Service Account And CLR Security
Aug 6, 2007
By default does CLR code run under the SQL Service Server account or the SQL Agent Service Account? Does anybody have a link to BOL or MSDN???
My assumption is its under SQL Server Service Account.
I'm trying to satisfy the DBA's security concerns in regards to CLR Code. If the account it runs under (Agent or service) has zero privliges will a dba still be able to maintain the server? Wouldnt all their backups work under a privilaged account that isnt the SQL Server Service Account?
Double posted in security.

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.

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.
Thank you in advanced.

Hello! I have the following problem. I developed CLR Stored Procedure "StartNotification" and deploy it on db. This sp calls external web service. Furthermore, this sp is called according with SQL Server Agent Job's schedule. On my PC SQL Server works under Local System account and this web service is called correctly (Executed as user: NT AUTHORITYSYSTEM). But on ther other server the following exception is raised during job running:
Date 17.04.2007 16:42:10
Log Job History (FailureNotificationJob)
Step ID 1
Server MSK-CDBPO-01
Job Name FailureNotificationJob
Step Name MainStep
Duration 00:00:00
Sql Severity 16
Sql Message ID 6522
Operator Emailed
Operator Net sent
Operator Paged
Retries Attempted 0
Message
Executed as user: CORPmssqlserver.
A .NET Framework error occurred during execution
of user defined routine or aggregate 'StartNotification':
System.Security.SecurityException: Request for the permission of type
'System.Net.WebPermission, System, Version=2.0.0.0, Culture=neutral,
PublicKeyToken=b77a5c561934e089' failed. System.Security.SecurityException:
at System.Security.CodeAccessSecurityEngine.Check(Object demand,
StackCrawlMark& stackMark, Boolean isPermSet)
at System.Security.CodeAccessPermission.Demand()
at System.Net. The step failed.
What is the reason of this behaviour? Unfortunately I do not have direct access to this server.
I have the following guesses:
1) CORPmssqlserver may have not enough permissions to call web service
2) Something wrong with SQL Server account's permissions
2) Something wrong with SQL Server Agent account's permissions
I will take the will for the deed. Thanks.

Hi all,
I do understand that it is highly recomended to have aserprate user (perfered a domain user account) for each of the SQL Server service and SQL Agent service.
What is the reason behind that? (Someone told me to not run the service with an account that has a powerul privilegs! - I don't undrstanmd this point can you explain it please?)
What is the diffrent between: 1- Local System account 2 -Network Service account
Thanks in advanced!

Microsoft recommends that you do not use the Network Service account to run the SQL Server service (see http://msdn2.microsoft.com/en-us/library/ms143504.aspx).
Can anyone tell me what the drawbacks are of doing this?

Okay now this is weird, today the Reporting Services was not running and here are the entries in the event log:
Event Type: Error
Event Source: Service Control Manager
Event Category: None
Event ID: 7041
Date: 12/12/2007
Time: 9:47:22
User: N/A
Computer: TFS
Description:
The ReportServer service was unable to log on as DOMAINTFSREPORTS with the currently configured password due to the following error:
Logon failure: the user has not been granted the requested logon type at this computer.
Service: ReportServer
Domain and account: DOMAINTFSREPORTS
This service account does not have the necessary user right "Log on as a service."
User Action
Assign "Log on as a service" to the service account on this computer. You can use Local Security Settings (Secpol.msc) to do this. If this computer is a node in a cluster, check that this user right is assigned to the Cluster service account on all nodes in the cluster.
If you have already assigned this user right to the service account, and the user right appears to be removed, a Group Policy object associated with this node might be removing the right. Check with your domain administrator to find out if this is happening.
For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp
I am the administrator of the machines and I can assure you that no domain policy has changed for a couple of weeks. What should I look for?

I am currently hardening our SQL 2012 (with AlwaysOn Availability Groups) environment. Both the SQL service and agent account are using service accounts (only domain user). SQL browser service is disabled. Permissions to all roles are handled by using domain groups.
Currently a lot of (default) NT Service accounts are listed (some with sysadmin privileges). Are there accounts that can be removed?

Can you use a SQL service account (domain account) on two different SQL instances?
Can you set the SPN for both clusters instances with the same account?

Hi world,
I have a question, but first I need to give you some background:
My network works with Active Directory on Windows 2000, and I have web servers running on windows 2003 and SQL Servers 2000 running on Windows 2003.
I wanted to enable account delegation and I found a bunch of information.
Everything seemed "easy", but I tried to test it first on my test servers anyways and this is what happened:
We created the SPN for the SQL Server
Account is trusted for delegation check box was selected for the service account of SQL Server.
Account is sensitive and cannot be delegated check box was not selected for the user requesting delegation.
But when we checked the box Computer is trusted for delegation (and only this box !!) in the server running an instance of SQL Server 2000, the role of this server changed magically (just like this guys, it was magic) from "server" to "Domain Controller".
We were intrigued about this change, but we "trusted" the white paper that we had in front of us.
http://support.microsoft.com/kb/319723
After some hours, the production web servers (of the whole network) and many workstations stopped working:
The IIS on this web servers will show an empty list of websites
The network and dial-up connections were missing on the web servers and also on the workstations.
The web servers and the workstations affected were "isolated" from the network, the command ping was not finding any of this computers.
Anyway, it was a nightmare, it took a while to fix the mess, we reverted the changes in Active Directory, and this makes me thing that the magical "promotion" of the SQL server to Domain Controller had to do with all this.
the questions is:
Do you have an idea about what could have caused all this? I mean, I still need to enable this account delegation thing. But I would like to know first if someone has done it before in a similar environment or if someone has run into one of the problems described before.
Thanks world.

