Problems using "IUserMappingService" - cannot access password

Hello

I´m trying to establish a connection between an EP 6 portal and a webservice.

I´m using the "UserMappingService" to store UserId and Password of the webservice.

I can access the UserID, but when I try to access the Password the appropriate function only returns "******" instead of the plain password.

this is the code I´m using:

IUserMappingService umap = (IUserMappingService) PortalRuntime.getRuntimeResources().getService(IUserMappingService.KEY);

IUserMappingData umData = umap.getMappingData ("mySystem", request.getUser());

HashMap umInfoOfUser = new HashMap ();

try {

umData.enrich (umInfoOfUser);

} catch (NoLogonDataAvailableException e) {

e.printStackTrace();

}

String mappedUser = (String) umInfoOfUser.get ("user");

String mappedPassword (String) umInfoOfUser.get ("mappedpassword");

mappedPassword returns "*****"

Can anyone tell me how to get the real password ?
