Thanks Dominik and Alec for your inputs. Now I implement the authentication adapter using browser cookies with customized form and it works.
But I'm having another trouble. We use ldap authentication to store the user information. How could that work with cookies to do login and logout? ls there any example or reference materials available? I am pretty new in this area, any information will be very much helpful.

'Session Credentials'-plugin. (The basic HTTPBasicAuthCredentialsPlugin
does not provide logout mechansim.).
Don't forget to register the following adapter within your overrides.zcml:
