Change the SAP standard authentication error messages text on sap portal logon page (including initial password change page) with custom /more generic messages as per client requirement.

authentication_022=Password missing
authentication_021=Authentication failed. Password locked
authentication_003=User account locked
authentication_002=User is not currently valid
authentication_000=User authentication failed

Solution

SAP error messages for logon page are stored in LogonMessages.properties file within sap.com~tc~je~security~impl.jar.

Ø Get sap.com~tc~je~security~impl.jar file from following server location.

usrsapj2eeclusterinservicessecuritylibprivate

Ø Take a backup of original jar before making modifications to it.

Ø Change the extension of jar from .jar to .zip. Unzip the content and navigate to

comsapengineservicessecurityexceptions

Ø If you want to change the English text, edit both LogonMessages_EN.properties and LogonMessages.properties file.Change Following key in both properties file as below

authentication_049=It is my custom message for – User authentication failed
authentication_026=It is my custom message for – Password change failed
authentication_025=It is my custom message for – New password and password confirmation are not identical
authentication_024=It is my custom message for – Password confirmation missing
authentication_023=It is my custom message for – New password missing
authentication_022=It is my custom message for – Password missing
authentication_021=It is my custom message for – Authentication failed. Password locked
authentication_003=It is my custom message for – User account locked
authentication_002=It is my custom message for – User is not currently valid
authentication_000=It is my custom message for – User authentication failed

Ø zip the content back with same name sap.com~tc~je~security~impl and change the extension to .jar .Make sure not to corrupt the jar.

Approach 1:

Ø Replace the original jar on server with this jar

Ø Restart your server

Approach 2:

You can package the modified jar into security.sda and deploy the modified security.sda directly through the admin tools. Deployment of sceurity.sda will cause the server to restart.

That’s it …You are done. Now your new changes will reflect.

Note:

This jar is part of security.sda which in turn is part of SERVERCORExx_x.sca. These changes will get overwritten by a patch/update of this sca .You need to repeat above steps to make your custom changes available again in the system.
