Force Encryption Login Not Working
Aug 8, 2007
Hi,
i've enabled the certification authentication login i use SQL 2K5 ENT
my problem is like that: in the client network utility i check the Force protocol encryption and connect
to the server the client can't connect because he doesn't have the certificate install on his machine which it's OK.
the problem is when i remove the Force protocol encryption on the client he connect successfully without the
certificate install on his machine or any thing.
i double check that on the server i've YES on the Force Encryption in the protocols For MSSQLSERVER.
why is that???
THX

Hi,
I am at a loss here, unless I misunderstand the whole point about server encryption. My 2005 SQL server has a certificate from a trust CA, I have turned on the 'force encryption' flags on the server. My understanding is any client will be "force" to connect with encryption?? I found out that unless I turn on encryption on my clients, the server will allow connections without the requiring encryption. Am I missing something here? Thanks for any help you can provide.

I want to configure SQL 2k5 Express so that all connections are
encrypted. I've found the documentation that gives the How-To steps,
but I don't see the SSL option in the Network Configuration.
Is this possible with the Express edition?
Do I need to do something special with the installation?
Thanks,
OldSam

I am connection to a SQL server that has force protocol encryption checked. From my ASP.net application, specifically in my connection string, what parameter do I need to use to take advantage of this encryption?
Thanks!

I have a SQL Server 2012 Standard and needed to fulfill a requirement to set Force Encryption on the Server with a DoD Certificate.
I will be altering my client connections to use Encrypt=True; TrustServerCertificate=True (The client is a .Net Web Application).
The OS is where SQL Server 2012 Standard resides is Windows 2008 R2 DataCenter Service Pack 1 64-bit.
What I am needing to know is where do I get the DoD Certificate from? and Do I just install it on the server where SQL Server resides?

I would like to force only certain users on certain databases to use encrypted connections for accessing our 2005 SQL Server. I've found a clunky way to do it, via registering a login event notification and using the kill statement. However, that's ugly, and I don't think there is any guarantee that the event will always fire before an evil client could get off a few evil commands. Is this supported, or is the only supported feature the forceencryption option, which is server-wide?

I have a customer who is looking to encrypt their applications connection to the back-end SQL server. I've gotten a valid certificate for the server from a trusted CA, and it's installed on the server (shows up in Personal certificates in the Certificate MMC when selecting the computer) and I can choose it in the drop down on the certificates tab of the SQL Network protocols properties in Configuration Manager.
Now, my question: If I select the certificate but do NOT enable the "Force Encryption" option, the client will be able to request encryption on their end, and the connection will then be encrypted. If the client (other applications) do NOT request encryption, they will still be able to connect, but their connection will be un-encrypted. URL....
Lastly, I could've swore I had found some information indicating that some methods of establishing a connection to SQL can fail when Force Encryption is enabled, as the method doesn't support SSL encryption.

I am accessing a SQL2005 Express SP1 Server via TCP/IP (all machines fully up to date with windows update). For ease of configuration the Server IP is mapped to an Alias in Native Client Configuration Manager. On the Client Force Protocol Encryption is set to Yes and Trust Server Certificate is set to No. The clients are accessing the DB via SQL 2005 Management studio express and Ms Access 2003 (an access adp front end to the sql database).
As a test i turned off force encryption on the server. A Network trace shows no encryption! Turning on force encryption on the server corrects this.
As a further test I configured the server with a certificate the client doesn't trust. No error is generated by the un-trusted certificate! The only way to generate the certificate error is to enable encryption in the connection properties of each application. Why isn't the Native Client Configuration Manager utility enforcing this???
This brings me on to a second (off-topic problem). In my access adp file, if I enable €œuse encryption for data€? advanced option under the database connection dialog all works as expected (encryption + certificate verification). However, I am programmatically updating the connection in VBA
Application.CurrentProject.OpenConnection "Provider=SQLOLEDB.1;Data Source=AliasName;Use Encryption for Data=True;..."
If I do this no encryption is enabled!!! Access seems to just ignore the encryption statement.
Has anybody got any ideas as to why either of these issues are occurring or if there are any workarounds?
Thanks
Stuart

I set up odbc to link to sql express from access 2003, using sql authentication to force a login, and did not click 'save password'. when i open up access again, and open table, it goes right in without a login. How can I set so it does a login, at least each time Access opens?

