How To Authenticate Users Using User Login And Password Stored In SQL Database?
Feb 2, 2007
Hi. I have a DetailsView with Bound Fields "Login" and "Password". This informations are stored in SQL database. How to solve such authorization? How to compare password stored in database against passowrd typed by user? Is this a good idea to use CustomValidator control to write some checking procedure?. Regards. Pawel.
Ideally, I'd like to have the reports use windows authentication, ie grab current user/password so long as user does not have to enter it manually. If that is not possible, then how do I make it so user does not have to enter this info manually? My theory is that I have IIS set up incorrectly for doing this, but I'm not familiar enough with either reporting services or IIS to find out.
I have a NT Group of users that need to connect to MSSQL db using integrated auth and run a stored proc. I have got this concept to work for individual windows users but not a group.
Does anyone have any ideas?
(Win XP, MSSQL 2000 SP3, Windows Group = "SQLUsers", member is "User2")
--- TSQL ---
USE master GO sp_grantlogin 'pcSQLUsers' GO sp_defaultdb 'pcSQLUsers', 'theDB' GO USE theDB GO sp_grantdbaccess 'pcSQLUsers', 'SQLUsers' GO GRANT EXECUTE ON [dbo].[uspThing] TO SQLUsers GO
-- Trying to connect with OSQL.EXE:
> osql -d theDB -E Login failed for user 'pcUser2'.
BUT.....
runing it for the individual user:
---TSQL
USE master GO sp_grantlogin 'pcUser2' GO sp_defaultdb 'pcUser2', 'theDB' GO USE theDB GO sp_grantdbaccess 'pcUser2', 'SQLUsers' GO GRANT EXECUTE ON [dbo].[uspThing] TO SQLUsers GO
---- now trying to connect with OSQL.EXE as User2:
SQL Server 2005 Express will not allow me to change the password for my login user. I tried deleting the user and re-creating the user. Another password is being put in although the password I put in was accepted. I even test to see what would happen if I left the password blank. It got accepted. But when I look at the password for my login user again, a different and much longer password was put in. I even tried this T-SQL statement:
CREATE LOGIN <loginname> WITH PASSWORD='<passwordname>', CHECK_EXPIRATION = OFF, CHECK_POLICY = OFF
Earlier one of my team member has created a user login and password but forgot the password after few days and now we need to know the password of that login. Some of the application are using this login so we can delete and create a new login with the same name hence is there any possibility or script to find out the password of the existing login.
i'm using the Enterpirse library logger to write logs into a database. When choosing connection string i choose the database i want in the "connection properties" dialog box and push 'Test connection' button. everything goes well.
then i open the SQL Server Management studio express and connect to the databse to check some things, from that point on , when i push the 'Test Connection' button in the Enterprise library i get the error:
"cannot open user default database. Login failed. login failed for user My'server/MyuserName'"
even when i close the sql server manager , it is still stuck - the connection test doesn't work anymore.... it only work when i restart the computer.

Been looking through the forums for a solution to this problem.I already tried granting access through statements such as:exec sp_grantloginaccess N1'machineNameASPNET'But they don't seem to work.. i vaguely remember seeing somewhere a DOS command line statement that grants access to the ASPNET_WP and that fixed my problem before on another computer.. but this is a new computer and i forgot to write down the command.Can anyone help explain and propose a solution to my problem. Many thanxs.
I am using the MSDE to connect to my ASP.NET application. I get this error after clicking the login button of my login page. Anyone know why this would happen?
Thanks for any help,
Cannot open database requested in login 'DataSQL'. Login fails. Login failed for user 'serverASPNET'.
I have an application which uses a login with an encrypted password. Everything works well, no errors in the application. My SQL Server errorlogs keeps recording:
Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.
I know this message is related to the login with the encrypted password (tracked it with Profiler) My question: Is it normal that the error log tracks this message because the password is encrypted?
SQL Server 2005 Express keeps putting in a different password than the one I chose. I would check the properties on the login I want to change. Then I change the password and it gets accepted. When I try my web application, I get the dreaded "login failed for <loginname>". I look at the properties again and see my password never change. Is this a bug? I ever tried this syntax to no avail:
CREATE LOGIN <loginname> WITH PASSWORD='<mypassword>' CHECK_EXPIRATION = OFF, CHECK_POLICY = OFF
M trying to create a logon form I had something in mind but i can work it out yet
When the user wants to login into the application the value of textbox must be compared with the datafield in the sql server. And then i want a messagebox to show up.
