Row-level Security: Permissions Required On Base Table?
Jun 2, 2007
I'm implementing row-level security in a SQL Server database that uses Microsoft Access for the front end. I'm using a UDF (a view behaves the same way) to restrict access to specific rows of a base table based on membership in a role. According to the reading I've done, if the base table has DENY ALL permissions for the role, and the UDF has GRANT ALL, members of the role should be able to update records in the base table via the UDF, without having direct access to the base table. However, I find that unless I grant appropriate permissions on the base table, the user is unable to update the table via the UDF.
Is this expected behavior? Nothing I've read suggests I should have to grant permissions on the columns of the base table.

I have prepared several DTS packages which must be launched by a custom external application. What is the best way to provide access to this application? What are the minimum security requirements? Currently, they are local packages; I understand that some utility is offered by saving them as .DTS files, but I don't know the pros & cons. Are there advantages to using the Repository? The app should be able to do its work from a different box on the same network as the server. (Ultra-super-secret security isn't an issue, but I don't want to have give our developers sa-level access unless necessary.)

I have a situation where I have Table A, Table B.
View C is created by joining table A and table B.
I have written a instead of trigger D on view C.
I do not insert/update/delete on the view directly.
For every insert/update in table A /B the values should get insert/update in the view respectively. This insert/update on view should invoke the trigger.
And I am unable to see this trigger work on the view if any insert/update occurs on base table level.
Trigger is working only if any operation is done directly on the view.

I am writing a SQL 2000 stored procedure which uses an €˜EXEC @sqlString€™ statement. The @sqlString is generated at runtime. I want to give as few permissions as possible and currently allow users to access the database tables using only the stored procedures provided. However, with €˜Exec€™ I discover that I need to grant permissions on the actual tables to the users or groups. I would like to avoid this. I would also prefer not having to maintain a separate user with table level permissions and hardcoding the stored procedure with these details.
Is there anyway for me to dynamically generate the required SQL statement within my stored procedure and let SQL know that this stored procedure is allowed to select whatever tables it wants to without having to define permissions on the tables?

Hi everybody:
We have recently migrated our DDBB from SQL 2000 to SQL 2005 in several Servers. We have 2 DDBB per Server and the size of mdf files are between 10 and 40 GB.
We put Compatibility Level in 90 in SQL 2005 but when we arrive at work we see that our Maintenace Plans failed because the Compatibility Level of one of Data Bases changed to 70.
We have a Trace executing the whole day registrying the execution of stored procedure 'sp_dbcmptlevel' but in despite of Compatibility Level changes, the Trace does not registry anything.
Has anyone passed before me for this situation? Thank you in advance and greetings,
Nuria

This may be the wrong forum for this - if so, please direct me to the appropriate forum.
I've
recently upgraded to MSSQL 2005 and I'm trying to execute the
sp_databases stored procedure, but I'm having what looks like
permissions problems. I can execute the stored procedure, but it
doesn't return any results. As far as I can tell, the problem is that
my userid can't see any rows in sys.master_files (I can select from the view, it just doesn't return any rows).
I've tried any
number of things to get this to work, but the only thing that's been
successful is to change my userid's database role membership to
db_owner. In the long run, this isn't really a viable solution for me,
since my userid should only really have read(select) access to the
database in question.
I'd appreciate any pointers that you can
give me - I figure I'm doing something stupid, but haven't been able to
figure out what, yet.
Thanks,
Jeff

Good Afternoon All:
We have a SQL2K5 SP2 (x64) in active/passive cluster running an ERP application database.
I have users in remote office who are requesting the ability to run the "standard reports" from SSMS such as Disk Usage, Disk Usage by Table and so on. The user in question has AD account within the instance with db_datareader role.
What other database or server defined role is required to allow this user to launch and view the standard reports from SSMS?
Thanks!

