Displaying different login name while checking in file

Hi All,

I and my colleague is working on project, while i am trying to checking in a file I am unable to do it.

The detailed scenario is mentioned below:

Scenario 1 : (Myself) logged in, worked for some time and logged out.

Scenario 2 (Colleague) logged in, worked for some time and logged out.

Scenario 3 (Myself) logged in, checked out some files, one file checked out by me and one file checked out by my colleague in the same project folder. When my colleague is trying to check-in file checked out by my colleague's name it did not allow files to check-in in the vault it is displaying error as it was my login.

Can anyone help me on sorting out this issue!
