Enforce Password Policy And Expiration In .NET 3.5 Application
May 22, 2008
Hello,
I am building a winforms .net 3.5 application which connects to a SQL Server 2005 database with SQL server authentication. Is it possible to access the SQL Server password policy and expiration through the .NET 3.5 framework? I would like add the following functionality to my login form:
Ensure passwords meet policy standard.
Prompt a user to change their password when it is due to expire in 5 days or less.
Thanks in advance.

I have a 3 node cluster running windows 2003 x64 sp1 and SQL Server 2005 version 9.00.2153. My problem is the following...
This Saturday I migrated a web application's database to this server. After restoring the database I created the sql login for the service account, set the password and disabled the password policy for this login. I then ran sp_change_users_login to attach the already existing db user with the same name to the login. I changed the connection string for the application, tested the application connectivity and functionality then detatched the old database on the old server. Everything went like clockwork, no problems at all.
Come Monday morning at 8:35 I started getting alerts that the web site was down. I tested the site and sure enough it was down. I then attempted to connect to the database server using the login that was created for the app and the connection failed. I logged in with my ID and got in fine. Nothing showing to be wrong with the DB, I checked the new login and somehow the "Enable Password Policy" had been set for the new login. I disabled it and still no connection. I went to the database and checked the DB user and somehow the link between it and the login no longer existed. I reran the sp_change_users_login and restested the web site and verified that that web site was back online.
My question is this, is there any stored proc that resets these values back to default for some reason, a series of events that might revert the "Enable Password Policiy" to the default for a login, or is there a particular domain level operation that might occur such as Security Polcies that would affect these settings in SQL?
No one else was on the machine when I went to check it out at 8:40 so it has left me puzzled.
Any help would be appreciated.
Thanks.

I am trying to create a login using my application.
The application creates the user and password itself .
when working with sql server 2000 it works fine.
when i try to install my application with sql server 2005 it is displaying the error .
'Password does not meet windows policy requirements
because it is not complex enough'
I want to keep the same password.
Is there any way to disable/uncheck this option by default?

I am receiving the following error message when attempting to create a new SQL Authenticated login id.
Password validation failed. The password does not meet the requirements of the password filter DLL. (Microsoft SQL Server, Error: 15119)
I have four servers all running SQL Server 2005 SP2 on Windows 2003 Ent. SP1. Of the four servers, only one received the above error message using the same TSQL below.
CREATE LOGIN TEST_LOGIN WITH PASSWORD = 'pvif9dal' MUST_CHANGE, CHECK_EXPIRATION = ON
All four servers are in the same domain, which if I understand correctly, the password policies are therefore inherited at the OS level by the domain. The password being used is within the password policies of the domain.
Any ideas as to a root cause?

Hi all,We recently started to receive complaints about our install project notworking and giving and shitload of error messages related to SQL. Welater found out that the problem was the users we were trying to bindto we're not created because of the domain password policy featureimplemented into SQL Server 2005.After much dabbling around the SQL scripts that created the databasestructure, we came to the conclusion that only this piece of code couldcorrect our problem :CREATE LOGIN mynewuser WITH PASSWORD = '', CHECK_POLICY = OFF,CHECK_EXPIRATION = OFFThis runs perfectly fine on SQL2005, but not on SQL2000. We have beensearching for a way to have code in SQL files executed on install thatdoesn't fail to compile when run against the server and that willbypass the password policy in case it's a SQL Server 2005...Right now we are testing a feature available in MSI that can filterscripts not matching a database version, but the problem with this, isthat we are missing a lot of features that InstallShield has. In short,we need Help to fix this issue and be able to continue withdevelopment.In hopes to receive a a prompt anwser

We run a few shared hosting servers in the UK, now we used to run mssql 2000 and moved to 2005 in december 2005.
Microsoft SQL 2005 9.00.1399.06
Microsoft SQL Server Management Studio 9.00.1399.00
Microsoft Analysis Services Client Tools 2005.090.1399.00
Microsoft Data Access Components (MDAC) 2000.086.1830.00 (srv03_sp1_rtm.050324-1447)
Microsoft MSXML 2.6 3.0 6.0
Microsoft Internet Explorer 6.0.3790.1830
Microsoft .NET Framework 2.0.50727.42
Operating System 5.2.3790
We were in the process of improving security on some of our new servers, in the windows password policies settings we enabled the following
minimum password length = 6 characters
Password must meet complexity requirments = enabled
sql 2005 authentification was set in mixed mode, but we have tried windows authentification only as well.
Now when you try and add a new user even if the password meets all requirments you get an error password is to short etc, we used sql managment studio both manually creating a user and scripting with sql, both with the same result.
In the shared hosting environment we need passwords to be secure, the only way we can get sql users to be created is to disable windows password policies which causes security problems.
We would prefer to use sql authentification not windows but even when we use sql authent it still seems to use the windows password policy and the same error occurs
has anyone else found this problem?
could do with a fix asap!