I created a table in sql server with 2 fields in it , User and Password.
I��m working on an application that needs to support multiple users without log in and out of Windows. I would like to use trusted/integrated security (domainusername) so I.T. does not have to manage two accounts per operator. Is it possible to use trusted accounts (domainusername) in the SQLClient.Connection object?
Hi when i try and open a database in sql server management studio i get the error "Cannot open user default database. Login failed. Login failed for user 'DOMAINUser'. (.Net SqlClient Data Provider)", what can i do to rectify this, i have googled around and still havent found no answers.
Hey Microsoft: this affects development that will eventually sell a lot of seats on SharePoint Server 2007. If you guys and gals can't straighten out this mess, you can't expect custom solutions with custom web parts. So pay attention for your own good. Yes, SPS 2007 is what this is all about. I've created simpe web parts and deployed them, same VS 2005, but I need local development and debugging for more complex stuff. I'm really disappointed that you have no solution for this problem.
I've seen other posts on this, but the result seems to be the same: if you fix it, it's by accident, not by design.
1. I created a blank ASP.NET web site
2. I added a web part manager
3. I added a web part zone
I get the error described above. I have no idea why SQL Server settings are so screwed up.
I've tried all the stuff in the other posts - security settings, command line installation, etc. None of those worked.
The default template(s) don't copy anything into App_Data, nor create an empty folder. I don't know why that is. I have other web sites working just fine, but they use remote SQL databases, or local ones I created, and didn't need profile management (no forms authentication, no web parts, no web zones).
I've also started out with a local database, using SQL Authentication, later moving it to a remote server, and never had any problems. The SQL Server developer edition and Express seem to work just fine. I can also debug stored procs when the .mdf is in App_Data. So the problem isn't one of connectivity.
What would cause the default screw-up? This would seem to point from all directions to a problem with Visual Studio (2005)? The installation is defalt - perhaps some extras included (copy local), but nothing unusual. AJAX for ASP.net is installed, but not used in the above "default web site" trial. Likewise Syncfusion's tools, which work fine on other developer workstations at this same location, all of which are from the same image (purchased at the same time & imaged). That web parts work on other boxes, running all the same management tools (anti-virus, remote sys admin/sms etc.) makes none of those suspect.
I think Microsoft needs to have a clean problem solution and publish it. SP1 certainly doesn't fix it. What's worse is the stupid, lame error message. "I can't open the default database". Well, what did you try? What do you think the default is? What settings are you using? Why is there no debugging information other than the usual worthless trace information showing it's all deep within the ProviderBase and SqlClient namespace code? How is that supposed to be helpful?
If anyone has anything solid, not guesses, I'd like to know.
Where is located the hash password for the contained database users?I have a script that prints all creating statement so that a Dev environment security can be reapply after a prod data refresh but I can't find the table containing the hash password when the user is "with login" for contained database.
I have a stored procedure that validates a user login against a username and password field. How can I ensure case sensitivity in the stored procedure for the password field?
Hi I have asp.net2 app using SQLExpress which works fine in VS2005.

I tried using Query Notification on my computer at home: * Win XP Pro with all the SPs and hotfixes * SQL 2005 with SP1 qand hotfix
Query Notification worked fine.
Then I tried using it at work:
* Win XP Pro with all the SPs and hotfixes
* SQL 2005 with SP1 qand hotfix
and I see the following error in the SQL server log file and notification does not get to the client app:
---------------------------------------------------------- Date 9/1/2006 10:18:30 AM Log SQL Server (Current - 9/1/2006 10:18:00 AM)
Source spid17s
Message An exception occurred while enqueueing a message in the target queue. Error: 15404, State: 19. Could not obtain information about Windows NT group/user 'domainmyuser', error code 0x6e. ----------------------------------------------------------
A similar error shows up in the machine's Event Log.
I am sysadmin and full OS admin on both boxes. The difference is that the computer at home is standalone while the one at work is part of a domain.
