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

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

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

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,
I am trying to access the SQL server using windows authentication but its not working. But others can work on their windows authentication for the same server. Anything needs to be done from my end. Please explain.
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

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:

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).
I folks.I Have installed sql server 2005 express and choosed windowsauthentication on instalation, but i make a mistake and now i needmixed authentication, how can i modify this whithout uninstall andinstall again the application?thanks for the help.

View 1 Replies View RelatedHello,
(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,I'm using SQL Server 2005. My Connection String looks like that at the moment: <add name="LocalSqlServer" connectionString="Data Source=xx;Initial Catalog=xx;Persist Security Info=True;User ID=xx;Password=xx" providerName="System.Data.SqlClient"/> Now I'd like to change this kind of authentication to Integrated Windows AuthenticationI added the WorkerProcess IIS_WPG to the permitted Users but it didn't help.Changed the Connection String to this:connectionString="Server=xx;Database=xx;Trusted_Connection=True;"All I'm getting is that my NetworkService is not permitted to access DB when I try to connect to the DB in ASP.NET.How can I properly configure that? Thanks!

Would anyone please help me out here. which of the 2 modes of authentication is better and why??
View 3 Replies View RelatedHi,
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

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
I am in the process of rolling out a sql server 2005 enterprise install and had a question regarding authentication. We will be providing sql hosting for a number of groups on our campus, many who are not using our campus-wide active directory, though they all have an AD account.
Windows authentication via the management studio appears to use your AD authentication tokens and will not allow them to enter a username/password combo. Is there any way to configure this?
I would like to use our campus AD for obvious reasons but if there is a requirement for passing tokens this isn't going to work right? It's also going to make database mirroring more of a challenge.
Thanks
hi
I had a view in which I did something like this
isnull(fld,val) as 'alias'
when I assign a value to this in the client (vb 6.0) it works ok in sql2000 but fails in 2005.
When I change the query to fld as 'alias' then it works ok in sql 2005 .
why ?? I still have sql 2000 (8.0) compatability.
Also some queries which are pretty badly written run on sql 2000 but dont run at all in sql 2005 ???
any clues or answers ?? it is some configuration issue ?
Thanks in advance.
I am writing a pgm that attaches to a SQL Server database. I have an Add stored procedure and an Update stored procedure. The two are almost identical, except for a couple parameters. However, the Add function works and the Update does not. Can anyone see why? I can't seem to find what the problem is...
This was my test:
Dim cmd As New SqlCommand("pContact_Update", cn)
'Dim cmd As New SqlCommand("pContact_Add", cn)
Try
cmd.CommandType = CommandType.StoredProcedure
cmd.Parameters.Add("@UserId", SqlDbType.VarChar).Value = UserId
cmd.Parameters.Add("@FirstName", SqlDbType.VarChar).Value = TextBox1.Text
[...etc more parameters...]
cmd.Parameters.Add("@Id", SqlDbType.VarChar).Value = ContactId
cn.Open()
cmd.ExecuteNonQuery()
Label1.Text = "done"
cn.Close()
Catch ex As Exception
Label1.Text = ex.Message
End Try
When I use the Add procedure, a record is added correctly and I receive the "done" message. When I use the Update procedure, the record is not updated, but I still receive the "done" message.
I have looked at the stored procedures and the syntax is correct according to SQL Server.
Please I would appreciate any advice...
Hi all,
My SQL Server 7.0 is now running in a mixed mode authentication. I understand
that this method of authentication is not safe. So, Ive planned to change my
server's method of authentication from mixed to NT-only mode.
Kindly tell me what are the points I should consider for doing this, so that,
the existing data and the users are not affected.
Cheers and thanx in advance

We recently moved our SQL Server services to a dedicated machine, and things have gone relatively smoothly.
My boss's major concern is that now when he runs some scripts in another application that updates sales data with the newest info from the database, it pops up a login box with the correct information in it already, but they have to hit OK to finish running the script. This was not happening on the old server. I've double-checked the ODBC data sources are correct, and have compared the security for the 2 servers and they appear to be identical still. Has anyone seen this before or knows what I'm doing wrong?
Thanks in advance,

Hello !
I am having a problem with NT trusted connections. I am running a front-end from Access 97 with linked tables to an SQL Server. Whenever I open a form, I will be prompted for login. Since I am already on an NT domain, I make use of 'trusted connection'. However, whenever the form is refreshed or a requery is sent, I am always prompted for login again. Using an SQL user login does not give me the problem and it's a one time login.
Q : How do I configure SQL such that it doesn't prompt me for login everytime whenever I choose 'trusted connection' ?
Thanks.

I am reviewing the requirements for NT Authentication for SQL Server 7.0. I want to take advantage of window NT user security. I also want just a single security point.
My question is that I can make several NT groups for various users (DBA, development, accounting, finance, sales, etc.) but how are SQL Server roles, permissions, and passwords applied to these NT groups? There are no groups in 7.0, right?
We're having a small problem with our Authentication on SQL. We set SQL up to use NT Authentication only. We then created a group on the NT Server and gave it the necessary permissions to make changes to the MSSQL7DATA directory on the SQL Server. Next we created the NT Logins on SQL. We're using Access 97 & ODBC to connect to SQL. Problem is that the first time the users open an Access 97 table, they get a prompt asking for an SQL Username/Password, or a checkbox option to use NT Authentication. I've just been having them click the "Use Trusted Connection." Is there a way to force NT Authentication and avoid having that popup box show each time Access is opened? I'd like it so that the user does not see any boxes when they open the table. I have a feeling we've left something out on the SQL side. Thanks for any help you can provide.
