Apache Roller 4.0 login

[kranthi chamarthi]

Hi,
I am trying roller for blogs in my site. I am developing my site in Flex2+java and i am having a link in the site clicking on which will take the user to the roller login page. Now my problem is i want the user to directly login into his blog using the same credentials which the user uses to login into my site(I dont want separate credentials for roller and my site). I dont want roller to be as a separate entity.It should be as an integral part of my site as far as the login is concerned. Is this possible??? If it is possible then what are the changes that i need to do??? Please advise me.
Thanks

How are users logging into your site? I'm going to assume that the Apache library has a login method in it's API, in theory all you have to to is store the credentials when the user logs into your site and pass them to that API call..
