I got an error while creating a User for Domain Account. Below is the screen shot of the error (error : 15401)
Database instance is on SQL 2003 SP3. ( I know it is out of support, But the customer is relutanct to upgrade)
On Google search, i found below article which is best matching for this error
I have follows each step of troubleshooting. But still the issue persists.
Step 1. The login does not exist == The login is very much exist in the domain as i am able to add the same domain id to other database instances
Step 2. Duplicate security identifiers == i have used this query to find duplicate SID
/* SELECT name FROM syslogins WHERE sid = SUSER_SID ('YourDomain\YourLogin') */
But there was only one row returned with create date of today's.
Error while Assigning database level role (db_datareader) to SQL login (Domain Account)
Step 3. Authentication failure == Domain is available. User is able to login on other servers via RDP connection.
Step 4. Case sensitivity == Database collation is set to Case insensitivity. (CI)
Other two 5. Local Accounts & 6. Name resolution == is not applicable to me.
I tried other ways also.
A. Creating login and providing permission in one go only = User account is not created
B. Instead of GUI, use query to create login and provide required permission = Same error.
Does anybody has faced any such situation.