How can you force a password, from a sql login, to expire?
I would like to use the password expiration feature for sql logins in SqlServer 2005. The msdn document provides example code for SqlClient SqlConnection.ChangePassword like in Bob Beauchemin's book. http://msdn2.microsoft.com/en-us/library/system.data.sqlclient.sqlconnection.changepassword.aspx
There is a modify_date in the system view sys.sql_logins but that is read-only.
Thanks,
Karl

I am in a situation where I would like to use a SQL login instead of adding individuals windows login to the server. Is there a way to force a login instead of having the report server not give rights at all??
I hope that makes sense...
Thanks

Please be gentle...I am very new to working with SQL.
I have the need to encrypt my columns in SQL 2005. I have created a symmetric key 'SecureKey' as well as a secure certificate 'SecureCert'
I have ran the script to create the key and the certificate successfully. When I run "select * sys.symmetic_keys;" the key shows up...when I run "select * sys.certificates;" the cert shows up.
Here is my issue, in the security folder under my database, these two things do not show up in the appropriate folders. Also when I run my encryption scripts, I am getting an error of
"msg 15151, Level 16, State 1, Line 3
cannot find the symmetric key 'SecureKey', because it does not exist or you do not have permission"
Am I missing something?
Thanks

I currently have a login page in asp.net 2.0 linked to a SQL 2005 database table that holds the usernames and passwords. At present, I am on an "honor system" where I do have access to the passwords of the other users but would like to change it so that I cannot know what the users' passwords are. Thank goodness that there is no personal information within the pages and the logins were created to keep a log of who logs in and what not. However, I would like to soon hold more personlized information, hence the need to encrypt each user's password even from myself.
I have read up on Symmetric Encryption for SQL 2005 but I would like to know if there is anything else available, any good proven methods that someone else has already tried.
Also, while testing out Symmetric Encryption, I noticed that I have to supply the encryption password for the decryption. However, if I know what the password for the encryption/decription is, does it not defeat the purpose of having the encryption at all, in terms of the "Admin" having access to sensitive information? Just curious if I understood the concept correctly or not.
Thanks in advance to all.

Ok.. I have a web site I am developing in Visual Studio 2005. Its VB based with SQL Server 2005 as the backend. IIS 6 is the web engine and all of this is running on a Windows 2003 Server.
Here is the problem.. I have a form that authenticates a user and then redirects them to another page. The redirection is not working. All I get is 'Your login attempt was not successful. Please try again.' So I decided to trouble shoot a little and I added a Forgot your password control and a Sign up for new account control to the page as well. When I do the Forgot my password it sends me the username and password in an email, but it just refuses to accept them.
If I use the sign up for a new account control it actually lets me into the redirect page but if I log out and try to get back in it fails. Its crazy and if driving me out of my mind.
If someone wants to help me out I would appreciate it. I have been racking my brain over this for too many days.
Thanks in advance...
Mark
Ps. - I have read every thread and tried just about everything regarding this issue. It has to be something stupid and simple that I am overlooking.

I notice when I copy an SSIS package 'A' to a new package 'B', the new package 'B' will generate a "login failed for user" message in the data flow components. To copy I "save copy of Package 'A' as."
Some config info:
Package ProtectionLevel = EncryptSensitiveWithPassword
Connections are Data Sources
Connection strings with password are stored using PackageConfigurations to an SQLServer table. I've verified Package 'A' is in fact using the config table (e.g. it is not using a password or user stored in the package)
Data connectios are all SQLServer Native OLE DB Client
The account is an SQLServer account (not integrated security)
The original Package 'A' works flawlessly and I get success when I test the connections in Package 'B'.
But executing package 'B' I get: The error message I get is: [Connection manager "MyConnection"] Error: An OLE DB error has occurred. Error code: 0x80040E4D. An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80040E4D Description: "Login failed for user 'dwuser'.".
Does anyone know why this would occur and/or how to work around it? I saw another thread where a potential workaround is to create a new data flow task and copy all the data flow components to that task. That won't work well for us because the data flow is moderately complex and when you copy and paste it, SSIS completely re-orders the layout.
This is a typical data warehouse ETL setup where there is a master package that executes child packages (e.g. 'A', and 'B' mentioned above) that each perform the ETL for a specific dimension or fact table.
Thanks for any help,

I have created two user defined functions for encryption and decryption using passphrase mechanism. When I call encryption function, each time I am getting the different values for the same input. While I searching a particular value, it takes long time to retrieve due to calling decryption function for each row.
best way to encrypt and decrypt using user defined functions.Below is the query which is taking long time.
SELECT ID FROM table WITH (NOLOCK)
                    WHERE dbo.DecodeFunction(column) = 'value'
When I try to use symetric or asymetric encryption, I am not able to put "OPEN SYMETRIC KEY" code in a function. So, I am using PassPhrase mechanism.

