How to process login with spring security core and grails -

i have integrated spring security core in grails project , s2-quickstart too.

so got basic gsps, domain controllers also.

so have 1 user id = 'me' , password (encoded) = 'password' inside database role = 'role_admin'.

now confuse api classes have. need show login page on start of project , if user enters correct id password should redirect dashboard page. have written following piece of code :

urlmapping.groovy ================= "/"(controller:"login", action:"auth")  logincontroller.groovy ====================== class logincontroller { def authenticationtrustresolver def springsecurityservice  def index = {        redirect(action: 'auth', params: params) } def auth = {        //checking licensing stuff        ....        ....  } def signin = {         if ( params.username == null )             redirect(action: 'login')         def config = springsecurityutils.securityconfig         if (springsecurityservice.isloggedin()) {             def targeturi = "/dashboard/loaddashboard"             redirect(uri: targeturi)     }         else         {              println params.username              println params.password               //don't know class should use here         } }  auth.gsp inside (login directory) ================================= <form action='login/signin' method='post' id='loginform' class='cssform' autocomplete='off'> <label for='username'>login id</label>                     <input type='text' class='text_' name='j_username' id='username' /> <label for='password'>password</label>                     <input type='password' class='text_' name='j_password' id='password' /> <input type='submit' value='login' /> 

so don't know how should pass username , password class inside else part of signin method of logincontroller.

any highly appreciated...

spring-security you.

just route users dashboard

    urlmapping.groovy ================= "/"(controller:"dashboard", action:"indexorwhatever") 

and annotate @secured annotation dashboardcontroller
