8. authentication_003=User account locked

10. 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.

     \usr\sap\<sid>\<instid>\j2ee\cluster\bin\services\security\lib\private

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

     com\sap\engine\services\security\exceptions\

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

1. authentication_049=It is my custom message for – User authentication failed
2. authentication_026=It is my custom message for – Password change failed
3. authentication_025=It is my custom message for – New password and password confirmation are not identical
4. authentication_024=It is my custom message for – Password confirmation missing
5. authentication_023=It is my custom message for – New password missing
6. authentication_022=It is my custom message for – Password missing
7. authentication_021=It is my custom message for – Authentication failed. Password locked
8. authentication_003=It is my custom message for – User account locked
9. authentication_002=It is my custom message for – User is not currently valid
10. 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.