Hi!
I am installing SQL Server 2005 Express as part of my setup. On Windows 2003 Servers with password policy enabled, the SQL Server 2005 Express installation fails. Here is the error I am getting - "the sa password must meet SQL Server password policy requirements. For strong password guidelines, see Authentication Mode, in SQL Server Books Online.". If I disable the password policy, the SQL Server 2005 Express installation is OK.
Is there a parameter that I can pass to the command line to get around this?
Thanks!

What are the exact requirements implied by the sql 2005 option:
"Password Must Meet Complexity Requirements "
TIA,
Barkingdog
P.S. I found this one:
-Cannot contain all or part of the username
-Must be at least 6 characters long
-Contain 3 of the 4 following character groups
- A to Z
- a to z
- 0 to 9
- Special Characters i.e. ! ^ $ *
and I have also found
"At least 7 characters in length"
Combines letters. numbners, and symbolds
Is not a dicitonary word, name of a command, person's name or user's account name
As the saying goes "close, but no cigar!"

I've legacy code that requires a blank password for a SQL Server login.
This works fine on 2000 or 7.
How can you allow blank passwords on SQL Server 2005 without changing the windows policy?
Is there a stored procedure to do this?
I know you can now use CREATE LOGIN and set CHECK_POLICY to no on SQL 2005 when creating logins, but this needs to run on SQL Server 7/2000 and so its using sp_addlogin.
(NB: I can't easily change the legacy code to work conditionally on SQL Server 2005)

I have modified the Security Settings>Account Policies>Password Policy on my PC as follows:
Minimum password length: 10 characters
Password must meet complexity requirements: Enabled
However, when creating a login within SQL Server 2005, which does not adhere to the amended policy, this does not seem to be taken into account:
CREATE LOGIN testlogin WITH PASSWORD='a',
DEFAULT_DATABASE=[master],
DEFAULT_LANGUAGE=[us_english],
CHECK_EXPIRATION=ON, CHECK_POLICY=ON
have tried restarting the SQL Server and rebooting the PC, but this does not solve the problem.

Numerous articles (e.g., http://www.microsoft.com/sql/techinfo/administration/2000/security/securingsqlserver.asp, even one that I wrote, http://www.dbazine.com/sql/sql-articles/cook12) state that to secure SQL Server, the SQL Server services should not run as Local System. That advice is useful only if making the change is not overly disruptive or is even allowable. My two most recent clients have absolutely rigid password expiration policies that require all account passwords to be changed at regular intervals. Realistically, that makes a compelling case for running as Local System.

We need to use SQL Server Authentication for some reason and would like to enforce Password Policy with 90-day expiration period. I found "Change password" dialogue appears when I first logged in with the new user, but don't know
(1)what happens when the user failed to change the password before it's expired or
(2)how a user can change his password in advance of the expiration date with no particular server-level permission.

I have a complicated question that involves the password policy defined within Windows Server 2003 and how it is used in Microsoft SQL Server 2005. I recently installed windows server 2003 on my development system. I am a person that prefers to develop in the same OS that our application runs in production. After installing 2003, then a Domain administrator added my machine to our corporate domain. Now, I cannot change the local password policy to allow a simple password. I believe this is due to policy inheriting from the domain that the machine belongs to.
This ties back into SQL Server 2005 because installing sql server on a Server 2003 causes SQL Server 2005 to follow the password policies defined at the OS level. This breaks our application in a subtle way in that we create login accounts for new client databases with random password. Because the password is random it sometimes conforms to the policy and sometimes not.
In production environments, the password policies are configured differently. So I need to one of the following options:
-change the group policy/inherited policy on my machine to not inherity from the domain I joined (prefered solution but don't know HOW)
-change SQL Server to not use OS password policy
-change code to use CREATE LOGIN statement with CHECK_POLICY=OFF or change password generation code to use a stronger password. (don't want to do this as the code change is only accomodating non-production environments)
If someone has a better place to post this question, I would sure appreciate it.

Hello Everyody,
Some background: I have a SQL server 2000 server that I just restored from backup after complete OS reinstallation. I have retored all databases (except the master) and I still have the mdf and ldf file from before reinstallation (master.mdf as well).
Now my problem is that I have 1 application that use a specific SQL user with a password that the application choose itself and of course this application doesn't work anymore because I didn't restore the sql users (I use windows authentification as much as possible). I cannot do anything to the application to use another password but I know the login used.
My questions is "How to I recover the password?". Is there a way to log the password that this application send to sql or from the old master.mdf file?
Any help would be greatly appreciated.
Bruno.

