reduce password space on login screen from 40 to 8 in ECC 6.0

Hello

upgrade from R/3 4.6C to ECC 6.0 was performed.

Maximum Password length in R/3 4.6C is 8.

Maximum Password length in ECC 6.0 is 40.

Customer here wants Maximum Password Length in ECC 6.0 to be 8 and password rules to be applicable in ECC 6.0 same as in R/3 4.6C.

We have set the the following profile parameters

login/password_downwards_compatibility was to 5 .

login/password_charset was set to 0

After restarting SAP instance, maximum password length showed 8 when resetting the password using tx code su01.

However The space was not reduced on login Screen from 40 to 8 in ECC 6.0.

We want to reduce the space on login screen from 40 to 8 in ECC 6.0.

Please suggest the solution.

Thanks and Regards
