The ADMIN/ADMIN login is the default for Tomcat (because we include that
user in the Tomcat's user configuration files). In WebSphere you would
need to log into the server with a user who is associated with the
JazzAdmins J2EE role.
Installation into WebSphere involves a little more work than the
document than you pointed to. Have you followed all of the steps from

@kesterto: DB connection is correct. No exception throwns
@lavinm: In fact, with both Tomcat and WAS, RTC Server can login with ADMIN/ADMIN as the default account to continue with setup wizard, that is steps to configure the RTC Server with db and talk with LDAP.
I follow correctly steps that uses to deploy jazz.was to WAS and it can run well but authorization.
I can not discover what is going on :((