I've got a Server setup at work on our RD domain
It's Windows 2012, running SQL Server 2012 with reporting Services
I've installed our application and reports to this server.
If I'm on my CORP domain on my development laptop I can enter the following into IE [URL] ...... and the SSRS reports page opens up fine
I then RDP into this server using my same CORP credentials Open IE on this server and enter the same URL within IE and get User 'CORPORATEjoep' does not have required permissions. Verify that sufficient permissions have been granted and Windows User Account Control (UAC) restrictions have been addressed.
I'm on the Server itself. Why does my account not work there, but when I access SSRS from outside this SERVER with same login, it works

I'd like to cancel my long running Reports via ReportingService2005.CancelJob(). It seems, while I'm able to start a job I don't have the permission to cancel it. I always get the error message:
The permissions granted to user '<my-account>' are insufficient for performing this operation.
Do I have the be a member of a special group on the server running the Reporting Services?

Hi all,
what are the minimum required permissions for being allowed to deploy a report? When I try to deploy a report in BIDS I get the error message that my user has not sufficient rights for doing so.
Some key data for my configuration:
Windows Server 2003 Standard Edition with Service Pack 1
SQL Server 2005 Standard Edition with Service Pack 1
I'm not a local administrator, but I have administration rights for SQL Server and Analysis Services
I'm in the Reporting Services' system administrator and system user groups
I can access http://localhost/Reports, but not http://localhost/ReportServer
I have access to the directory (incl. subdirectories) MSSQL.2, but not to MSSQL.1MSSQL and MSSQL3Reporting Services
I can't run the Reporting Services Configuration Tool (see http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1565766&SiteID=1)
I can't connect to Reporting Services in SQL Server Management Studio
My question is (as I have already mentioned in the beginning): what are the minimum rights the IT administrator has to assign to my user so that I'll be able to deploy reports? Giving me local administrator rights is not possible.
Thanx in advance and kind regards,
Gerald
Update:
In the meantime I have found out, that I'm most probably not a member of the Publisher role. But although I am in the System Administrator role I cannot assign myself to this role. When going to http://localhost/Reports the required links are just not visible. Is this because I'm not a member of the groups SQLServer2005ReportServerUser$... and SQLServer2005ReportingServicesWebServerUser$... ?

Hi all,
What are the minimum permissions required by the SQL Server 2005 Upgrade Advisor (UA)? I could not find it in the documentation.
Obviously being a local Administrators Windows group and a member of sysadmin SQL Server role will do the trick.
But will being a member of only the sysadmin SQL Server role be enough? I know that the UA does want to read the registry.
Running it under just sysadmin generates the following type of errors:
Database Server
PreUpgrade
Requested registry access is not allowed.
WINSOCKPROXY
Database Server
PreUpgrade
Requested registry access is not allowed.
FTUNSIGNEDCOMPONENTS
Database Server
PreUpgrade
Requested registry access is not allowed.
NETPROTOCOL
Database Server
PreUpgrade
Requested registry access is not allowed.
FTMULTIPLEINSTANCES
Database Server
PreUpgrade
Requested registry access is not allowed.
INVALIDNAMEDPIPE
Database Server
PreUpgrade
Requested registry access is not allowed.
FTCOMPONENTREG
Database Server
PreUpgrade
Requested registry access is not allowed.
FTACCTPASS
The issue then is whether these are significant or not. If the UA is only reading the registry to determine if SSAS, DTS, etc is installed then that is not important. But if it is affecting the end result because it cannot read critical information from the registry that is another matter.
TIA

I would like to have my developers responsible for deploying their SSIS packages to the Test/QA environment. I tried granting access to several of the stored procedures in msdb and the sysdtspackages90 table. The only thing that seems to work is granting sysadmin priviliges. Is there a server or database role that will grant the appropriate access? thanks

I have a Windows NT group that is used to delegate certain database responsibilities to other members of staff and I am trying to grant permissions for the members of the group to be be able to establish database mirroring sessions, as in run the following:
ALTER DATABASE <database>
SET PARTNER = 'tcp://principal_server.domain.com:port';
Although the group has db_owner role membership to the user database which grants the ALTER permission on the database, the following is being generated in the error log when they get to this step on the intended Mirror instance after restoring the database correctly in preperation:
SqlDumpExceptionHandler: Process 59 generated fatal exception c0000005 EXCEPTION_ACCESS_VIOLATION. SQL Server is terminating this process.
* *******************************************************************************
*
* BEGIN STACK DUMP:
* 10/29/15 11:16:15 spid 59
*
*
* Exception Address = 00007FF9A6AF838C Module(sqlmin+000000000003838C)
* Exception Code = c0000005 EXCEPTION_ACCESS_VIOLATION
* Access Violation occurred reading address 00000000000000D8
* Input Buffer 210 bytes -
* alter database <redacted> set partner = '<redacted>';
As you can see, the statement is denied to the user. There are no issues with the database as I am able to run the same query successfully using my own sysadmin account after the failed attempt. What other minimum permissions the group might need to successfully enable them to setup a mirroring session?