I am in a situation where I would like to use a SQL login instead of adding individuals windows login to the server. Is there a way to force a login instead of having the report server not give rights at all??
hi, so i have a new box and I'm trying to get my websites and SQL Server 2005 Standard Edition working on it, but the pages give me the following error when I try to load them: "Cannot Open Database "XXXX" requested by login. The login failed. Login failed for user 'xxx'" Everything seems exactly the same settings and user-wise from my old box to my new one, but nevertheless everything I've tried gives me the same error. I've tried creating new users in SQL Server and giving them appropriate permissions to my database. I've even tried just using the built in 'sa' account. Nothing seems to change the error, except when I give it the incorrect password then it just says 'login failed' This leads me to believe that i'm successfully logging into the SQL Server, but it doesn't want to give me access to the database I'm requesting access too. But "apparently" the account i'm using should have access to the database. If nothing else the 'sa' account should, but that didn't work either. I'm stumped. Any ideas?
I Guys I am trying to create an application that writes data to a SQL database (studio express). The application works fine but as soon as I open the table with the SQL server management studio express the application does not work any more displaying the following message:
��Cannot open user default database. Login failed. Login failed for user���?
If I siwtch off and on the computer the problem disappear till the table will be open with the database management studio express!!!!!
We build up a new website in .net mvc 4.0 on a w2012 server with MSSQL 2012 database.We use windows autentification and normal anonymous access through NT AUTHORITYIUSR who is also a login in the database.But we make extra login possibility for users who are registered and they can insert and modify data in some tables in the database. And I'am afraid of giving NT AUTHORITYIUSR insert and update for some column in tables.I think of set up a new login for the database. Run a new connection string on login and set up special permission for that extra user on the database, and let the user become a member of the ordinary user on the database.

Hi, I'm new to SQL Express 2005. I found information regarding : "Cannot open user default database. Login failed."on this forum but I think that in my case it's a bit different issue. I have a website (ASP.NET 2.0) accessing DB, in the mean time Windows Service tries to update some data in the same DB (Service runs as NT AUTHORITYLOCAL SYSTEM). The second connection is rejected: "Cannot open user default database. Login failed.Login failed for user ....". Problem occurs only when both: service and website are running at the same time. So service and website are running without problems when they are connecting DB exclusively. My connection string is: "Data Source=.SQLEXPRESS;AttachDbFilename="|DataDirectory|spider-lab.mdf";Integrated Security=True;User Instance=True"
I am migrating a database TESTDB from SQL 2008R2 to a new server running SQL Server 2012.
Management has decided the current sql users should have "better" user names. So the login and username "BadUsername" on the old server should be called "GoodUserName". Goodusername should have the same permissions as Badusername.
I have now restored a backup from the old server to the new server.
I used the following script for creating the login:
CREATE LOGIN [GoodUserName] WITH PASSWORD=N'difficultpassword', DEFAULT_DATABASE=[master], DEFAULT_LANGUAGE=[us_english], CHECK_EXPIRATION=OFF, CHECK_POLICY=OFF GO
Then I run the following script:
ALTER USER Badusername WITH LOGIN = GoodUserName, NAME = GoodUserName
But the results are not what I wanted. I now have two database users: Badusername and GoodUserName. I would have preferred if BadUserName was "replaced" by GoodUserName, but it won't be a problem if I have to delete badusername manually. Worser is that GoodUserName have NOT "inherited" any permissions from Badusername.
Is there an easy way to transfer permissions or do I need to loop through the permissions of badusername and apply those to badusername?
we have an application which lets users connect to production database with windows credentials, They are able access the sql tables too with windows login. I want to restrict them from accessing the sql tables. How do I do that.?I tried a db_deny but that prevented them from accessing the application too.
I'm sorry if this is simple, I'm no DBA but have been tasked with solving this problem...
We have a website that connects via ODBC to SQL Server (2k sp1) and at the moment I am getting back about every other time:
Microsoft OLE DB Provider for ODBC Drivers error '80004005'
[Microsoft][ODBC SQL Server Driver][SQL Server]Cannot open user default database. Login failed.
So this is NOT happening every single time. Now I have seen Microsoft KB - 307864 and I can see that none of the databases are marked as suspect, the database I am trying to connect to does exist and is attached and, I have run the command to switch the database to multi-user mode.
The probable cause of this problem is that a while ago we had a hard-drive failure and I was forced to reattach some old datafiles (mdf,ldf) as the database. This seemed ok and I can view data etc in enterprise manager no problem.
I have checked for orphaned users and the user I am logging in with from the webpage is not listed.
So does anyone have a clue as to why this is happening, and more frustratingly for me, why is it only happening some of the time.
