Custom Security Extensions For SQL RS 2005

Apr 12, 2007

Hi,



I'm having a lot of trouble trying to set up a custom security extension with Reporting Services 2005. Following the VB example from McGraw Hill Osborne (http://www.mhprofessional.com/product.php?cat=112&isbn=0072262397&cat=112), I've compiled the .dll for the extension and made the changes to the ReportManager and ReportServer .config files. After I reset IIS and return to the RS website, it displays "The report server has encountered a configuration error..." and I get a message in my System Event log:



The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID
{BA126AD1-2166-11D1-B1D0-00805FC1270E}
to the user MYMACHINEASPNET SID (S-1-5-21-1708537768-839522115-1343024091-1005). This security permission can be modified using the Component Services administrative tool.



Wondering if anyone else has had similar trouble and how did they get around it?

SSRS Custom Security Extensions: Copying Between Machines

Apr 24, 2007

Hi,



Have compiled and set up a custom security extension for SQL Reporting Services on my local machine and got it working. However, I'm trying to copy the extension across to a different server. So far, I've tried copying the updated dlls straight from my machine to the server and making the relevant changes in Reporting Services .config files (rsWebApplication.config, rssvrpolicy.config, etc)



Initially, the Forms authentication redirects to a login page as expected. However, when we try to submit a login name and password from this login page, it throws this error message:



"Invalid URI: The format of the URI could not be determined."



Is copying the dlls straight across a bad idea?



If anyone has encountered a similar issue, do you know if there are there certain things I should be checking for, or have missed, when trying to replicate a custom security extension on a different machine?



(FYI, the original server where it worked was Windows XP SP2, new server is Windows Server 2003 SP1)

Reporting Service 2005, Custom Security Extension Failed.

Mar 10, 2006

Hi,

I am trying the get the custom security extension samples to work on my machine. I have installed everything according the sameple help file. However, i am getting a "Authentication Ticket is not issued by LogonUser." error after I attempted to log on to the report manager thru UILogon.aspx page. I already created an admin user. Upon a closer inspection, I realized that the authentication went thru okay, however, the authentication Ticket Name contained in the "RSAuthenticationHeader" has a duplicate value of "sqlauthticket, sqlauthticket". So apparently, the report server added this value twice to the response header. Has anyone seen this error before? How would you fix it? Also to bypass this error, I parsed out the header and take the correct auth ticket name, now report manager just redisplays the logon page and not letting me thru. Has anyone have seen that before? I am running in Win 2003 server, IIS 6, .NET 2.0 and SQL server 2005 enterprise version.

Thanks for the help,

Eric

More Custom Security Questions

Jun 25, 2007

Still working on custom security
Since I can't get a name of file (path) from within CheckAccess method it becomes somewhat useless. Is there a way to maybe overload GetPermissions or Policies methods? Or maybe CreateReport method so that I can include some custom code there? Is there an example of something like that?

I wish the catalog tree was transparent to Authentication extension, I don't see a point in acl for a custom extension, all I want is names and I can build on top of that. Something along the lines -




Code Snippet

public bool CheckAccess(...file...)
{
string[] permissions ;
permissions = server.GetPermissions(file);
...
Maybe I am missing something simple and I can tie everything to a security descriptor but I don't see how I can if there is no information such as name, date, modified by name and so on. All we get is principal name which is not very useful since I don't use built-in security names.

Thanks

Custom Assembly Security

Oct 3, 2007

Hello Everyone,

When I run my report from report manager, I get the following error message

Failed to load expression host assembly. Details: Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

My report uses a custom assembly. I have already done the following

1. copied the assembly in the "reportserverin" and the "common 7privateassemblies" area
2. Made the following entry in the rssrvpolicy.config

<CodeGroup

3. Added the following line to my assemblyinfo.cs file

[assembly: AllowPartiallyTrustedCallers]

Hi,

The custom security extension generates the following error, when try to access Report Manager. The specifications are as follows.
1. Its 64-bit SQL Server (Reporting Services) and installed as default instance.
2. The Report Server is accessible programmatically. I can publish, view reports without problems, but Report Manager gives an error.
3. Another instance (named instance) of Reporting Services with the same custom security extension on same server is working fine. Report Manager opens up without problems.
4. Both the instances working fine since 3 installation and configuration (3 months back). Now, only the Report Manager of the default instance is not openeing up.

