Invalid username/password for sop user

 Hi,

I am able to login into Business Modeller from the local machine as sop user.

But from the Collborator Workbench when I login as sop user, it gives Invalid username/password

I tried changing the password for sop user from Business Modeler through SOP credentials> Security Tab> Create/Modify User>

Before changing, the credential was  sop/sop

I changed the credential to sop/sales.

Then I restarted the Application Server.

Still I get the same error when I login with new password for sop.