I'm making a copy of some tanles between 2 servers.
Server 1 requires a sql login
Server 2 is using Windows Auth.
I have a user on server 1 named "odbc" able to log in.
however my copy task fails, when I drill the error, it's lists the first user in server 1 alphabetically as the failed login???? but in my dts I am specifying the "odbc" user and password.
I think I have a permissions problem on server 1. So my Question, what minimum permissions does user "odbc" need to copy a table?
On server 1 I can copy from northwind to server 2 just fine..but any other db on server 1 causes the weird failure with the wrong username.
Any Ideas? I am not a DBA obviously :)
Thanks,
Carl

Hi There
The backup database permission seems to only be at a database level , grant backup database and db_backupoperator role only exist at a database level.
However i want to permission to a user to backup any database, and he must not be a sysadmin. I cannot find a server level role that can backup databases.
How can i do this? There are alot of database so granting the permission for every database seems a waste of time, also one would have to remember every time a new database is created to grant this permission.
There must be a way to do this at a server level?
Thanx

Hi Folks,
I have the following Problem:
( not simular to
http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=101916 )
In one Table ( Objects ) exists an Id to my internal Security Tables, where the combination of many Features together results in, which Data the user could see.
Today, i use only one SQL Account and the Security ist solved in my Application,
In an SP is a where Clause generated, every SQL Statement is extended whitch this where clause.
This work fine, but everyone with SQL User and PW could see everything this the Query Analyser or Management Studio.
The perfect solition could be:
Several Usergroups should have Access to my DB.
Only a few Views / SP where execuable for these Usergroups.
The Application calls alway the same View / SP an depending on the Login the Data ist filtered in the right way.
Is ist possible to filter a view with dynamic SQL ?
2.nd Question:
Is it possible to restrict Users / roles depending on the Network IP Address / Network Mask ?
The Security Problem only exists, when Users with VPN are connecting, internal Users always have full access.
Thanks an greeting from Germany,
Markus

I am attempting to create a view only user in Report Manager which can only view and run reports from a single directory. I have the following configured:
Active directory Group: DomainReport Users - Group Scope: Global; Group Type: Security; Member of: <none>
Active directory User: DomainReportUser - Member of: DomainReport Users group
Default web site Reports virtual directory: Directory security: Integrated Windows Authentication only
Default web site ReportServer virtual directory: Directory security: Enable Anonymous Access (user: domainadministrator) & Integrated Windows Authentication
Report Manager
Site Settings->Item-level roles: New role: Report Viewer; view folders and view reports only items selected
ReportFolder(Report Manager folder with reports): Properties->Security: Added DomainReportUser with Report Viewer role
When I go to my Report Manager site (e.g. http://url/reports) I get the Windows security form, in which I enter the DomainReportUser credentials. However, after I log in I have full rights to all folders and functions of Report Manager, as if I logged in as BuiltinAdministrator.
At what level of security is this breaking down? As far as role-based, I believe DomainReportUser should only have access to limited resources of Report Manager when logging on. What is allowing him to have Content Manager control of Report Manager? Is there a better way to set up a "view reports only" user access to Report Manager?
Thanks

Posting again in hopes that someone has a solution..
I've set up a sales report that is by territory. Two tables one of which has
sales detail records and another table with Sales Rep info, including territory and
login.. The two tables are joined by state. What I need to be able to do is schedule
this report to run on Reporting services(Already setup) and only allow the reps
to view a snapshot, don't want anyone executing the report again. Additionally,
I need them to only see the territory that they are responsible for. Does anyone
have a solution for this.