Custom Security W/ Standard Edition/

Dec 28, 2006

Hello...

I am trying to verify that the ability to use the security extension to use Forms based authentication is available (or not) with SQL 2005 Standard. I have read a few books and articles that state that only the Enterprise edition will allow us to use the security extensions to customize authentication and authorization. But a few recently have told me otherwise.

Does anyone know for sure? We use Standard edition...and would like to customize our security.

Deploying With Custom Forms Security Enabled

Jul 31, 2006

I have recently enabled a custom Forms Security on my Windows 2003 Server w/ SQL Server 2005 Reporting Services. All the functionality I would expect is working properly, except for the ability to deploy to the reports server from inside my Visual Studio 2005 Reports Project.

The 'Reporting Services Login' window opens, prompting me for a username and password. Regardless of what is supplied, the window keeps reappearing, and I am unable to deploy. I am able to upload the files from within the Report Manager, but that is time consuming and inelegant.

Any help would be greatly appreciated!

Custom Security Extension: How To Give Access To Everyone

May 29, 2007

Hi All,



My application is currently integration with reporting services using custom security extension. I have my own USER and ROLE database to determine who/which role can access certain reports.

My question is how to give access a report to be viewable by everyone? I dont want to assign all users or all roles to achieve this.

The other thing that I found out is, let say I change the name one of the user/role. Because of this, the authorization will fail because the old name/role is not in the DB anymore. Is this expected? or is there a workaround it?



Your help is appreciated.



Thanks!

Integrated Security Problems With Custom Server Option

Mar 13, 2008

Ok, I need to test my webservice with the 'use custom server' option on so that I can specify a base URL that I can reference from apps on a remote machine. I have a connection string I am using to access a sql server db that has Integrated Security=true and windows login has a login for it created in the db.

However, whenever I try to call a webmethod I get this error:
System.Data.SqlClient.SqlException: Login failed for user ''. The user is not associated with a trusted SQL Server connection.

But when I call the same webmethod specifiying a sql login / pw, and not integrated security, my webmethod works.

I want to use integrated security though, please help!

Dynamic Dimension Security Limitations And Performance When Using Custom Dll (UDF)

May 21, 2008

Hi,

I've created a custom dll using ADOMD.net that takes in a few parameters (Username being one of them) and returns a set of Allowed Members to apply dynamic dimension security. Example:





Code Snippet

Security.GetSetList(UserName,1,"SQL Server")

This works fine for users with less than, say, 100 tuples/members in their set....however for users with more an error:

Error ocurred retreiving child nodes: The 'S' attribute in the 'S' dimension has a generated dimension security expression that is not valid. ...


However, if I take the same set and explicitly (ie


Code Snippet

{[S].[1],[S].[2],.......[S].[50000]}) put it in the Allowed set there's no issue!

I noticed that it takes the UDF a couple of seconds longer to return for users with a large security context. Is there a time-out parameter that controls this? Is there a limitation in the amount of members I can add via custom dll (UDF)? (Some users can have up to 70,000 members)

I should also mention that the UDF uses the StrtoSet function to convert the security context string to a set. The string can be as large as 210,000 characters. Is there a limitation on the string size that can be passed in this function?

Any assistance would be greatly appreciated.

Thanks!!

Custom Security For Reportserver With Some ISAPI Filter In Progress

May 25, 2007

hi,

I am new to report server custom security.

I face the following problem and want to ask if there is a simple way to solve.



we have already running an IS API Filter which handles the authentication for all websites. The fiter is built to secure all websites. It verfies access to URLs and authrize users against an LDAP Directory. Affer the user has authenticated he can connect to the website. The ISAPI Filter sets the LOGONUSER Severvariable so the website can do userspecific filtering.



With the same ISAPI Filter we want to secure report server.

We want to setup roles with usernames to allow or deny specific reports. (this usernames should be validated against the servervariable LOGONUser - by String Comparison).

We do not have any windows authenitcation - and do not need.

The ReportServer User Variable should return this LOGON User to allow report secific data filtering



Is this possible - and explanation how?



