Replication Security

Oct 16, 2007

I've setup transactional replication with pull subscriptions. All my subscribers AND my publisher sits on its own domain. Is it still possible for the subscribers to access publications using Windows accounts? If so, is the setup process different from the process for setting up publishers and subscribers on the same domain?

Thanks.

Replication Security Help Please...

Jul 10, 2006

Hello,

I am being told that my SQL server can no longer use a domain account to do replication cause it is a violation of SOX codes... So here is my question to ease my pain....

I believe that I can run the SQL server service under [local system account] with no issues but what about the SQL server agent service??

It needs rights on all the servers right??

I have found where you can configure replication to use sql authentication but then I can use snapshots...

any help would be appriciated...

oh.. I use transactional and merge if that makes any difference.

Http Replication Security Error

Aug 26, 2005

what is it supposed to mean when the sync fails and just says "a security error occurred". i verified i can view the .dll from Internet Explorer and view the share from the workstation. i gave up on the normal replication because it kept saying access was denied when it tried to download any of the files in the share... i granted access to 'everyone' for all the files and folders in that share but that didn't help.

SQL Security :: Encryption In Case Of Replication

Nov 23, 2015

I am using SQL server 2012 Management studio and I have some confidential data on publisher which is being replicated to subscriber and i want to revoke permission for decryption at publisher end which is only possible using Asymmetric key as it allows only private key to decry-pt the data. But problem which i am facing is,we can not take backup of asymmetric keys which i could restore at subscriber. I do not want to share the private key password with sender. Is there any way to achieve it?

SQL 2012 :: Security For Web Synchronization (Merge Replication)?

Feb 8, 2015

I am trying out merge replication and using web synchronization.However, I am worried that I am missing something because the way it is set up, it strikes me as a bit too insecure.

According to the best practices and security articles on Technet, I am given to understand that:

The SQL Replication Listener (read: the application pool account that will be running the replisapi.dll) has to be the db_owner to both distribution and publisher and be on the PAL list. Windows authenication should be used. That means the merge agents wouldn't need to know the password for those logins.

The basic authenication can be used (with SSL) to authenicate into a Windows user account to then connect to the replisapi.dll.

Here's the rub - I assumed that all I needed was a basic no-rights user account to be then given the execute permission on the replisapi.dll & read permissions to kick off the process. When I browse to the replisapi.dll and authenicate using the no-rights user, I get the expected "SQL Server WebSync ISAPI" message. But when I then run the merge agent, it fails saying that login to the distribution failed for the no-rights user. If I use the application pool's account, then I am able to run merge agent successfully.

But that means I am now looking at storing the password to the application pool account on client. I might have had missed a crucial step to ensure that the logins to the distribution & publication databases are done using the application pool account, not the user authenticated via IIS basic authentication?

Replication In Clustered Environement - Security Issue

Nov 16, 2007



Hello,

Not sure if this question belongs here in the Setup & Upgrade section but here is the problem.

When installing replication in a non clustered environment, the Sql replication jobs run fine with the windows login provided (this login has access to the snapshot folder and has the proper roles. All the log reader, distributer and subscriber agents work fine)


When installing replication in a windows (MS) clustered environment, the agents running under the same login and same privilages dont work. It seems like there is something wrong with the proxy account and the ability of sql to access disk resources using this account. The only workaround is to go to the agent jobs, change the login under which they work from the proxy account to an actual windows account.

Has anyone come across this issue? I am forced to use the sql agent account and running the replication agents under way more privilages than I would like to.

TIA

SSRS -- Security Filter And Model Item Security Setting

Jul 31, 2007



Hi,


I have posted this issue for a week, haven't got any reply yet, I posted it again and desperately need your help.


The article http://msdn2.microsoft.com/en-us/library/ms365343.aspx says:
Model Item Security can be set for differnt security filters, but when I use SQL Server Management Studio to set Model Item Security, it seems "Permissions" property surpass "Model Item Security" property. -- My report server is using Custom Authentication.



For example, in "Permissions" property of the model, if I checked "Use these roles for each group or user account" without setting any user or group, no matter what users I added to "Model Item Security" with "Secure individual model items independently for this model" checked, NO one user can see the model on report manager and report builder;

in above situation, if I added "user1" and gave role such as "Browser" role to "user1" in "Permissions" property, if I checked "Secure individual model items independently for this model" in "Model Item Security" property, even I did NOT grant "user1" to root model and any entities under the model, the "user1" is able to access the model and all entities in report builder.



