Not able to Login using BTEQ

I am not able to Login to Teradata 6.1/6.2 using BTEQ. I am able to login using Teradata 5.1
But I am able to login to Teradata 6.1/6.2 through Teradata SQL Assistant.
I included the following entry in the host file in the Windows folder

teradata teradatacop1

Then i made a file like .logon teradata/Username,Password;
Using BTEQWIN i given the command like .run file=path of the above file

I am getting the following error message
*** Error 3004 User identification is not authorized.
*** Error: Logon failed!
*** Total elapsed time was 3 seconds.
Teradata BTEQ 08.02.04.00 for WIN32. Enter your logon or BTEQ command:
*** Warning: EOF on INPUT stream.
Teradata BTEQ 08.02.04.00 for WIN32. Enter your logon or BTEQ command:

Can anyone help me out to login through BTEQ. Can any one clarify me why "User identification is not authorized" message appears while connecting using BTEQ where i was able to login using Teradata SQL Assistant.
Regards,

Manu.