Best Regards,

HANNES

Custom Security Extension - Authorization Questions Using Forms Authentication

Nov 9, 2007

Greetings. I have developed our own custom security extension, implemented forms based authentication, and can authenticate from report manager, report server and sql studio. So far so good.

However, when it comes to Authorization, i'm unclear in a few areas and would appreciate if someone could help me out with the following questions. It should be noted that in the code I have granted an administrator user full access to all operations and permissions, and then tested against both an administrator user and a normal user.


IAuthorizationExtension.GetPermissions summary says

"Returns the set of permissions granted a specific user for an item in the report server database."

Inparticular, the secDesc parameter is supposed to contain the security descriptor associated with the item.

However, with our extension this parameter is always null, even if I have already granted access for a user, which is confirmed through logging in CreateSecurityDescriptor.

Through the report manager or sql studio I can see that the permissions have been created, so I can't understand why I never see them in the GetPermissions method? This then (seems to) flow through to the various CheckAccess methods, where the users are authenticated, but are not authorized to perform any operations. i.e. in report manager a user has no folders or reports available.


Is RS authorization designed around the concept that the details will always be stored in it's own database?

Ideally, we'd like to have the various roles, users and function authorizations defined in our own security framework. This is working great for the authentication aspect of the extension, but unless there is a mechanism which exposes the details of the particular authorization process (e.g. the name of the folder being viewed or report being run), then I can't see a way we can implement it. Unless i'm missing something fundamental of course!


Using Report Builder as the Administrator user (or any other user), I can see no data models available, even though I have created them via Report Manager, and I get the following exception trying to open up the list of reports:

System.Web.Services.Protocols.SoapException: The permissions granted to user '' are insufficient for performing this operation. ---> Microsoft.ReportingServices.Diagnostics.Utilities.AccessDeniedException: The permissions granted to user '' are insufficient for performing this operation. at Microsoft.ReportingServices.Library.ListChildrenAction.PerformActionNow() at Microsoft.ReportingServices.Library.RSSoapAction.Execute() at Microsoft.ReportingServices.WebServer.ReportingService2005.ListChildren(String Item, Boolean Recursive, CatalogItem[]& CatalogItems)

I have implemented a report server proxy (inherited from ReportService2005) as per the example, to pass through the authorization cookie. Any clues as to what could be wrong?

Finally, I suspect part of my problem may be in assignment of users to System Roles ("System Administrator" and "System User"), I'm not sure if these are meant only for Windows Authentication? I can see no way of assigning these roles to any of my users using Forms Authentication.

Thanks for any help or advice you can give!

Even then I continue to get this error. Any help? Is there anything else I am missing? I am using VS .Net 2005, SRSS 2005 on W23 machine.

I have been stuck here for a while now. Help is appreciated.

Custom Security Extension - Report Manager And Report Server On Different Machines

Sep 19, 2007

Hi,

I'm trying to deploy Reporting Services on an Internet-facing web server using a custom security extension (forms authentication). We will be putting Report Manager on the Web Server outside of the firewall, and Report Server on another machine inside the firewall. When testing the solution in a development environment with Report Manager and Report Server on the same box, the solution works fine.

When testing it using the Internet-facing environment described above, it almost works but there seems to be an issue with the authentication cookie that is generated. Here's what happens:

1. User enters credentials on UILogon.aspx and submits form.
2. In the code-behind, LogonUser() is called through a web service proxy and the authentication cookie is returned successfully. The code used here to set the cookie is the same code used in the Forms Authentication sample that ships with RS2005.
3. The user is redirected to Folder.aspx, and the request hangs for a while, and eventually kicks you back out to UILogon.aspx, as if it lost the authentication cookie. When doing a trace on the HTTP header, the cookie is still there.

Is there anything special I need to do to make the Report Server "see" the cookie when I have Report Manager and Report Server on different machines?

Any help would be much appreciated!

What's The Best Way To Deploy CLR Extensions To SQL Express?

Jul 5, 2006

The project I'm working on has been developed using SQL 2005 Developer Edition and VS 2005, so up until now VS has been handling the task of deploying my C# managed code stored procedures to the database.

