add another sql server registration through Enterprise Manager that does belong to a domain; Server B (also 2000 Edition).
The only way I can register Server B on the Server A computer is by logging onto the domain that Server B belongs to.
Is it possible to just use SQL Server authentication and not have Server A logon to the Server B domain? If so what could I be doing wrong?
When Server A is logged onto its own local computer domain I can ping Server B and also resolve the server by name.
Any suggestions?
Many Thanks,

I am trying to setup cached reports so that one of my larger reports doesn't have to be re-run every time someone wants to view it (the data source only updates every 24 hours).
Anyway I made a new data source, set the report to use that, and in that data source I said to use "SQLexampleUserName" as the stored credentials.
Now when I go to run the report it says: Login failed for user 'username'. The user is not associated with a trusted SQL Server connection.
This is referenced in the MSKB here:
http://support.microsoft.com/default.aspx/kb/555332
Which makes sense, but now my question is: If I want to used a cached report do I HAVE to allow SQL Server Credentials?
I was using Windows Authentication only up to this point.

Viual Studio 2003; ASP.Net; .Net Framework 1.1, SQL Server 2000Hi,We have two domains in our network - prod.domain.com and dev.domain.com. There is no trust relationship between the two domains. I am trying to connect to an SQL Server in dev.domain.com using SQL Server Authentication from prod.domain.com. My connection string uses the fully qualified domain name (xxxxxx.dev.domain.com) to connect. The error I receive is SQL Server does not exist or access denied. I can access the database through SQL Query Analyser and SQL Enterprise Manager across the domains with no problems. I can also connect through a .udl file using the same SQL Server Authentication information.If I run my application from dev.domain.com accessing a database that sits in prod.domain.com then the connection is fine.Can someone point me in the direction of any areas I can troubleshoot to see what is preventing the connection please? The only things I can see on the web are details of windows authentication across domains which isn't relevant to me in this instance. I've been pulling what little hair I have out over this for the last week.Thanks in advance.
