How do I use Windows Authentication to connect to an Oracle database?
Currently, I just use an Oracle Username and password, however, a requirement is to give the user on install the option of selecting Windows Authentication since we offer the same as SQL.
You need to modify the AUTHENTICATION_SERVICES entry in SQLNET.ORA to this:
SQLNET.AUTHENTICATION_SERVICES= (NTS)
As well, you will need to setup the accounts in Oracle to match the Windows accounts. Have a look at http://www.dba-oracle.com/bk_sqlnet_authentication_services.htm for more details.

I have a database Connection established in odbcad and Microsoft Access (aswell as working in Excel) via ODBC and want to also get it working in Oracle SQL developer.
It is a Windows SQL Server as far as i know and I have tried several Settings, of which None works. I have also installed Driver for ODBC. I would like to Import Settings into SQL developer as applied in MS Access, is there any possibility?
No, SQL Developer is a Java application and uses a JDBC driver.
But if you look at the odbc properties for your connection, those should largely translate to what you need to define a basic connection.
Oracle:
Server name or IP address of the DB, port # for the listener, and the name of the SID or Service, plus a valid username and password is all you need to connect to Oracle.
What error do you get when you try to connect?
Show us what you're trying.
Update:
You're trying to connect to SQL Server but you're getting"
Native SSPI library not loaded
You're trying to use OS Authentication for your connection. For this to work with the jTDS driver, you need to copy a DLL file named ntlmauth.dll (which is for NT authentication) under the jtds-x.x.x-dist\x86\SSO\ or jtds-x.x.x-dist\x64\SSO\, to any directories in the PATH environment.
Please update your question such that's it's clear you're connecting to SQL Server and share the error message so others can find it.
I imagine this question is a duplicate of many previous iterations of the same challenge.
I have already installed sqldeveloper and i can launch SQLdeveloper client on my Linux Ubuntu 16.04 system.
The problem occurs during the first attempt of the new oracle connection from the client.
Error returned:
"I/O: The Network Adapter could not establish the connection"
I have already tryed several times to connect at the database but i still missing the username and password.
Is it possible to configure username and password for SYS/SYSTEM(or who else) user after installation?
Full stop.
You don't have a database.
Installing SQL Developer is just giving you a client you can use to work with an existing Oracle Database, which we often refer to as the 'server.'
SQL Developer is not a database.
So you need to get one.
Then you can use SQL Developer.
You have a few options. I talk about them in detail here.
SQL developer is just like the Key for Safe lock. And Database is the Safe.
So right now you have the key for Safe but doesn't have Safe.
Please get the safe first.
SQL Developer is not the Database. So Installing SQL developer will not give access to DB
Instead SQL Developer is the client side tool to retrieve the data or to do the modification on Database.
To get the database you need to download oracle DB from below link
http://www.oracle.com/technetwork/database/enterprise-edition/downloads/oracle12c-windows-3633015.html
We have a large SSIS solution with many connection managers pointing to Oracle. Provider is ODBC, data sources are set to defined system DSNs. So far we use user names and passwords and everything works fine. Now we want to switch to Kerberos authentication.
I can already successfully query the Oracle database using sqlplus with Windows authentication.
I'm having hard time achieving the same from SSIS using ODBC connection managers.
Is it possible to reconfigure the ODBC connection managers so they will use Windows authentication? How should be the connection manager configured?
The question is specifically about ODBC, please avoid answers like "use Attunity".
We use MS SQL Server 2016 Enterprise edition, Oracle 12.2.
I finally made it working, hope it helps someone.
I created a new DSN
as User ID I put [OracleUserName]
beware the square brackets! Those are necessary
the OracleUserName is user name configured on Oracle side (I do not know much about Oracle). The DBA configured the AD account to be able to login as this user.
I only have SQL Developer installed. What other programs do I need to install to create a local database. Please provide links.
SQL Developer is a client that access to a database server to extract data.
You need a database server.
If you operate with SQLDeveloper probably you like to install Oracle. There is a simplified version of Oracle that is called Oracle-XE. Search it over google and download the right version for your operating system.
Give the username and password of the user you created. You can specify localhost in Host name. If you haven't modified the port on which Oracle works then give 1521. If you haven't changed SID as well then give XE. You might be able to connect with DB.
I have set up an externally identified user for our Oracle 10g (10.2.0.3) database like this:
CREATE USER "OPS$DOMAIN\USER" IDENTIFIED EXTERNALLY;
Now I am trying to connect from a 10.2.0.1 sqlplus client using
connect /#TNS_NAME;
however I get
Invalid username/password.
[Edited]
Here is all the information I can currently give on this issue:
There are two virtualized Windows 2003 Servers, each running their own Oracle 10.2.0.3 database
There are two virtualized Windows XP Clients with the Oracle Client 10.2.0.1
All four machines are on the same virtual host and within the same domain
The same user is used to log in on both clients
Client 1 can use OS authentication to connect to Server 1
Client 1 cannot connect to Server 2 with OS authentication
Client 2 cannot connect to either database server with OS authentication
Both Clients can connect to either database server with schema owner/password
Four months ago, Client 2 could connect to Client 2 with OS authentication. I cannot tell if Client1->Server2 and Client2->Server1 worked, but I am almost certain it did.
Things I have considered:
I double checked the os_authent_prefix, which is "OPS$"
I tried recreating the user, and made sure everything was written in caps (we had problems in the past when we didn't have all caps)
I tried granting the create session privilege (someone suggested that somewhere; didn't help)
What could I be missing / What else could I try?
PS: Database security is not a concern here; I know OS Authentication is kind of insecure.
Since the problem is happening at the client can you please check the below parameter in sqlnet.ora file in the client machine
SQLNET.AUTHENTICATION_SERVICES= (NTS)
Even after that it does not work you can refer this article on os-authentication to check if any step is missing
