SAPGuiUtil.Autologon method fails

Hello all.

I use this command in order to automatically logon to the local SAP installed on the machine.
The SAP version is 7.10.
SAPGuiUtil.AutoLogon SAP_ENV, "400", SAP_USER, SAP_PSWD, "EN"

This command worked fine when the user's password was 6 characters long.
Now, SAP policies have changed and an 8 character password is required.

This command now, fails to enter anything to the password field.
Cannot find anything that configures this.

Please assist anyone with an idea about this.

Thanks!!
