What Persmissions To Give To The Application Account To The Certificate
Aug 14, 2006
Hey guys. I've an application which uses an account named Uaccount1. I've given it db_datareader and db_datawriter permissions to the tables. I've given it execute permissions to all sp's I've given it reference permissions to the symmetric key. And I gave it reference permissions on the certificate. At this point, it can't see the certificate. If I give control permission to the account for the certificate, it works perfect. Is it necessary to do that or am I missing something. Our security is based on symmetric key and certificates...
Hey guys. I'll have an active/active cluster and seperate accounts for SQL Services and Cluster service. The question is what rights should the cluster account have in SQL if I've removed the 'builtin admins' from SQL? Thank you
I'm creating one of my first asp.net pages, and it accesses an MS SQL database.It runs fine locally, but if you go to it remotely through a web browser, you get an exception saying that the database login failed for user ASPNET.My brother told me to do the following in SQL Server Managment studio. It seems I don't have that program installed, so I did it from the SQL command prompt.CREATE LOGIN [bigblueASPNET] FROM WINDOWSuse AdventureWorkscreate user [bigblueASPNET](Where "bigblue" is the computer name and "AdventureWorks" is the database my asp.net web page reads from).This only partially fixed the problem - now when you open the page remotely and try to access the DB I get an error message saying that permission to use the SELECT command is denied.I searched on these forums, and found this:http://forums.asp.net/69166/ShowPost.aspxFor future reference, let's call what my brother told me "Method 1" and what the previous poster did as "Method 2."I haven't tried method 2 because I don't know exactly what I am giving ASPNET permission to do. Does method 2 enable ASPNET to do anything to any database? It seems method 1 is more secure, as from the commands I could already tell it only has permission to access AdventureWorks.So, I'd prefer to use method 1. Can anyone tell me what further commands I can use to give ASPNET permission to do specific actions?If I can't figure out method 1 and have to do method 2, how can I undo what I did in method 1?Thanks!
hi all, i want to create a service broker application between two different instances. can i achieve the dialog security and transport security with out using certificate? like we can achieve the transport security using windows authentication (both the instances are in same domain). so how to achieve the dialog security with out using certificates.
I know it's bad to use the built-in SA account to access SQL Server from my ASP.NET application.
I did some reading but would like some suggestions as well. One article I read talked about Application roles in SQL Server. Is this the best way to handle SQL Server access for read/write/update/delete privileges from an ASP.NET application?
If this is the way to go, how do I set it up? Can anyone suggest a good web site to read up on this?
Hello I was hoping somebody out there could help me …..
We have a hard-coded application which uses the Sa account with no password. We want to add password to Sa – but when we do get users/DBAs calling us saying the application does not work.
How can we add password to Sa and get the application to work - unfortunately we do not have scripts for the application or know of the whereabouts of the developers.
Any suggestions/ideas – will be greatly appreciated
I am getting the error: Cannot open database "aspnetdb" requested by the login. The login failed. When I browse to my ASP.NET 3.5 LINQ web application on the IIS 6.0 server on Server 2003. I imagine this is because while I granted SQL Server 2005 login and permissions to my database that the application stores its data in, I did NOT grant any rights to the service account the IIS Application Pool uses for its identity to the aspnetdb database on SQL Server which is where all my roles information is stored at. My question is what are the MINIMUM permissions needed for this database so it can perform its roles related functions? I'm using Windows Authentications with the SQL Role provider for authorization.
Thank you.
EDIT: I think I only need to open the aspnetdb database and add my login to the aspnet_Roles_FullAccess role. Is that correct?
During install of SQL Server 2005, we can of course use a domain account or the built-in system account for running the services. I lean toward domain for obvious reaons but would like to know a +/- to each option and why I'd choose one over the other and what consequences or limitations one may encounter if I choose one over the other.
Hi, We are trying to implement Service Broker between SQL Server Express and SQL Server on the Same machine and we are having problems with certificates. We are creating a certificate on SQL Server, backing up the certificate on a file system and then loading certificate on the SQL Server Express from the file and we are keep getting the following error: Msg 15208, Level 16, State 1, Line 1 The certificate, asymmetric key, or private key file does not exist or has invalid format.
Following script runs fine on SQL Server.
