We use Dyn/Admin for many of the development related tasks of Oracle Commerce(ATG). However, the log-in ticket expires too frequently forcing us to enter credentials repeatedly. Some times we will also have to give both application server(weblogic/jboss) credentials and dynamo administration credentials. As we are not in a production critical environment where multiple people may access our DynAdmin and create issues, it is not necessary to have this security check every time we try to open DynAdmin of our development environment. I have found following solutions to be free of this issue. This can come in handy when we are doing active development and have to frequently access dynamo administration.
This approach works by enabling Lazy Athentication which means login will only be asked once per session. This means, as long as the session is not expired, dyn/admin will not ask for credentials again.
