Windows Authentication: User Name && Password Area Grayed Out And Unusable...
Aug 2, 2007
I'm trying to connect to a SQL Server 2005 database engine on a local network server. When I am presented with the Connect to Server dialog box, if I select Windows Authentication from the Authentication drop-down, the User name & Password area is grayed out and unusable. The domain user account I'm authenticated with is visible, but grayed out, and the password field is blank and unusable. I'd like to be able to connect as described in help:
User name
Enter the user name to connect with. This option is only available if you have selected to connect using Windows Authentication.
I can connect with either SQL Server or Windows authentication... but with Windows Authentication I'd love to be able to type a specific user name to select with :-)

This morning I attempted to connect to my local copy of SQL Server (2012) (Win 7) using Windows Authentication. I was unable to do so and per the error log it was due to error 18456 (invalid credentials).
Yesterday I changed my windows password. Is it possible for this to be the cause?
FYI, following is from the error logs:
2015-04-27 10:10:32.98 Backup BACKUP DATABASE successfully processed 0 pages in 0.451 seconds (0.000 MB/sec).2015-04-28 00:00:41.90 spid18s This instance of SQL Server has been using a process ID of 2096 since 4/21/2015 9:08:05 AM (local) 4/21/2015 1:08:05 PM (UTC).

This is an informational message only. No user action is required.
The logs showed the error occurred yesterday (4/28) which is about when I changed my password. The 17:09 log (last one) is when I shut down my computer. Note that I was logged into SQL Server when I changed my Windows password and worked with it several times through out the day.
Also, per the configuration manager SQL Server (MSSQLSERVER) (and all other services) is stopped and I was unable to start it ("The request failed or the service did not respond in a timely fashion).

We are looking at developing an SQL Server 2005 Database and I would like to use Windows Authentication rather than SQL Server Authentication to connect our client app.
In our development environment, we have two Servers, one being used as a file server and the other as an SQL Server. We have now set up a domain using the file server as the domain controller. (We had previously been set up to use a workgroup).
I have set up an active directory group called SqlDevelopers and added an active directory user called Jonathan to it.
On the SQL Sever, in management studio, I have set up a new server login which uses windows authentication called DomainSqlDevelopers. I used the GUI to verify I could see the domain and the group.
The default database is set to a test database on the server. A user in the test database is mapped to the DomainSqlDevelopers and given the Roles dbo, db_datareader, db_datawriter.
To test the log in, on the server, I logged out as administrator and in as Jonathan. I could successfully access the server through management studio using windows authentication.
However, if I log in as Jonathan on my client PC and try to access the SQL Server using management studio and windows authentication, I have problems.
The first time I try I will get a timeout error. If I try again will get either:
Login failed for user ''. The user is not associated with a trusted SQL Server connection
Or
Cannot generate SSPI context
I can€™t determine any pattern to which of the above errors I get.
However, if I log in as administrator on my client PC, I can connect to the server using management studio and windows authentication.
Sounds like Active Directory/Domain or other Network issue (Not really my area). I would be grateful for any help.
Thanks,
Jon

I'm almost sure that it's not possible, but I wanted to ask in case that I'm missing something.Is it possible to get the Windows user when someone logins using SQL Server Authentication? I know how to get the hostname, but I can't find how to make the next step.By the way, do sleeping connections affect performance? Would they consume resources such as RAM or network?

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 website written in asp.net and the current DATABASE logins do not use windows authenticaton. They are for online use only with a username and password. I'm trying to run my program locally on my machine and access the database locally. This is very frustrating. I'm able to connect to my database, but I can't login to it. Here's my connection string from ym webconfig file:
<add name="sqlConnectionString" providerName="System.Data.SqlClient" connectionString="Connect Timeout=8; Initial Catalog=linkexchanger; Data Source=SCOTSQLEXPRESS; "/>
I have the MSSQL engine running and I have connected with the SERVER. My database is in my directory tree of Microsoft SQL Management Studio Express. The server is SCOTSQLEXPRESSI have attempted to add a login to my sql database by right clicking on the security folder to create a new login. My understanding is that under windows, I don't need a uid and pwd in my connection string . Thus I tried removing all of this just as you see above, and I get an error message every single time I try to create a login with windows authentication.
Can someone please explain how I make this work?
Thank you.
Scot

Is there a way to connect to database using Windows authentication as a different user than what you've logged in with to your desktop?
For example:
I log on to my desktop as mydomainme. I'm developing queries using Management Studio against a database (on another server) where mydomainme doesn't have access, but the admins have granted access to mydomainJobs1. I have the password for mydomainJobs1, and I'm hoping I can connect to the database using that account without having to log-off my local desktop as mydomainme and then re-login using mydomainJobs1.
The analogy in the file/share-permissions world would be using "net use" from a command prompt:
net use \SomeServer /User:mydomainJobs1 jobs1password
Anything similar for SSMS?