Code Snippet
use master
Create Master Key Encryption BY Password = '45Gme*3^&fwu';
BACKUP MASTER KEY TO FILE = 'C:ServiceBrokerPrivateKeyMasterB.pvk'
ENCRYPTION BY PASSWORD = '45Gme*3^&fwu'
Create Certificate EndPointCertificateC
WITH Subject = 'C.Server.Local',
START_DATE = '06/01/2006',
EXPIRY_DATE = '01/01/2008'
ACTIVE FOR BEGIN_DIALOG = ON;
BACKUP CERTIFICATE EndPointCertificateC
TO FILE = 'C:ServiceBrokerEndPointCertificateC.cer'
Following script runs on SQL Server Express:
Code Snippet
Create Certificate EndPointCertificateC
From FILE = 'C:ServiceBrokerEndPointCertificateC.cer'
WITH PRIVATE KEY (
FILE = 'C:ServiceBrokerPrivateKeyMasterB.pvk',
DECRYPTION BY PASSWORD = '45Gme*3^&fwu'
);
If we run the script other way around, it works fine. If we use the SQL Server on some other machine, the script works fine. But only on the same machine, it throws this error. We made sure the permissions and everything. Let us know if there is any work around or what are we doing wrong.
I have been running a script in SQL Server 2000 as sa also as a Active Directory user who has administrator rights (I tested both approaches SQL Server then Windows Authentication) in Query Analyser which grants execute rights to the stored procedures within the database instance and Query Analyser does not give any errors when I run the script. I have made sure that each transaction has a go after it. I then return to Enterprise Manager, check the rights (I apply them to roles so that when we create another SQL Server user we just grant him/her rights to the role) and discover that the role has not been granted the rights. I seems to be occurring only with 2 of the procedures. Is there a known bug that might be causing this?
I have several DTS jobs that runs well as a job with my nt login account for the SQL agent service startup account, but if I use the System account they fail with this error. " Error opening datafile: Access is denied. Error source: Microsoft Data Transformation Services Flat File Rowset Provider"
The data has change access to the System account under the NT security.
Basically a dts package has been setup that pulls in data from another companies server, this data requires to be on-demand i.e individual users can pull in updates of the data when they require it.
I am using xp_cmdshell and dtsrun to pull in the data. This obviouly works fine for me as i am a member of sysadmin.
Books online quotes " SQL Server Agent proxy accounts allow SQL Server users who do not belong to the sysadmin fixed server role to execute xp_cmdshell"
So i went to the SQL Server Agent Properties 'Job System' tab and unchecked 'Non-sysadmin job step proxy account' and entered a proxy account.
The proxy account has been setup as a Windows user with local administrator privilages and even a member of the sysadmin server role - just in case.
Now when i log onto the db with my test account - a non-sysadmin - and attempt to run the stored proc to import the data i recieved the message 'EXECUTE permission denied on object 'xp_cmdshell', database 'master', owner 'dbo' '
hmm... so basically i have either misunderstood BoL or there is something not quite right in my setup.
I have search the net for a few days now and yet i can find no solution.
Hi there,BOL notes that in order for replication agents to run properly, theSQLServerAgent must run as a domain account which has privledges to loginto the other machines involved in replication (under "SecurityConsiderations" and elsewhere). This makes sense; however, I waswondering if there were any repercussions to using duplicate localaccounts to establish replication where a domain was not available.Anotherwords, create a local windows account "johndoe" on both machines(with the same password), grant that account access to SQL Server onboth machines, and then have SQL Server Agent run as "johndoe" on bothmachines. I do not feel this is an ideal solution but I havecircumstances under which I may not have a domain available; mypreliminary tests seem to work.Also, are there any similar considerations regarding the MSSQLSERVERservice, or can I always leave that as local system?Dave
I have a situation that I have discovered in our QA database that I need to resolve. When I looked at the Activity Monitor for our server, I discovered that a process is running under a domain user account for one of our .Net applications. The problem is that that domain user account has not been created as a SQL login account on the server. I am trying to figure out how someone can log in to the database server with a domain user account that has not been added to SQL Server as a login account.
Does anyone have any insight on this? I don't like the idea of someone being able to create domain account that can access the database without me granting them specific access.
have SQL Server 2005 std edition SP1 installed on Windows 2003 Std edition .Configured Transactional (single Publisher and no clustered environment.) Replication past two months working fine, Now 1.Distrib.exe application err is coming.
Due to which my job is failing (Distributor to Subscriber). Iam attaching thw file. Thanks Sandeep
I am trying to create a encrypted row in my database Everything here worked except that when i run the final query to decrypt the data It just comes up with null for each row. Even if i do a query to show me the rows that are not null It's like it is saying yeah there is data here but I am only going to show you null instead of what I am supposed to decrypt.Here is what I tried from start to finish Create Certificate TestCert Encryption By Password = 'Password' With Subject = 'SQLCert', Expiry_Date = '12/01/2050';
declare @Test nvarchar(50) set @Test='123456789'
insert into testenc (testencry) Values (encryptbyCert(Cert_ID('TestCert'),@Test ))
select convert (Nvarchar(50), DecryptByCert(Cert_ID('TestCert'), testencry,N'Password')) As Test from testenc
im trying to drop all certificates on my database, and then the master key, but cannot do this as there are objects encrypted by one particular cert that i called fcert. I done this ages ago and cannot remember what i encrypted with this cert. to drop the master key i have to drop the cert and to drop the cert i have to make sure no objects are encrypted by it. how is this achieved?
