I am trying to host a SQL server database, but whenever I try to connect to it I get this error:
The login is from an untrusted domain and cannot be used with Windows
authentication
I am connecting through Matlab using the following command:
conn = database('Clinical_Data','DoyleLab07\Acc','','com.microsoft.sqlserver.jdbc.SQLServerDriver','jdbc:sqlserver://DOYLELAB07\SQLEXPRESS:54287;database=Clinical_Data;integratedSecurity=true;').
Connecting to the database using matlab worked fine as long as I was using matlab on the computer which I was using to host the server. However, when I use another computer and the same Matlab command I get the error I showed above.
When I look under control panel\system. I notice that no domain is listed on my host PC or the PC I am using to connect to the host, but both computers are in the same workgroup. Would I be able to fix my problem by creating a domain and adding the foreign PC and the host to that domain? If so, how can this be accomplished?
Any suggestions will be very much appreciated.
Thank you for reading my post.
Getting rid of Integrated Security=true worked for me.
In order to use Windows Authentication one of two things needs to be true:
You are executing from the same machine as the database server.
You have an Active Directory environment and the user the application is executing under (usually the logged in user) has rights to connect to that database.
If neither of those are true you have to do one of two things:
Establish a Windows Domain Controller, connect all of the relevant machines to that controller, then fix SQL server to use domain accounts; OR,
Change SQL server to use both Windows and SQL Server accounts.
By FAR the easiest way is to change SQL Server to use both Windows and SQL server accounts. Then you just need to create a sql server user on the DB server and change your connection string to do that.
Best case option 1 will take a full day of installation and configuration. Option 2 ought to take about 5 minutes.
If your SQL Server is on one domain controller and you are trying to connect to it from another domain controller then you will get this error when
IntegratedSecurity = true;
This will happen even if you include a valid SQL Server username and password in your connection string as they will automatically be over-written with your windows login and password. Integrated security means simply - use your windows credentials for login verification to SQL Server. So, if you are logged in to a different domain controller then it will fail. In the case where you are on two different domain controllers then you have no choice but to use
IntegratedSecurity = false;
Now, when Integrated security is false SQL Server will use the SQL Server login and password provided in your connection string. For this to work, the SQL Server instance has to have its authentication mode configured to mixed mode, being, SQL Server and Windows Authentication mode.
To verify or change this setting in SQL Server you can open the SQL Server Management Studio and right-click on your server name and then select Properties. On the pop-up that appears select Security and you will see where to alter this setting if you need to.
I've had this same issue when using DNS aliases and hosts files to connect to a machine using a different domain name.
Say you have a SQL server called sql1 on mydomain.com - which is an Active Directory domain - and you also have a DNS zone for mydomain.net, and - for consistency - you set up a DNS alias (CNAME) record for database.mydomain.net --> sql1.mydomain.com
You'll be able to connect to sql1.mydomain.com using Windows integrated security, but won't be able to connect to database.mydomain.net even though it's the same server because the domain name doesn't match your AD domain.
This error message can also occur if the account you are using to access the SQL server is locked out by the domain.
I was facing the issue while connecting to SQL Always On Listener. Disabling the loop back check resolved the issue.
Edit the registry using regedit. (Start –> Run > Regedit )
Navigate to: HKLM\System\CurrentControlSet\Control\LSA
Add a DWORD value called “DisableLoopbackCheck”
Set this value to 1
https://blog.sqlauthority.com/2017/04/18/sql-server-login-failed-login-untrusted-domain-cannot-used-windows-authentication/
Why not use a SQL Server account and pass both the user name and password?
Here is the reason why.
In short, it looks like you have an authentication issue.
The problem with workgroups is there is no common Access Control List like Active Directory (AD). If you are using ODBC or JDBC, the wrong credentials are passed.
Even if you create a local windows account (LWA) on the machine (SE) that has SQL Express installed (SE\LWA), the credentials that will be passed from your client machine (CM) will be CM\LWA.
As mentioned here, you might need to disable the loopback
Loopback check can be removed by adding a registry entry as follows:
Edit the registry using regedit. (Start –> Run > Regedit )
Navigate to: HKLM\System\CurrentControlSet\Control\LSA
Add a DWORD value called “DisableLoopbackCheck” Set this value to 1
If you using windows authentication make sure that password of the user hasn't expired. An expired password can explain this error. This was the problem in my case.
Same Error with Connection String in Visual Studio dev environment
Our development database server was recently given a self-signed certificate so it automatically became untrusted. This resulted in the login error cited above. I added TrustServerCertificate=True to my connection string and it works now.
"Server=TheServerAddress; Database=TheDataBase; User Id=TheUsername; Password=ThePassword; TrustServerCertificate=True"
NOTE: This certificate configuration is not recommended for production environments.
