Leave new Amit Patil January 17, 2014 10:19 amThank You.. I have question here?As I tried this option, I am unable to access the User details further. I have 10 users & I am getting user group not individual user id's. Please help me.Reply Magne Rekdal January 17, 2014 12:32 pmPerhaps it was not a coincidence that these emails all came together.I have had an application run smoothly on 20+ sites for years, only to have this reported from two sites last week.The connection string was in both cases specified in an UDL file that the application refers to, and I used trusted login. The user's Windows account will (through an AD group) give access to both the file server and the database server. They should be able access neither, o

Here is our setup: We have four SQL servers that are in replication with each other. We add a new user to Windows Active Directory and add them to a group that is in SQL Server that we have been using for ages. The new user, when trying to authenticate using Windows authenication returns that error in the subject line. But, any users that were previously in Active directory work fine. At one point I had gotten sql server error SQL Server "caught up" becauuse we had a group of users that could not log in because of this error. I did some changes to the SPNs and ended up making it so no one could log in. Then I realized how the SPNs were supposed to look and fixed it. Then I guess some magic happened and those users were able to authenticate. I thought it was fixed, but it is obviously not as we had to add one new user and they cannot authenticate. What is interesting is that the user can authenticate with three out of the four SQL Servers. It is only this one server that is working incorrectly. I set up two SPNs for the SQl Service on this sql server. They look like - MSSQLSvc/[servername].[domain].local:1433 MSSQLSvc/[servername]:1433 These are actually registered to the Service account that we use for the SQL Servers. What is interesting is that I can't find the SPNs for the servers that are working anywhere. Any help would be appreciated! Edit: Also, another point to note is that if I try to add the user directly as a login into SQL server. I right click Logins and click Add Login then click search. I then type in [Domain]\[Username] and click check names. It validates the name as being correct. Then I click OK. And then OK again, and it gives the Error Windows NT user or group '[Domain]\[Usern
Server connection. July 1, 2009 Justin Stenning 6 Comments Login failed for user ‘username'. The user is not associated with a trusted SQL Server connection. This error occurs when you attempt to login to SQL Server using SQL Server Authentication mode (username + password) when the SQL Server instance is only configured for Windows Authentication. To fix the issue: Enable SQL Server Authentication Enable the "sa" user, and configure a password for it Restart the SQL Server Instance 1. Enabling SQL Server Authentication (or mixed authentication mode) a) Open SQL Server Management Studio b) Connect to the server using Windows Authentication c) Right click the "Server" node in the tree (the top level node), and select properties d) Select the Security page and select "SQL Server and Windows Authentication mode" as the "Server Authentication" value. SQL Server Security Properties 2. Enabling and setting the password for the ‘sa' login a) Run the following SQL statements against the master DB: ALTER LOGIN sa WITH PASSWORD = 'the password'
GO LOGIN sa ENABLE GO 123 ALTER LOGIN sa WITH PASSWORD = 'the password'
GOLOGIN sa ENABLEGO OR b) Expand the Security node in the SQL Server Management Studio and right click the "sa" user, and select "Properties", and then on the "General" page provide a password, and on the "Status" page select "Enabled". Change the login properties for 'sa' 3. Restart SQL Server Instance Right click on the server node in the SQL Server Management Studio again, and select "Restart". All the changes should now take effect. Like this post? Share it:TwitterGoogleFacebookMoreEmailLinkedInReddit SQL Server Post na