I can use "CREATE CERTIFICATE" to add a CER certificate into a SQL database. How can I do so with a PFX certificate? From the document, it can be done so with a CER file and a PVK file, but only a PFX file.
hey, I am having a weired issue(donno whether its weired or not.). I have a user who has db_owner rights on a database. But when he is trying to create a certificate he is getting error. "Msg 15247, Level 16, State 1, Line 1 User does not have permission to perform this action." Remember he is having db_owner rights on that particular database. is there any other permission that i have to give him.
I'm having this really strange issue with mirroring.
I've followed the instructions on http://msdn2.microsoft.com/en-us/library/ms191140.aspx to the letter, leaving out the witness server part, as I don't have one.
All works OK, but when activating the mirroring on the principal server I get the usual error 1418 error. I fired up SQL Server Profiler to see what was happening, and the following error emerged.
Connection handshake failed. The certificate used by the peer is invalid due to the following reason: Certificate not yet valid. State 104.
I am trying to get SQL Express to use a certificate for SSL encryption between the server and client. Our company has a certificate server and I already did generate a server certificate from it. I installed the certificate in the "local machine" store and I also have the CA certificate in the trusted root on the server machine. (XP PRO)
When I use the configuration tool, I get to the "protocols for SQLEXPRESS" area, I click properties, I select the certificate tab, but there are no certificates available from which to choose.
Can someone shed some light on where I might go from here?
As we know ,certificate is a digitallly-signed security object that bind the public key to the principal who holds the private key.
Say i create a certificate by using create certificate DDL, then use it to encrypt data and decrypt data as follows:
Code Block create certificate cert1 encryption by password='p@ssw0rd1' with subject='certificate test' go declare @plaintext varchar(100) set @plaintext='abcd' declare @cipher varbinary(8000) set @cipher=encryptbycert(cert_id('cert1'),@plaintext) select convert(varchar,decryptbycert(cert_id('cert1'),@cipher,N'p@ssw0rd1'))
Is that mean i create public key implicitly when i run "create certificate cert1 encryption by password='p@ssw0rd1' with subject='certificate test'"?
What cryptography algorithm would be use when i use the certificate to encrypt data ? Where is private key? I ensure I use the public key which generated from "create certificate " DDL to encrypt data .I want to know which private key i used when i execute decryptbycert to decrypt.
What I wont is to be abele to do is to send a message from €śSender€? to €śReceiver 1€? or €śRecevier 2€?.
I am abele to send a message from €śSender€? to €śReceiver 1€? but if I send a message to €śReceiver 2€? I get a dialog security problem I think. If I use profiler I can se in €śReceiver 2€? the events:
Broker:Connection Audit Broker Login Broker:Message Classify Audit Broker Conversation = Certificate not found Broker:Message Undeliverable
And I cant find what´s wrong, this Is my scripts for etch instance.

I have been trying to create a certificate for use with SQL2005. I found openSSL to create a cert but I am not sure how to use it.
When I go into SQL Config Manager / Protocol Properties / Certificate Tab... I do not see any certificates. The list is empty. Where are these certs pulled from and how can I create one on my own?
Here are the Reqs:
Certificate Requirements
For SQL Server 2005 to load a SSL certificate, the certificate must meet the following conditions:
The certificate must be in either the local computer certificate store or the current user certificate store.
The current system time must be after the Valid from property of the certificate and before the Valid to property of the certificate.
The certificate must be meant for server authentication. This requires the Enhanced Key Usage property of the certificate to specify Server Authentication (1.3.6.1.5.5.7.3.1).
The certificate must be created by using the KeySpec option of AT_KEYEXCHANGE. Usually, the certificate's key usage property (KEY_USAGE) will also include key encipherment (CERT_KEY_ENCIPHERMENT_KEY_USAGE).
The Subject property of the certificate must indicate that the common name (CN) is the same as the host name or fully qualified domain name (FQDN) of the server computer. If SQL Server is running on a failover cluster, the common name must match the host name or FQDN of the virtual server and the certificates must be provisioned on all nodes in the failover cluster.
I have SQL Server 2012 and want to encrypt my connections by using a wildcard [URL] ssl certificate from a trusted party. After installing my certificate i want to selecti in in de SQL Server Configuration Manager but the certificate does not appear in the properties of protocols.
In older versions it was possible to add the thumprint of my certificate to the registry, but in this version that result into a sql server that cannot be started anymore.
