Grails Spring Security: Switching between dual ROLEs -

in project users have dual roles, if such user logs in how can make him switch between 2 roles has can perform operations particular role provides.

appreciate step step process new grails. such literature online example highly appreciated.

update:- workridersuser loaduserbyusername(string username, string rolename) throws usernamenotfoundexception { // def conf = springsecurityutils.securityconfig //class user = grailsapplication.getdomainclass("person").clazz

    schemeuser.withtransaction { status ->          schemeuser user = schemeuser.findbyusername(username)          if (!user){ throw new usernamenotfoundexception('user not found', username)}          userprofile userprofile = userprofile.findbyemail(user.username)         representative representative = representative.findbyuser(user)         organization organization = organization.get(representative.organization.id)           def authorities = user.authorities.collect {new grantedauthorityimpl(it.authority)}          return new workridersuser(user.username, user.password, user.enabled,              !user.accountexpired, !user.passwordexpired, !user.accountlocked,              authorities ?: rolename, user.id, organization.companyname,userprofile)      }  } 

thanks

you need override loaduserbyusername method follows:

userdetails loaduserbyusername(string username, string selectedrole) {   // current selected role stored in member variable of userdetail class            this.selectedrole = selectedrole   return loaduserbyusername(username) } 

to show roles of current user within select box write own tag lib should like:

def authorities = springsecurityservice.principal.originalauthorities if (authorities.size() > 1) {     out << "<form name='switchroleform' action='switchrole' method='post'>"     out << "<select name='roles'>"     role tmprole     authorities.each {         tmprole = role.findbyauthority(it.authority)         // access current select role             if (springsecurityservice.principal.selectedrole== it.authority)             out << "<option selected value='${it.authority}'>${tmprole.name}</option>"         else             out << "<option value='${it.authority}'>${tmprole.name}</option>"     }     out << "</select>"     out << '<input class="switch" type="submit" value="switch"/></span>'     out << "</form>"         } 

i described switch logic in previous post.