Hello,
in SQL Server 2005 I have an application role that is being used to limit access to my server data from third party applications. Everything is working well, except changing the Application role password.
I set up a small form that allows an administrator to change the App Role password through the front end app. I cannot, however, seem to get the Password field in my approle to accept a parameter.
For example:
declare @newpassword varchar(128)
set @newpassword = 'foo'
ALTER APPLICATION ROLE MyApplicationRole
with PASSWORD = @newpassword
This procedure gives me a syntax error in the last line. It will accept a string in quotes but not a varchar parameter.
Ideas?

I have recently restored an SQL Server 2000 database on SQL Server 2005
A number of constraints on the database had previously been disabled
A monthly process that is carried out, imports data into 'Table A'.
This process now crashed, being unable to truncate table as it referenced by 'Table B'
Although when i check the properties of the constraint the 'enforce foreign key constraints' is set to no.
Is there a known issue with restoring databases on 2005,
Any help greatly appreciated.

I've got a table that includes:CREATE TABLE [dbo].[Content] ( [Id] int IDENTITY(1, 1) NOT NULL, [ParentId] int NULL,
I'm wanting to make sure that a ParentId must be in the table as Id someplace else. When I try to do it by making it a foreign key get the error:
--------------- SQL ---------------
ALTER TABLE [dbo].[Content]ADD CONSTRAINT [Content_fk3] FOREIGN KEY ([Id]) REFERENCES [dbo].[Content] ([ParentId]) ON UPDATE NO ACTION ON DELETE NO ACTIONGO
---------- ERROR MESSAGE ----------
There are no primary or candidate keys in the referenced table 'dbo.Content' that match the referencing column list in the foreign key 'Content_fk3'.Could not create constraint. See previous errors.

Hi I have a problem. I have a replicated database. Now I have a couple of tables within the database where I delete the content row by row and caluted the new record and insert them. Now when I do this on the development system that is unreplicate it is fine. However on production that is replicated I get this error:
System.Web.HttpUnhandledException: Exception of type System.Web.HttpUnhandledException was thrown. ---> System.Data.SqlClient.SqlException: INSERT statement conflicted with COLUMN FOREIGN KEY constraint 'FK_VARLISTS_USERVARLISTS'. The conflict occurred in database 'BHP', table 'USERVARLISTS', column 'AutoID'.
INSERT statement conflicted with COLUMN FOREIGN KEY constraint 'FK_VARLISTS_USERVARLISTS'. The conflict occurred in database 'BHP', table 'USERVARLISTS', column 'AutoID'.
INSERT statement conflicted with COLUMN FOREIGN KEY constraint 'FK_VARLISTS_USERVARLISTS'. The conflict occurred in database 'BHP', table 'USERVARLISTS', column 'AutoID'.
Now I persume this is caused by the foreign key being contrained by the replicated database. I had though about unticking the box 'Enforce Relationship for replication' but I am not sure what problems this may cause.
Woudl this fix my problem? If not do you have any idea what would.
Thanks Ed

Hi,I have two tables Table A and B, below with some dummy data...Table A (contains specific unique settings that can be requested)Id, SettingName1, weight2, lengthTable B (contains the setting values, here 3 values relate to weightand 1 to length)Id, Brand, SettingValue1, A, 1001, B, 2001, null, 3002, null, 5.3(There is also a list of Brands available in another table). No primarykeys / referential integrity has been setup yet.Basically depending upon the Brand requested a different setting valuewill be present. If a particular brand is not present (signified by anull in the Brand column in table B), then a default value will beused.Therefore if I request the weight and pass through a Brand of A, I willget 100If I request the weight but do not pass through a brand (i.e. null) Iwill get 300.My question is, what kind of integrity can I apply to avoid the userspecifying duplicate Ids and Brands in table B. I cannot apply acomposite key on these two fields as a null is present. Table B willprobably contain about 50 rows and probably 10 of them will be brandspecific. The reason its done like this is in the calling client code Iwant to call some function e.g.getsetting(weight) .... result = 300Or if it is brand specificgetsetting(weight,A) ..... result = 100Any advice on integrity or table restructuring would be greatlyappreciated. Its sql 2000 sp3.Thanksbrad

I wish to use the same data to update 2 different tables.
There is no green arrow output from the OLE DB data destination, so I can't have another component following on from the first insert.
This means I have to use the Multicast to 'copy' the data prior to the first table insert.
I can then use the data to perform inserts to both tables.
However, there is an FK constraint between these two tables, so I need to wait until the first table insert has finished before performing the second table insert.
How can I do this? How can I make the second insert dependent on the first?

I am having a pretty major problem with my SQL server. Everytime that I try to query the database I receive a timeout expired error. Even trying to open the query anylyzer, it presents me with that error. We have a we based ISP management solution and it cannot access the SQL either. This was an all the sudden problem and I have ran the performance monitor to try and look at the statistics. Everything seems like it is checking out. I even tried increasing the Timeout up to 20 seconds and it still will not function properly. Any suggestions?