Re: SQL Server 2005
Does the xp_cmdshell proxy account need admin-level permissions on the server?
The reason I ask this is because I keep getting "Access is Denied" errors when trying to run this command as a non-admin:
master..xp_cmdshell dtexec 'some package'
The 'some package' has an "execute process task" which calls a batch file on the server.
If the proxy account is NOT a local admin, the "execute process tasks" fails with an "Access is Denied" error.
If the proxy account is a local admin, it executes fine.
We have given "Everyone" FULL CONTROL of all the folders that are affected by the batch file, and it still does not work.
I am out of ideas at this point. It just does not work unless it's an admin.
Are we missing something here?

Hey,
I have 3 columns in a table Ex:
Select Column1,Column2,Column from TableName
No. 1. Person A should have permission to read values only (Column1, Column3 of the table) -
2. Person B, should have permission to read only (Column 2).
Here my question is , I have to write one single stored procedure to statisfy both conditions. Which means, if person A execute this stored procedure , he shoud get only column 1 & 3 values . similarly other person b should get column 2 value. Ex:
Column 1 - Empid
Column 2 - SSN (Only for Top user display)
Column 3 - Join Date
Person A & B as a SQL or Windows login
Thanks

Hi Experts,
Hi experts,
I have a BI Reporting scenario, wherein i have to fetch Reports from analysis Services.
when the user tries to access a report, he should be validated uisng the Windows Authentication ID, and only data specific to that user should be display.
I am not sure if this user authentication is to be done on analysis Services/reporting services.
Any suggestions/pointers would be highly appreciated.

I need to secure a datawarehouse table at the row level based on 1 tomany keys on that table. A user should only see the rows they haveaccess to. I need to be able to figure out which rows they have accessto using a single sql statement and it cannot be dynamic SQL or astored procedure (this is a limitation based on the reporting tool weuse).The conditions can be any combination of "and" and "or" operators. Ihave seen posts (and actually have three of his books) by Joe celkodescribing disjunctive canonical form. If not familiar please clickthe link below.http://groups.google.com/group/comp...db6abcfa6209d2fA rules table in disjunctive canonical form looks like it mightpotentially be a solution, but I can't figure out how to use it acrossmultiple keys.Here ia an example of what I am trying to do including current tablestructures and sample data. I cannot really change the generic_facttable schema, but the security cross reference table can be modified oraditional tables added.CREATE TABLE generic_fact (generic_fact_key int NOT NULL ,salesrep_key int NOT NULL ,product_key int NOT NULL ,customer_key int NOT NULL ,sales_amount decimal(18, 0) NOT NULL ,CONSTRAINT PK_generic_fact PRIMARY KEY(generic_fact_key))GOinsert into generic_fact values(1,1,10,20,45)insert into generic_fact values(2,1,10,21,90)insert into generic_fact values(3,1,11,22,17)insert into generic_fact values(4,2,10,20,32)insert into generic_fact values(5,2,13,25,6)insert into generic_fact values(6,2,12,24,56)insert into generic_fact values(7,3,11,34,75)CREATE TABLE security_cross_reference (cross_ref_key int NOT NULL ,user_key int NOT NULL ,security_type varchar (50) NOT NULL ,security_value int NOT NULL ,security_operator varchar (20) NOT NULL ,CONSTRAINT PK_security_cross_reference PRIMARY KEY(cross_ref_key))GOinsert into security_cross_reference values(1,1,'product',10,'or')insert into security_cross_reference values(2,1,'customer',21,'or')insert into security_cross_reference values(3,2,'customer',20,'and')insert into security_cross_reference values(4,3,'salesrep',3,'and')insert into security_cross_reference values(5,4,'salesrep',1,'and')insert into security_cross_reference values(6,4,'customer',22,'and')insert into security_cross_reference values(7,4,'product',11,'and')So based on the data in the security cross reference tableUser 1 can see sales for customer 21 or product 10(generic_fact table rows that have generic_fact_key values of 1,2,and4)User 2 can see sales for customer 20(generic_fact table rows that have generic_fact_key values of 1 and 4)User 3 can see sales for salesrep 3(generic_fact table rows that have a generic_fact_key value of 7)User 4 can see sales for salesrep 1 and product 11 and customer 22(generic_fact table rows that have a generic_fact_key value of 3)Does anyone have any ideas on the best way to do this?