I'm working on an ASP.NET project, and we're attempting to switch from SQL Server authentication to Windows authentication to connect to the database.
It works fine locally when I debug in Visual Studio, but when it hits the web server, I get the error: "Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection."
IIS has anonymous access disabled, and Integrated Windows Authentication is checked. The web.config file has:
<authentication mode="Windows"/><identity impersonate="true"/>
The database I'm attempting to access is on a different machine than IIS, and the connection string doesn't contain a username or password, and has "Trusted_Connection=Yes", and "Integrated Security=SSPI".
From what I've been able to find online, I'm guessing the problem is due to IIS and SQL Server residing on different machines, but I'm not sure how to fix it.
Any ideas?

Hi--
I am building an intRAnet website using windows authentication for website access and SQL Server access ( Trusted_Connection = true ).
In IIS I have these settings:
Allow Anonymous = unchecked (false)
Windows Authentication = Checked (true)
Digest windows = checked (true)
In my Web.Config file:
authentication="windows"
impersonate="true"
allowusers="*"
When I pull up the page these are my credentials:
Security.Principal.Windows: mydomainmyuserid (this is correct what it shows on my page)
Me.User.Identity: mydomainmyuserid (this is correct what it shows on my page)
Threading.currentThread.currentUser mydomainmyuserid (this is correct what it shows on my page)
So the ASP.NET page recognizes it is me and my domain. However, when i click a button to pull some data from a database I get the error message: Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.
My data access on SQL Server works fine. The weird thing is when I debug on my machine it pulls data fine. but when I copy the files to the windows 2003 server it doesn't work.
Do i have to do something with delegation?

Would be interested in any advice or comment on the issue we are experiencing with SQL 2005.
In order to test some DTS package migrations, we simply created a DTS package on SQL 2000 (using Export) to copy all database objects from one database to another.
Then we restored the source database on SQL 2005 server, migrated the DTS package, and tried to execute it.
The package migrated 'fine', ran part way, and then failed. Since then we have been unable to connect to the server (Database Engine, or Integration Services) using Windows Authentication. (Error 18456, Sev 16, State 11).
We can connect to the Database Engine using SQL Authentication (but not to Integration Services which only allows Windows Authentication).
We have been able to replicate this consistently - every annoying time we've tried it!
(Reinstalling SQL Server does 'fix' the issue ... until you try a similar package again).

Hello,
(Using win2k, sqlserver2k, framework 1.1)
I have an fairly data-heavy application that uses Windows authentication (Trusted connection/aspnet account) to connect to Sql Server. The site uses IIS basic authentication.
On the dev server everything works fine but when I move to the live server things get strange and it starts to crawl along. (Pages load OK but then it just crawls as it loads the datagrids etc. Sometimes it brings back incomplete/incorrect data )
BUT When I use Sql Authentication to connect to Sql Server and there is no problem at all!
Ok, there is something obviously wrong with the live server (which is identical setup to dev)but I dont know where to start.
Any ideas??

Hi all,
I've got two applications which both have a database on my MS SQL 2000 server. The problem is, one application must use Windows Integrated Authentication (which it is currently using and cannot be changed) whilst the other application which I'm trying to configure must use a SQL password.
Since the server has already been configured to use Windows Integrated Authentication for the existing database and application, how do I configure the other database to use the SQL password?
Thanks.

Hi all,
My work is using a shared application
which accesses a MSSQL 2000 database. To access the application, the
folder on the Windows 2003 Server is shared and users can access the
folder through a shared drive.
For the application to access the
database, it uses an ODBC connection to the MSSQL server which
originally used the SA password.
We have recently switched to using
Windows Integrated Authentication because we believe it offers a
higher level of security. However the only way in which we have been
able to enable this is to add the windows users to the SQL server.
The problem with this is that the
application sets permissions for individual users on what records
they can see within the database. We have found that by adding the
windows users to the SQL Server, they can bypass the permissions the
set by the application by simply using any application that can use
an ODBC connection, such as Enterprise Manager, and see all the
database.
One way around this would be to set up
domains of users with access privileges to the tables which reflect
the permissions set by the application, and configuring a view of the
data so they may only see the records that they have permissions to.
However to do this would require a high administrative cost to ensure
that changes made in the application are reflected in the privileges
of the SQL server.
Instead, is there a way the SQL server
can authenticate that the ODBC connection is coming from the correct
application using Windows Integrated Authentication?
This would allow the applcation to
determine security, and stop users from connecting to the SQL server
using other applications.
Alternatively, can the SQL server,
using Windows Integrated Authentication, also ask the application to
supply a username and password?
Any help with this matter would be
greatly appreciated.
Thanks!