Been looking through the forums for a solution to this problem.I already tried granting access through statements such as:exec sp_grantloginaccess N1'machineNameASPNET'But they don't seem to work.. i vaguely remember seeing somewhere a DOS command line statement that grants access to the ASPNET_WP and that fixed my problem before on another computer.. but this is a new computer and i forgot to write down the command.Can anyone help explain and propose a solution to my problem.

hi,
so i have a new box and I'm trying to get my websites and SQL Server 2005 Standard Edition working on it, but the pages give me the following error when I try to load them:
"Cannot Open Database "XXXX" requested by login. The login failed. Login failed for user 'xxx'"
Everything seems exactly the same settings and user-wise from my old box to my new one, but nevertheless everything I've tried gives me the same error.
I've tried creating new users in SQL Server and giving them appropriate permissions to my database. I've even tried just using the built in 'sa' account. Nothing seems to change the error, except when I give it the incorrect password then it just says 'login failed'
This leads me to believe that i'm successfully logging into the SQL Server, but it doesn't want to give me access to the database I'm requesting access too. But "apparently" the account i'm using should have access to the database. If nothing else the 'sa' account should, but that didn't work either.
I'm stumped. Any ideas?

hi
I had a view in which I did something like this
isnull(fld,val) as 'alias'
when I assign a value to this in the client (vb 6.0) it works ok in sql2000 but fails in 2005.
When I change the query to fld as 'alias' then it works ok in sql 2005 .
why ?? I still have sql 2000 (8.0) compatability.
Also some queries which are pretty badly written run on sql 2000 but dont run at all in sql 2005 ???
any clues or answers ?? it is some configuration issue ?
Thanks in advance.

Hi All
Forgive my ignorance. I have been told you cannot run a force restore without SQL Agent running? Is that so?
Also, is it possible to execute a force restore from a command line. If so, how would you go about do this.
I ask these questions because recently our database and MSBD files became corrupted and couldn't restore them in the normal way. Had to manually rebuild MSDB file.
Thanks

I have a script or SP that takes a very long time to performmultiple tasks, and after each one there is a PRINT statementthat shows the time and what was just accomplished, to help memonitor what's happening and estimate how long it will take.In a script, I can put a GO after each PRINT to cause the outputto appear immediately, but that's not possible inside an SP.Instead, it seems the output goes to a buffer, and the bufferis only output when a PRINT causes the buffer to become full.Sometimes there is a long delay before the buffer fills. Isthere a way other than GO to cause immediate printing? (Iguess I could just use longer messages, and fill up thebuffer with every one, but that's not very elegant.)Thanks,Jim GCountrywide Home Loans

I've a complex stored procedure, that makes a lot of insert, update,delete and so on.I would like to make some commits durint this sp, but of course theyare not "real" commit because who call the sp could decide for arollback.But I know that this commit has to be real. In fact, the transactionlog grows really too much during the execution.Is there a way to force a commit durint a sp ?thank you very much!

Hi,
My data flow has several transformations:
1. Search an employee, if the employee already exists, update it, otherwise insert it.
2. Once the new employee is created, i have to get its id (with another search transformation )to update another table with it. This id is an autonumeric , thats the reason i have to get it once the record is inserted.
At this momment this second search transformation to get the assigned id for the new reacord doesnt find any employee... i suppose its because these new data is not commited in the database....
the question is, Its possible to force a commit?
Thanks!

Hi everybody,
I would like to know if there would be any special way to force drop a database from an ASP.NET page.
When I try to do it in the normal way, it gives me an exception like: Cannot drop the database 'xxxxxxx' because it is currently in use. I'would have to wait until there is a timeout.
In fact that database can be accessed from another pages, but I want to know if I'd be able to force drop database even when another pages are using it.
Thanks in advance