Now it's time to deploy a beta of the product, and we want to use SQL 2005 Express, and take advantage of it's new XCOPY deployment mode which in turn means we can also take full advantage of Click Once for our software updates. The idea here is that we can deploy new or updated stored procedures in a managed DLL using Click Once, making updates presumably more simple and robust.

So the steps we need to complete at runtime are:

1. Dynamically load and access the database MDF file using SQL Express (done).

2. Enable CLR Integration for the dynamically loaded DB (done)

3. Instantiate all of the stored procedures - help!

Looking at the docs, it seems we have to execute the following SQL for each and every SP:

CREATE PROCEDURE <Procedure Name>

@inputArg2 type, @inputArg2 type, @inputArg3 type OUTPUT

AS EXTERNAL NAME <Assembly Identifier>.<Type Name>.<Method Name>

But, we're talking about literally hundreds of stored procedures that need to be instantiated here, which obviously means a lot of double-definitions and a fairly high chance of bugs creeping in.



Surely there has to be a better way?

Files And File Extensions

Mar 6, 2007

Hello.

I am attempting to document the various files that are incorporated into a reporting services project and need a more official explanation or defintion of the particular file and it's purpose. I understand what most of the files are and what they serve but would prefer to document it using Microsoft's official explanation so that we can decide which files may require that we source control them.

I have tried searching MSDN for 'file extentions',' file types', and typing in the individual .xxx extensions in to see if there is a documented definition for those files but seemed to get results that do not give me an official definition, didn't come close or were entirely not related.

.sln, .suo, .rds, .rdl, .rdl.data, .rptproj, .rptproj.vspscc, etc

Any links to the official explantion or definition of the files that make up a reporting services report project and their function/importance to the project would be appreciated.

Thanks.

Will Buffer Pool Extensions Have Benefit If Already On SSDs?

Sep 24, 2015

I am reading about Buffer Pool Extensions, and how it stores data pages on media like an SSD, to speed up retrieval in future. Would this be useless if my mdf files are already on SSD media? At most, I envisage it meaning that instead of grabbing the data from the mdf, it would grab the data from the buffer pool extension drive, but if they are both on SSD's, I'm not sure of how much return I would see.

Has any user decided to use BPE when their data is already on SSD's, and have they noticed any improvement in these cases?

So it seems to be failing at GetAuthzContextForUser


I've set up my smtp as out domain email smtp, given the accounts all the permissions I could (Even going to far as to give Everyone permissions everywhere)
Currently my IIS, SQL 2005 and reporting Services 2005 as well as my local SMTP is running on the local machine account.


I cannot seem to get it to work, or even give me a different error.

Could anybody please tell me what needs permission where and what settings I need to have set up for this not to happen.


Some extra information

I'm using Windows XP to develop on however the server where this will eventually run is Windows Server 2003

I'm using ASP.NET 2 and SQL Reporting Services 2005 and SQL 2005 with sp1 loaded

Any help would be appreciated

Data Processing Extensions On SQL Server Express Edition?

Jan 3, 2007

I developed nice reports using custom data processing extensions.  When I deployed the reports on my report server (I am using the express edition of SQL Server 2005) I was surprised to see that my reports were not rendering successfully.
 
After searching the web, I found this page listing the supported/unsupported features of SQL Server 2005 Express Edition: http://msdn2.microsoft.com/en-us/library/ms365166.aspx
 
On this page it clearly says €œThe Reporting Services API extensible platform for delivery, data processing, rendering, and security is not supported.€?
 
Is there a way to get my reports to work on the express edition?
 
If not, which minimal version of SQL Server should a buy to get it to work (workgroup, standard or enterprise)?
 
Thanks for your help.

SQL Server Admin 2014 :: Buffer Pool Extensions On Shared SSD?

Oct 8, 2015

extending the buffer pool onto an SSD drive that is shared ? For instance, if we had a mirrored system drive(The C logical partition) on SSD's, can we use the remaining space on that mirrored partition to extend my SQL 2014 buffer pool ? I understand that in this scenario, there is some competition for the I/O throughput between SQL Server's extended buffer pool and the OS. We intend to have the pagefile on a different disk, other than this specific SSD.