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,
Say, I have configured my SQL to use Mixed Authentication. Now, I have a applicaiton which uses my SQL Server. The application just creates a database in SQL Server and uses the database to store its information.
This application also has a SYSTEM DSN under ODBC through which it accesses the database. For the application to access this database, should I only use SA (as my SQL instance is configured to use Mixed Authentication) or can I use Windows Authentcation too...
If I should only use SA, do we have a documentation which talks about this.
Thanks

Currently studying for 70-229.I'm trying to understand how security for users is managed in SQLServer. I've been using SQL Server for a few years now, but withoutinvestigating the bits that "just work".So, here's the scenario. This is more or less how I create all myapplications (which these days are all ASP.NET).I have a database called "TESTDB" (original, huh?)Now, I want to create a method for users to access this database, so Iopen EM, locate and expand the node for the server containing thedatabase, and open the "Security" node. Click on the "Logins" leaf,and in the pane right-click and select "New Login.."On the "General" tab I enter "TESTDBLOGIN" as the Name.Select "SQL Server Authentication", and put in a password.In the drop-down list of databases select "TESTDBLOGIN"Ignoring the "Server Roles" tab, I go to the "Database Access" tab andscroll down until I can see the "TESTDB" database. Check the "Permit"checkbox, and lo!, the "Database Roles for TESTDB" list is populated,with "public" already ticked. I check the "db_owner" box, and press"OK". It asks me to confirm the password, and once that's done there'sa new login called TESTDBLOGIN. What's more in "Users" leaf in the"TESTDB" database node there's a new user called "TESTDBLOGIN".All well and good. I can now create a connection using this login anddo more or less what I want in the TESTDB database.But.If I click the "Users" leaf in the "TESTDB" node, there are two users -"dbo" and "TESTDBLOGIN". If I right-click the "TESTDBLOGIN" user, Ican see that it has Database Role Memberships for the "public" and the"db_owner" roles. But if I examine the permissions on these two roles(by selecting the row, and then pressing the "Permissions" button) Ifind that there are permissions set for EITHER role - all the checkboxes are blank!So, how is it that I can do SELECT, UPDATE, INSERT and DELETEoperations via this login/user?Sorry it all took so long - I just wanted to get it right.ThanksEdward--The reading group's reading group:http://www.bookgroup.org.uk

Oracle and Teradata are able to capture the windows/client login that connects to their database with a functionnal ID.I've searched around and I don't think MS SQL can do this...I administer SQL 2014 server and also SAS Enterprise guide product. I've created sql server logins for several teams so everyone shares the same sql server login which is used to bind the SAS library to my SQL server database.
However, when looking at activity monitor, I can't drill down to which user is executing a particular query. I only see the SQL login which is share amongs 200 other folks.On the other hand, when they connect from SAS to Oracle or Teradata, I can see the shared login + additionally their windows NT login used to connect to SAS which is awesome....they can't fool me by using a shared/funcionnal ID....i still see who's using that ID...

Hi.
I wonder if it is possible to set forms authentication for report manager but leave report server "as it is". I need to authenticate users from external LDAP and can't use windows authentication for report manager, but I would also like to leave report server open for anonymous users. In that way authenticated administrators could create reports which anonymous users could read.
I tested the Security Extension Sample and got it working when I rewrote the authentication part with my own LDAP authentication.
If I have understood correctly, the report manager is just application inside report server so is it possible to use forms authentication with one application but still leave the report server with Windows authentication?

The problem is I dont know 'sa' password even. (I use windows authentication to connect to the server.) I need a proper uid and pwd for my .Net application access.

We are experiencing authentication/ Kerberos issues after a password for the MSA's has changed. We use MSA for our SQL 2012 and windows 2012 combination Servers. This errors creates issues while backing up and Service Broker connectivity.We had to restart sql services to fix it, but this not seem to be a resolution for me because the next time the password changes on these MSA's we may have to restart sql services.There seems to be a known issue for windows 2008 R2 servers and fix is available and we incorporated it. But the issue we are facing is on windows 2012 Server.

I am in the process of rolling out a sql server 2005 enterprise install and had a question regarding authentication. We will be providing sql hosting for a number of groups on our campus, many who are not using our campus-wide active directory, though they all have an AD account.
Windows authentication via the management studio appears to use your AD authentication tokens and will not allow them to enter a username/password combo. Is there any way to configure this?
I would like to use our campus AD for obvious reasons but if there is a requirement for passing tokens this isn't going to work right? It's also going to make database mirroring more of a challenge.
Thanks

My goal is to write a DR plan where i am restoring all user databases onto a diffrent server in a event of hardware failure. I was trying to figure out a way to extract DDL of user accounts and their permissions on all user databases so i can simplify my DR documentation.Â
Â
This is the plan I came up with...to restore all system and user dbs on a different Physical SQLServer.
1. build named instance $PROD
2. restore master database
   - startup sqlserver in single user mode -m or DAC sqlcmd -S ServerName -U sa -P<xxx> –A
   net stop MSSQLSERVER$PROD
   net start MSSQLSERVER$PROD -m
   - restore database master from disk e:master.bak with replace;
  Â
3. start sqlserver normally
4. stop SQLServer agent
5. restore msdb
-restore database msdb disk e:msdb.bak with replace;
6. restart SQLServer
7. Restore User Databases.
8. Run Sp_change_users_login for all users
-Sp_Change_users_logins 'auto_fix','username'
