How To Check/verify SQL Login Credential
Nov 15, 2007
Hi,
I am making a module to backup SQL Db from webpage. I impersonate asp.net user to a given Windows Account and need to verify that account has required permission in SQL Server.
I don't know how to verify the windows account credential for SQL Server login.
Now what I am doing is to run SQL query against database to select row from some table, if it is successful, the user is valid SQL login. But I know it's not the way.
Any idea?
Thanks,

is any way to select SQL logins that are Mapped To Credentials as using this query I get only NULL:
SELECT credential_id FROM sys.server_principals WHERE name = 'test_login'
I see the list of Mapped Credentials in SQL login properties with GUI, but can not select this option.Â

In SQL Studio, I can go to the restore window and the click "verify backup media". This would check the restore plan listed in this window and check if some of the file are missed.Is there any way to reach this with TQSL? I know there is a "restore verify" command, but this will only verify one backup/file and not the complete restore path. I'm looking for a TSQL solution which is able to control that all necessary backup files are still present on the file System and not moved or deleted (e.g through cleanup task).

I am trying to learn how to store a web form password and than check it when the user log in. So far none of the code I can find works.
Why the following test does not work and what the correct code should be?
Insert Into [user]
values ('name', 'email', HashBytes('SHA1', 'bob'))
GO
Why does the following produce no rows?
SELECT *
From [user]
Where HashBytes('SHA1', password) = HashBytes('SHA1', 'bob')

I have a sqlserve, which service account is 'local system', running in machine A.
A credential ,which associated a windows user U1 in machine A, mapped to a sqlserver login Login1.
A file named 1.txt that only can be accessed by U1 in machine A.
A CLR procedure P1 that would read the 1.txt file.
I encounter a error when i access the 1.txt file through P1 as Login1:
A .NET Framework error occurred during execution of user-defined routine or aggregate "HelloWorld":
System.UnauthorizedAccessException: Access to the path 'E:1.txt' is denied.
System.UnauthorizedAccessException:
at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
at System.IO.FileStream.Init(String path, FileMode mode, FileAccess access, Int32 rights, Boolean useRights, FileShare share, Int32 bufferSize, FileOptions options, SECURITY_ATTRIBUTES secAttrs, String msgPath, Boolean bFromProxy)
at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access, FileShare share, Int32 bufferSize, FileOptions options)
at System.IO.StreamReader..ctor(String path, Encoding encoding, Boolean detectEncodingFromByteOrderMarks, Int32 bufferSize)
at System.IO.StreamReader..ctor(String path)
at StoredProcedures.StoredProcedure1(SqlString fileName)
.
I think it need a credential when a sqlserver login access some resource outside the sqlserver, so i add a credential and mapped to the login
any suggestions would be appreciated.
And please correct me if i have any inaccurate concept.

There is one thing that€™s confusing me in creating a proxy account.
I am trying to get an SSIS package configured as a SQL Server job and execute it from a non-sysadmin login. But when I execute it gives the error message:
Non-SysAdmins have been denied permission to run DTS Execution job steps without a proxy account. The step failed.
I know that we have to create a proxy account for this to happen and creating of proxy account prompts me to choose a credential, and that is where I do not understand the logic. From MS website I can find the following, but it is confusing to me
This proxy account must use a credential that lets SQL Server Agent run the job as the account that created the package or as an account that has the required permissions.
ref: http://support.microsoft.com/default.aspx?scid=kb;EN-US;918760
I tried reading all the related articles, but still the process of creating the credential is confusing to me, can someone throw some light on the logic of proxy/credential here?
Thanks

I have a report using an XML data source. The data source is calling a web service method which returns the XML file. The security setting is "Use Windows Authentication (Integrated Security)" in the report. The web service and report are both deployed to ServerA.
The web service is pulling data from a file share. Only certain users have access to this share and they are identified in the <authorization> element of the web.config file in the web service.
If I open Internet Explorer on ServerA and go to //localhost/Reports, I can navigate to the report, run the report and everything works fine.
If I open Internet Explorer on ClientZ and go to //ServerA/Reports, I can navigate to the report. However, when I run the report I get a "Failed to execute web request for the specified URL". I do not believe my Windows Credentials are getting passed to ServerA from ClientZ.
Is this a known bug or am I doing something wrong in my set-up?
Thanks,
bbossi

Due to a previous (mis)configuration, i need to grant readwrite permission on a share from a MSSQL DB User.The SQL user will launch t-sql queries on demand and they cannot be scheduled.
I've created a credential object in SSMS, configured it with the correct AD user and mapped it to the MSSQL DB user.Now, if i execute a simple t-sql backup:
BACKUP DATABASE [DB] TO DISK = N'IP.ADD.RE.SSshareDB.bak' WITH NOFORMAT, NOINIT, NAME = N'DB-Full Database Backup', SKIP, NOREWIND, NOUNLOAD, STATS = 10
GO
I get an access denied error, monitoring the sqlserv.exe process via procmon, i see that the Sql Server process is not impersonating the AD user configured in the credential, it still try to access using the local machine account .