My question is on the same report model, how to set "AdminFilter" (empty security filter) for administrator permissions and set "GeneralFilter" (filtered on UserID) for general user based on their UserID?


The article also says:

"Security filters are always applied, even for users who have Content Manager or Administrator permissions to the model. To allow administrators or other users to see all rows of an entity on which row-level security is defined, you can create an empty security filter (which always returns True) and then use the filter to grant those users access to all the rows."



So I defined 2 filters "GeneralFilter" and "AdminFilter" for "Staff" entity for my report model "SSRSModel", I expect after I deployed the report model, the administrator users use report builder to build reports with all rows available, and the non-admin users can only see rows based on their UserID.



I can only get one result at a time but not both:

either the rows are filtered or not filtered at all, no matter how I set the "SecurityFilter" for the entity: I tried setting both "AdminFilter" and "GeneralFilter" for SecurityFilter at the same time, combination of "DefaultSecurityFilter" and "SecurityFilter", or one at a time.



Your help is highly appreciated!

Setup Of Security / Integrated Win Security On Vista

Jul 6, 2007

I have Sql Server Express installed on Vista (service pack 2)

I have Visual Studio 2005 with an application that I'm trying to access it with within a WCF service.



The login ID of the service is added to the database.

The database has remote access turned on.

The ID is granted access to all databases within the server.

The thread is being set with WindowsProvider and the services set their thread to WindowsProvider.

The dataserver is set with using Windows Authentication for security.



When I open my connection to the database, though, it reports the typically useless message that the connection is not allowed and that the server may not allow remote connections.



How to I get past this? I've done everything right.

Transport Security Vs Dialog Security

Aug 3, 2006

In an environment where there are many initaitors speaking to a central target with frowarders in between, from what i can understand this best policy is to disable encryption on the endpoints, since dialog encryption will be enforced this is all that is really required, is this correct.

If the endpoints used encryption the message would need to be encrypted and decrypted at each forwarder resulting in slower perfromance, where as dialog encryption would only encrypt at the sender and decrypt at the target, so is this the best way to go?

Secondly is it best practice to open a dialog initally and send messages over this dialog for years never ending the conversation? This way the services only have to authenticate eachother once, if there are no reboots etc that is of course.

I would think performance wise sending each message and ending the conversation each time is a much greater overhead ? So would it be best practice to keep dialogs open and keep sending messages ?

Initally when i was learning service broker i thought that one must send a message and end the dialog until the next message, but i think the other way is the best option ?

Is this correct ?

Thanx

Dialogue Security Vs Transport Security

Feb 19, 2007

Hi

I'm designing a distributed application where I will have SQL Server 2005 distributed databases replicating data to my central hub which is again a SQL Server 2005 database using SQL Service Broker. Data will be sent from the central hub to the distributed sites and vice versa. I need to authenticate the communication and also secure the communication by encrypting the messages. Which security shall I use? Where do I configure the type of security being used? What is the difference between transport security Vs dialogue security - Full security model?



Thanks

Replication Issues After A Database Restore - Unable To Drop Or Create Transactional Replication

Sep 13, 2007

Hi,I have transactional replication set up on on of our MS SQL 2000 (SP4)Std Edition database serverBecause of an unfortunate scenario, I had to restore one of thepublication databases. I scripted the replication module and droppedthe publication first. Then did a full restore.When I try to set up the replication thru the script, it created thepublication with the following error messageServer: Msg 2714, Level 16, State 5, Procedure SYNC_FCR ToGPRPTS_GL00100, Line 1There is already an object named 'SYNC_FCR To GPRPTS_GL00100' in thedatabase.It seems the previous replication has set up these system viewsSYNC_FCR To GPRPTS_GL00100. And I have tried dropping the replicationmodule again to see if it drops the views but it didn't.The replication fails with some wired error & complains about thisviews when I try to run the synch..I even tried running the sp_removedbreplication to drop thereplication module, but the views do not seem to disappear.My question is how do I remove these system views or how do I make thereplication work without using these views or create new views.. Whyis this creating those system views in the first place?I would appreciate if anyone can help me fix this issue. Please feelfree to let me know if any additional information or scripts needed.Thanks in advance..Regards,Aravin Rajendra.

SQL Express Replication And Problems Accessing Data After Replication

Jul 28, 2006

Hi,

I have a VB.net app that access a SQL Express database. I have transactional repliaction set up on a SQL 2000 database (the publisher) and a pull subscription from the VB.net app. I use RMO in the VB app to connect to the publisher. My problem is I am getting some strange behaviour as follows

- if I run the app and invoke the pull subscription it works fine. If I then close my app and go back in, I can access my data without any problem

- If I run the app and try to access data in my SQL Express database it works fine. I can then close the app, reopen it and run the pull subscription it works fine

however.......