In my case the Aliases within SQL Native Client 11.0 Configuration were pointing to invalid server/IP. Once updated it worked correctly.
To check:
1. Start "SQL Server Configuration Manager"
2. Navigate to "SQL Native Client 11.0 Configuration" and then "Aliases"
3. Ensure "Alias Name" and "Server" match correctly for TCP/IP
Following worked for me to get access from another machine to SQL Server using Windows Authentication. This approach may be useful only in development/test environment. E.g. you need to update password manually once you change it on your working machine.
On machine with SQL Server go to Control Panel and add new Windows User with same username and password as is on your working machine. Then create SQL Server login for this user:
CREATE LOGIN [SQLSERVERHOST\myuser] FROM WINDOWS;
Now you can use this login for Windows Authentication.
If you receive error 'The login is from an untrusted domain', this may mean that you changed password on your working machine and now need to update password on SQL Server machine.
Just adding my suggestion for a resolution, I had a copy of a VM server for developing and testing, I created the database on that with 'sa' having ownership on the db.
I then restored the database onto the live VM server but I was getting the same error mentioned even though the data was still returning correctly. I looked up the 'sa' user mappings and could see it wasn't mapped to the database when I tried to apply the mapping I got a another error "Fix: Cannot use the special principal ‘sa’. Microsoft SQL Server, Error: 15405". so I ran this instead
ALTER AUTHORIZATION ON DATABASE::dbname TO sa
I rechecked the user mappings and it was now assigned to my db and it fixed a lot of access issues for me.
Joining a WORKGROUP then rejoining the domain fixed this issue for me.
I got this error while using Virtual Box VM's. The issue started to happen when I moved the VM files to a new drive location or computer.
Hope this helps the VM folks.
We now use a privileged account management solution that changes our passwords regularly. I ended up receiving this error after my password was changed. Closing and re-opening SSMS with the new password resolved my issue.
I started to get this error when i tried to login to SSMS using 'windows Authentication'. This started to happen after i renamed the Windows SQL server. I tried everything to resolve this error and in my particular case changing the machine names in the 'hosts' file to reflect the name SQL server name change resolved the issue. C:\Windows\System32\Drivers\etc\hosts
I had this problem because we where using a DNS name from an old server, ponting to a new server. Using the newserver\inst1 address, worked. both newserver\inst1 and oldserver\inst1 pointed to the same IP.
Yet another thing to check:We had our nightly QA restore job stop working all of a sudden after another developer remoted into the QA server and tried to start the restore job during the middle of the day, which subsequently failed with the "untrusted domain" message. Somehow the server pointed to be the job's maintenance plan was (changed?) using the ip address, instead of the local machine's name. Upon replacing with the machine name the issue was resolved.
TLDR: Changing the DNS server to the loop back address worked for me.
I am working in VirtualBox and had setup two Windows Server 2016 instances. Server A is configure as a Domain Controller and Server B as an SQL Server. After adding Server B to the domain I cold not connect to with Management Studio from Server A. I was getting the "The login is from an untrusted domain and cannot be used with Windows authentication".
My initial configuration had the server getting its IP from the VirtualBox DHCP server.
I changed this to use static IP and entered the 127.0.0.1 address in the Primary DNS and this worked for me.
Hope this helps someone passing by.
I enabled Trust Server Certificate in the Connection Properties and it worked for me
You might find out that you have more than one connection string, and you forgot to change the other one to Integrated Security to false. It happened to me. This answer might help someone.
I was focusing on the web config and the access rights, after a long hustle i remembered that I have another connection string in one of my classes for the emails, I had to change the connection string on the class to use the web config one.
i removed Integrated Security=true and Trusted_Connection=True both of them , worked for me..
In .net Core also you may get this error if Trusted_Connection=True;
Is set. Sample setting in appsettings.json
ConnectionStrings": {
"DefaultConnection": "Server=serverName; Database=DbName; uid=userId; pwd=password; MultipleActiveResultSets=true"
},
Sometime SSMS hang and close all of sudden ,then you get below error when you reconnect to SSMS
i) The Login is From an Untrusted Domain and Cannot be Used with Windows Authentication
OR
ii) The target principal name is incorrect .Cannot generate SSPI context.
In both cases RESTART YOUR MACHINE.
I also had a similar error but then I realised I just had changed the password for my system which caused this error.
To resolve it , I simply logged out of the current session and logged in again and this time
Please Use This Connection URL It's Work Fine
"Data Source=Your IP Address;Initial Catalog = DatabaseName;User ID =sa;Password =your PassWord;TrustServerCertificate=True"
Example : "Data Source=192.168.150.122;Initial Catalog=StudentDb;User ID=sa; PassWord=123;TrustServerCertificate=True"
If you have two servers on the same domain (eg. APP and DB), you can also use Windows Authentication between the app and MSSQL by setting up local users on both machines that match (same username and password). If you don't have the passwords matched up, it can throw this error.