Hello,
Our department will create several SSIS packages that will contain connection managers that use the IBM or Microsoft OLE DB provider for DB2. In every case, we will have to use a specific user name and password.
We need one point of reference for the password for the multitude of packages in case the password changes. I'm guessing that we would do this with a single XML package configuration that each of these packages could use. If this is the case, how can it be done securely?
Are there other ideas that I should consider?
Thanks!

Looking for opinions here on what is the best way to programmatically test that a password change to a credential has occurred successfully.
The password change was made using Alter Credential, and I can see in sys.credentials that the credential was updated by the tool that handles these updates. I would just like to be able to confirm that all of the credential updates were successful (in other words, they authenticate correctly) before anything starts to fail.
Assume that the number of SQL Servers is too great to manually check them even if the whole team worked on it together.
Thanks in advance!!

I need to give the below script which contains CREATE CREDENTIAL query to an app team.
CREATE CREDENTIAL crdntl WITH IDENTITY = '<service_acct>',
SECRET = '<pwd>'
GO
My concern is i don't want the password to be visible. Basically i want to use this credential to create a proxy which is then used to run SQL Agent backupjob on number of SQL servers. Also, i cannot leave the SECRET value as blank (as the MSDN suggests.)
Is there any way to mask the password OR any other alternative solution.

We are running SQL Server 2012 on Windows 2008 Server. I created a credential with a proxy account. In creating the credential, it asked for an Indentity and Secret. I used my windows login and password. Now, I have tested the credential and proxy account by executing a Job which calls a SSIS Package. What is the 'best practice' to use when creating a credential? Should the credential be created with another windows login, created with the same abilities as my windows login, with a non-expiring password? Should that new windows login be used as the owner of my job with the Agent?

I have a scenario where I want to make a linked server query and report using windows service account credential. I can able to do link query if I RDP into the Server where linked server established using the service account and run query successfully  but local client SSMS with my credential fails connecting linked server or querying. Looks to be a sql double hoping problem if so configuration each client domain account to enable delegation will be challenging as mentioned in the following articles instead service account only might work if possible.

I haven't written any .net database updates before. I wrote the following code for a visual web developer application and it appears to work. There is no close function or anything. Will the adapter, builder, dataset, and row objects be cleaned up and disposed of properly? Please tell me if I need to include anything else. The connection object is made elsewhere. ThanksDim adapter As New Data.SqlClient.SqlDataAdapter("SELECT * FROM Inventory WHERE InUnique=" & ListValue.Value, connect)

Hi, all!
I'm really confused about how to run a query on the database to check to see the CustomerID filed value already exists in the database.
If it’s true, I want to display a message: “Valid� the user to proceed with the next steps
Else
Display the customer number doesn’t exist in the database, and cancel.
I tried all sorts of things and I just can't get it to do it. Hopefully you can help. Thank you

I want to ensure that it produces the same results as the 'Group By' clause of the MS Access fragment below.

Dear SQL,
I need to SELECT something from a database that has a UNIQUEIDENTIFIER (GUID) field,
If the number is wrong (has some other than A-Z 0-9) than the ASP page just freaks out and gets "error converting from a character string to uniqueidentifier"
How can I check that the GUID is OK before I SELECT ?
this is the number format:
{7A9B5F81-4936-4A31-B4E2-9168AAB75A0}
I tried to cast this "error" number with no successs:
"WHERE Deceased_ID = cast('"& "---------4936-4A31-B4E2-9168AAB75A0" &"' as uniqueidentifier)"
Thanks in advance, Yovav.

I am working on sql integrating with Hybris. Most of you are not aware of hybris as it was a new technology.
In hybris we will create some classes and in those classes we will insert some tables. These tables will be automatically inserted into the sql server. No need to manually insert them the hybris structure will insert it. So my doubt is, how can we find out whether all the records have been inserted into sql database or not how we can check that.
Is there any way?? We have those classes in wich we can see which tables are there. Or else from the data model itself we can see what are the tables avilable or shud be inserted into sql thru hybris.
Can we check by giving all the table names in a single query?? or is there any other way to find out. If we can check by giving all the table names in single query how we need to give it.