- if I run the app, invoke the pull subscription (which runs fine), and then try to access data in my local SQL Express database without firstly closing and reopening the app, I get a login error

- if I run the app, try to access data in my local SQL Express database (which works fine), and then try to run the pull subscription I get a "the process cannot acces the file as it is being used by another process" error. In this case I need to restart the SQL Express service to be able to run replication again.

I get exactly the same behaviour when I use the Windows Sync tool (with my app open at the same time) instead of my RMO code to replicate the data.

I am using standard ADO.Net 2 code to access my SQL Express data in the app and closing all connections etc

Any advice appreciated !

Thanks
Ronan

How Do We Add A New Column To A Merge Replication Article, But Specify It As Not For Replication?

Aug 30, 2007

Hi all,

I know that adding a column using ALTER TABLE to add a column automatically allows SQLSERVER 2005 to replicate the schema changes to the subscribers, however, I would like to add a new column to an existing article that is being used for merge replication, however, I don't want this column to be replicated. Re-initialising the subscriptions is not a option. Help would be appreciated.

I am using SQLSERVER 2005 (SP1).

Replication :: Transactional Replication Removal Sequence

Sep 2, 2015

I have been researching on the proper steps or sequence to follow to completely remove SQL Server 2012 Transactional Replication.  I have read articles about using SSMS as well as using replication stored procedures and some procedures use SQLCMD or just regular TSQL executed in SSMS.  I have also read articles where people said all you really need is connect to the Publisher instance, find the publication you want to remove and choose "Delete" and everything will be taken care of behind the scene. I have three SQL servers that participate in transactional replication.  SQL-P (publisher), 

SQL-D (distributor) and SQL-S (subscriber).  Do I need to connect to the distributor instance and the subscriber instance when removing transactional replication or is it just really connecting to the publisher and click delete on the publication? I want everything gone including any metadata, systems tables, distributions db and any other replication objects created during the initial configuration.

DB Replication Or Table Replication Via Triggers?

Apr 17, 2007

Hello everyone,I am involved in a scenario where there is a huge (SQL Server 2005)production database containing tables that are updated multiple timesper second. End-user reports need to be generated against the data inthis database, and so the powers-that-be came to the conclusion that areporting database is necessary in order to offload report processingfrom production; of course, this means that data will have to bereplicated to the reporting database. However, we do not need all ofthe data in the production database, and perhaps a filtering criteriacan be established where only certain rows are replicated over to thereporting database as they're inserted (and possibly updated/deleted).The current though process is that the programmers designing thequeries/reports will know exactly what data they need from productionand be able to modify the replication criteria as needed. For example,programmer A might write a report where the data he needs can beexpressed in a simple replication criteria for table T where column X= "WOOD" and column Y = "MAHOGANY". Programmer B might come along amonth later and write a report whose relies on the same table T wherecolumn X = "METAL" and column Z in (12, 24, 36). Programmer B willhave to modify Programmer A's replication criteria in such a way as toaccomodate both reports, in this case something like "Copy rows fromtable T where (col X = "WOOD" and col Y = "MAHOGANY") or (col X ="METAL" and col Z in (12, 24, 36))". The example I gave is reallytrivial of course but is sufficient to give you an idea of what thecurrent thought-process is.I assume that this is a requirement that many of you may haveencountered in the past and I am wondering what solutions you wereable to come up with. Personally, I believe that the above method isprone to error (in this case the use of triggers to specifyreplication criteria) and I'd much rather use replication services tocopy tables in their entirety. However, this does not seem to be anoption in my case due to the sheer size of certain tables. Is thereanything out there that performs replication based on complexprogrammer defined criteria? Are triggers a viable alternative? Anyalternative out-of-the-box solutions?Any feedback would be appreciated.Regards!Anthony

Merge Replication Set Off Transactional Replication

Oct 9, 2007

I am working on bringing our disaster recovery site to be a live site. Currently we replicate to one of out servers (server B) with merge replication (from server A). Server A also does one way transactional replication form some table to several other servers including servers at the DR site.

This setup is not going to be fast enough for what we need so I am wondering if a table is receiving merge replication will the merge updates also replicate down the transaction path??

Example...
Server B update a row and merges to Server A. With this update them replicate (via transactional) to Server C??

thanks...
