login/password_downwards_compatibility SAP Parameter attribute - password downwards compatibility (8 / 40 characters, case-sensitivity)








login/password_downwards_compatibility is a SAP Parameter attribute which is used to control password downwards compatibility (8 / 40 characters, case-sensitivity) information. This is available within R/3 SAP systems depending on the version and release level.

Below is the standard documentation available and a few details of the attributes values .

Parameter documentation


As of SAP NetWeaver (SAP_BASIS) 7.0, the system supports logon with passwords that can consist of up to 40 characters (previously: 8), and which are case-sensitive (previously, the system automatically converted from lowercase to uppercase letters). It is also possible to use any Unicode characters. Unfortunately, this change is not backward compatible. The passwords are stored as hash values that are not backward compatible. If you are using this system together with other systems that only support backward compatible password hash values, you need to react appropriately. The values of this profile parameter specify the desired behavior (default value = 1):
0 : No backward compatibility; the system only generates new password hash values (which are not backward compatible). 1 : The system also generates backward compatible password hash values internally, but does not evaluate these for logons (to the local system) with passwords; this setting is necessary if this system is used as a central system of a Central User Administration, and systems that only support backward compatible password hash values are connected to the system group. 2: The system also generates backward compatible password hash values internally and evaluates these if a logon with a password that is not backward compatible fails, to check whether the logon with the backward compatible password (truncated after 8 characters and converted to uppercase letters) would have been accepted. This is logged in the system log; the logon fails. (This setting identifies backward incompatibility problems.) 3 : As with 2, but the logon is regarded as successful (avoidance of backward incompatibility problems). 4 : As with 3, but no system log entry is written. 5 : System only issues backward compatible passwords hash values.