Following was working for me. hope this helps you
<add name="getconn" connectionString="Data Source=servername;Initial Catalog=DBName;Persist Security Info=True;User ID=sa;Password=***" />
I'm trying to create a data connection in DataZen to SQL Server 2014, but for any reasons it cannot connect.
My connection settings in SQL-Server:
I want to connect to the adventureworks database in DataZen:
But every time I get the following error:
I am really desperate right now and appreciate every tip. I tried with "secure connection" and without, also with username and without.
The admin-user in DataZen is called "admin". But I don't think, that this makes any difference?!
Thank you very much!
Put IP address of the server in Data Source
Put Database name in Initial Catalog
Then specify the username and password(for connecting to DB)
Test connection
I encountered a similar issue-- the resolution was to add a new SQL login (in SSMS) with SQL Server authentication. Make sure to give this user appropriate permission on the tables you'll be working with in DataZen. Once I did that I was able to use that new login to successfully test the connection.
I'm trying to create a database link from my Oracle AWS RDS instance to another Oracle database outside my VPC. I created the database link this:
create database link test
connect to myusername
identified by "mypassword"
using '(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=my.db.com)(PORT=1521))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=servicenameame)))';
However when I run a query against that database link I get the following:
SQL> select sysdate from dual#test;
select sysdate from dual#test
*
ERROR at line 1:
ORA-12545: Connect failed because target host or object does not exist
I did some googling of ORA-12545 and the majority of the issues people are having with this error is either an intermittent connectivity failure (of which mine is not, it fails every time), or a misspelled hostname/incorrect port. My issue is also not an incorrect hostname/port because I am able to CONNECT to my.db.com using the same connection string and query the database that way.
Does anyone have any suggestions?
Source Oracle database is:
Oracle Database 11g Release 11.2.0.4.0 - 64bit Production
Destination Oracle database I am trying to connect to is:
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
I (somewhat) found the answer I needed. The TLDR version is that after much googling and desk pounding I did an nslookup on the hostname of the database I am connecting to (the my.db.com portion of TNSNames). I modified the TNSNames to connect to the IPs returned by the nslookup. My final TNSNames looks something like the following:
(DESCRIPTION=
(ADDRESS_LIST= (LOAD_BALANCE=on)(FAILOVER=ON)
(ADDRESS=(PROTOCOL=tcp)(HOST=w.x.y.z1)(PORT=1521))
(ADDRESS=(PROTOCOL=tcp)(HOST=w.x.y.z2)(PORT=1521))
(ADDRESS=(PROTOCOL=tcp)(HOST=w.x.y.z3)(PORT=1521)))
(CONNECT_DATA=(SERVICE_NAME= servicenameame)))
The long version is that the Oracle host I am connecting to is configured with a Single Client Access Name (SCAN). After looking at the discussion on this post I went with just looking up the host name. I initially tried to modify the REMOTE_LISTENER in the AWS RDS Parameter Group, but that was not modifiable.

I'm trying to connect to oracle db on remote server through sql developer. I copied the connection details to tnsnames and I'm able to connect to the db.
However i have another db application which is same as sqldeveloper and when I try to make a connection, I keep getting this error. This application uses oracle jdbc thin client which requires hostname and SID.
I got the below error:
java.sql.SQLException: Listener refused the connection with the following error:
ORA-12505, TNS:listener does not currently know of SID given in connect descriptor
While troubleshooting, I changed the tns option in sqldeveloper and I have selected basic option to find out what went wrong and I realized that I'm able to connect to it because of the correct service name and not able to connect to the db via SID name even through sqldeveloper.
I have used some db queries to find out SID name but still i keep getting the same error. Please help me troubleshoot.
Thanks for your time..
ORA-12505 means your client passed a SID that the listener on the server end
didn't recognize at all.
In 10G and above You can use EZ connect without configuring the server side
like this:
sqlplus hr#liverpool:1521/DEMO
hr is the user name
liverpool is the server name
1521 is the port the listener for the DB is listening on
DEMO is the database SID
(OR)
If you still want to use tnsnames.ora, try running tnsping SID from your client.
On LINUX, You can also have ORACLE read a tnsnames.ora file from a local
path - just set TNS_ADMIN to the directory where your tnsnames.ora file is.
Otherwise, you need to configure tnsnames.ora in $ORACLE_HOME/network/admin
on the client
If you need to know the database SID, use this:
select sys_context('userenv','db_name') from dual;
See this URL:
Checking oracle sid and database name
I'm facing this problem too. Linux with oracle 11.2.0.1.
What I found was that the connection string must be:
sqlplus hr#liverpool:1521:DEMO
and not
sqlplus hr#liverpool:1521/DEMO
