In SAP this hash value is stored in table USR02 and classified according to their code version. A unique hash value cannot be converted back to the original text. It is a unique strings of characters (consisting of special characters/ numbers/ alphabets) for a particular text generated via cryptographic function. Note that a hash itself isn’t an encryption. What these algorithms do is, during user creation new/reset of plain text passwords are converted to a unique signature for that particular text called hash. SAP uses a number of (depending upon kernel release) cryptographic algorithms to manage passwords. We will look for a common scenario in which the CUA central system is at a lower release 7.00 or 7.01 whereas the child systems are at a higher release >=7.02.įirst we will see a short introduction to hash algorithm. Now the error “Password hash is rejected password is deactivated” can be due to a number of situations depending on the SAP kernel release version and parameter login/password_donwards_compatibility (The parameter will be discussed later). In this blog I will illustrate an example on while using a CUA system in our landscape along with certain connected child systems, while changing a password for a user, how I came across & sorted the following error log “Password hash is rejected password is deactivated” and later secured the landscape via SAP newest hash procedure iSSHA-1.
