| Parameter : login/password_downwards_compatibility |
------------------------------------------------------------------------
------------------------------------------------------------------------
| Short Description : Backward compatibility of passwords |
------------------------------------------------------------------------
------------------------------------------------------------------------
| Parameter Description : |
| ----------------------- |
| |
| As of Basis release (SAP_BASIS) 7.0, the system supports logon with |
| passwords that can consist of up to 40 characters (previously: 8), |
| and for which the system differentiates between upper- and |
| lower-case (previously: system automatically converted to |
| upper-case). All Unicode characters are also supported. |
| |
| Unfortunately, this change is not backward compatible. |
| The passwords are stored as backward incompatible hash values. If |
| this system is operated with other systems, which only support |
| backward compatible password hash values, the system must react |
| appropriately. |
| |
| The values of this profile parameter define the desired behavior |
| (Default value = 1): |
| |
| 0 : No backward compatibility; system generates only new |
| (backward incompatible) password hash values. |
| 1 : System also generates backward compatible password hash |
| values internally, but does not evaluate these for logons |
| (to this system) using a password; this setting is required |
| if this system is the central system of a Central User |
| Administration and systems that only support backward |
| compatible password hash values are also connected to the |
| system group. |
| 2: The system also generates backward compatible password hash |
| values internally and evaluates these if a logon using a |
| backward incompatible password failed, to check whether logon |
| with the backward compatible password (truncated after eight |
| characters and converted to upper-case) would have been |
| accepted. This is logged in the system log; the logon |
| fails. |
| (Identification of backward incompatibility problems). |
| 3 : As with 2; however, 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 password hash values. |