Hey Everyone,
I am testing restoring databases on another SQL 2005 server in out environment using HP data protector 5.5 and its great. However, I notice that the security login accounts do not get restored. If this is the case how do I go about getting accounts restored? Also, are there any other options?
Cheers,

I received the following when trying to deploy an 2005 analysis services package over an existing database:
The following system error occurred: No mapping between account names and security IDs was done.
We have redeployed this solution several times over the last week and have never encountered this error. The changes that we are deploying are related to partitioning of the measure group fact tables - and are not related to security in any way. Can someone assist?

Our system is MS SQL Server v7 and NT 4. We have a stored procedure that exec's xp_cmdshell to run an external program located on the server. When a user who has 'sa' rights runs this stored procedure it works fine. When a 'non-sa' user (via the "BuiltinUsers" NT account) runs it, xp_cmdshell produces the following error:
Msg 50001, Level 1, State 50001
xpsql.c: Error 1385 from LogonUser on line 476
Is there an NT security or SQL Server setting I've overlooked that can be changed to allow non-sa users to xp_cmdshell programs?
n.b. The BuiltinUsers account does already have execute permission on the xp_cmdshell procedure.

Hello all;
I am trying to form a replication system but at the very beginning i couldn't pass an obstacle.
While trying to create the Replication it says i have to change the user which starts the SQL Agent because the current starter user account is a system account and this will make the replication between servers fail.
"SQL Server Agent on OZN currently uses the system account, which causes the replication between the servers fail. In the following dialog box, specify another account for the service startup account."
I change it in the properties dialog box of the SQL Server Agent. The new account is the one I formed and granted accordingly. But it gives the following error when I try to apply the changes.
" Error 22042: xp_SetSQLSecurity() returned error -2147023564, 'No mapping between account names and security IDs was done' "
I tried many things, searched in the net, changed the owner of the database, applied new accounts, many grants, applied service pack 4, etc...
If anyone helps it will be very much appreciated. Thanks in advance...

Our software vendor rep is trying to upgrade MS SQL server 2008 SP4 to 2012 SP1. Get an error message: no mapping between account names and security ADs was done. He says that we get this error message because we have two domain controllers in our network, and one is running on the same windows server that run sql server. Out IT support disagrees to delete the second domain controller, saying it is recommended by Microsoft and he suggests that the problem is in Active directory.

Hi,
I am trying to set properties on a SQL Server7, but when I get to the tab for 'Startup Service account', it is greyed out. Also, the same for properties for SQL Server Agent.
Why can't I change it?
To schedule jobs, and have SQL mail, don't I need to set up a Startup Service Account?
Thanks for your help,

Has anyone ever converted from running SQL Server under the Local System account to running under a Domain User account?
I have often installed SQL using a Domain User account, but I am inheriting a couple of SQL Servers that were set up to run under Local System. I have never had to convert "on the fly" before.
If you have any input or insights, I would be grateful.

I just set up a SQL 2005 Server about a month ago that we will be moving all of our scattered DBs onto. I basically set it up with the default settings and didn't touch anything special, until I tried to install Microsoft System Center Essentials 2007 in our environment. I had problems getting it to use our SQL server, and a forum post told me to change all of the service accounts for SQL to use the LocalSystem login. So here are my service accounts:
SQL Server Integration Services
- NT AUTHORITYNetworkService
SQL Server FullText Search (MSSQLSERVER)
- LocalSystem
SQL Server (MSSQLSERVER)
- LocalSystem
SQL Server Analysis Services (MSSQLSERVER)
- LocalSystem
SQL Server Reporting Services (MSSQLSERVER)
- LocalSystem
SQL Server Browser
- LocalSystem
SQL Server Agent (MSSQLSERVER)
- LocalSystem
So Sandisk makes this software called CMC. It's for controlling their enterprise USB drives. And their software won't install. It errors out saying that it couldn't drop the database on our SQL server (but it doesn't exist). If I make an empty DB by the same name, it sees it, and then errors out anyway. I am using the SA login for testing (I was using a purposed SQL account before) so I don't think it's a rights issue. Sandisk says it should work, and they suggested I use SQL server express. But we run VMs, and running SQL server in another VM is going to use more of our memory pool. Plus we want centralized backups and all that.
Do my service account logins have anything to do with it? Can someone tell me what these should be set to by default so I can change them back?
Here's a trace I did when I tried to install the software:
-- network protocol: TCP/IP
set quoted_identifier on
set arithabort off
set numeric_roundabort off
set ansi_warnings on
set ansi_padding on
set ansi_nulls on
set concat_null_yields_null on
set cursor_close_on_commit off
set implicit_transactions off
set language us_english
set dateformat mdy
set datefirst 7
set transaction isolation level read committed
set implicit_transactions on
go
drop database [CruzerDb]
go
IF @@TRANCOUNT > 0 ROLLBACK TRAN
go
And here's more info if needed:
Product Version
- 9.00.3042.00
Edition
- Standard Edition
Server Collation
- SQL_Latin1_General_CP1_CI_AS
Is Clustered
- No
Is FullText Installed
- Yes
Is Integrated Security Only
- No
Is AWE Enabled
- No

Hi All,
I understand Sql Server Integration Services by default uses"NT AuthorityNetwork Service" account as service account. Is running SSIS using "NT AuthorityNetwork Service" account is good or should we create a domain account to run the SSIS service.

I am trying to install an SQL Express 2005 instance and have the built-in system account set to "Local system" because I was having some security issues while trying to attach a database. Is there a command line switch that will allow me to do this?
If there isn't then I will have to make sure the clients uncheck the "Hide advanced settings" checkbox and I would rather not have them do anything but hit the next button.

Thanks.
