To Reset Administrator Password through Config Tool

It may sometimes happen that a user enters the wrong password a number of times (by default, 3) and if that user is the administrator, then the administrator user is locked. This prevents all sorts of things happening. To unlock the administator, use the following process
You need to use the Config Tool and the process is:

1) Go to the Server Installed path i.e. usr\sap\\\J2EE\configtool\
2) Choose configtool.bat and start it.
3) Under Global Server Configuration, choose Services.
4) Find com.sap.security.core.ume.service, click it.
5) Under Global Properties, find ume.superadmin.activated
6) Set the Custom value to TRUE. Click on SET to apply the new value
7) Apart from that, you have to set another property i.e.
8) ume.superadmin.password, define some password.The password that you are defining is for SAP*. save the changes.
9) Restart the cluster / server. Issue the command stopsap to do so.
10) Log on to Portal with SAP* as user and the defined password.
11) Create a User with Super Administrator role.
12) Go back to Config Tool and set the Custom Value as default value i.e. FALSE. save the changes.
13) Restart the Server.

Incase if you deploy a Application i.e. a Webdynpro or PAR and the Admin Password is not configured properly or is locked then

1) Go to Config Tool.
2) Choose Secure Store, right click.
3) Choose Admin\Passowrd\Systemid\
