Laravel making connection with Sql Server with different computer user account

I am new to Laravel and working on Laravel 5.4 version. I am creating an small CRUD application. My database is on Sql Server.

Now, when I am doing new registration, Laravel throwing an error given below:

SQLSTATE[28000]: [Microsoft][ODBC Driver 11 for SQL Server][SQL Server]Login failed for user 'SYSDEV\ABC'  

while I am login in computer with an account 'SYSDEV\DEF'.

On My system (SYSDEV), I have two user accounts:
1. ABC
2. DEF

I have also checked all the needed Laravel configuration files and everything is fine. I don't know why the laravel trying to make connection with another user account? Is there can be another reason?

Please anyone tell me How can I fix this issue?
