unable to login as platformAdmin

I am using JBoss EAP 6.4 and BonitaBPMCommunity-7.0.1-deploy on Java 8. I followed all steps to install and I am able to start server as shown below -
06:33:12,021 INFO [org.bonitasoft.engine.EngineInitializer] (ServerService Thread Pool – 58) Platform started successfully
06:33:12,021 INFO [org.bonitasoft.engine.EngineInitializer] (ServerService Thread Pool – 58) Initialization of Bonita Engine done! ( took 7236ms)

But when I use username “platformAdmin” with password “platform” I get following error :

Error:
06:48:02,814 SEVERE [org.bonitasoft.console.common.server.login.datastore.LoginDatastore] (http-/127.0.0.1:8081-1) Error while logging in the engine API.

I have the following lines Uncommented inside the JBoss root directory …

./bonita/engine-server/work/platform/bonita-platform-community.properties:
platformAdminUsername=platformAdmin

./bonita/engine-server/work/platform/bonita-platform-community.properties:
platformAdminPassword=platform

I have the following lines Commented inside the JBoss root directory …
./bonita/engine-server/conf/platform/bonita-platform-community-custom.properties:
:#platformAdminUsername=platformAdmin

./bonita/engine-server/conf/platform/bonita-platform-community-custom.properties:5:#platformAdminPassword=platform

Actually you need to login with the tenant administrator login and password: install/install (by default).

Platform administrator user is useful only when you run Subscription edition. Purpose of this user is actually to create new tenants (Community is limited to one tenant).

Thanks for the prompt clarification.
