CAS 4 - Not able to retrieve the LDAP groups after

I have configured CAS 4 / Spring Security / Active Directory and able to authenticate successfully.

But I have difficulty in to retrieve roles and later use that for authorisation.

I have the roles available after the authentication in CAS but I want to pass this to the service (web app) so that it can be used to check the authorisation (for eg. hasRole('ROLE_EDITOR') )

I think I am making some configuration mistake in the below beans which I investigating further. I have shown these configuration fragments.

bean 'casAuthenticationProvider' and the property 'authenticationUserDetailsService'
bean 'ldapAuthenticationHandler' -- 'principalAttributeMap' property
bean 'attributeRepository'

After spending too much time to use the CAS feature to retrieve the roles and it did nt work... So I decided to retrieve the needed LDAP attributes myself after successful login. In my case I used Java, Spring framework, etc...

I have my class MyCasAuthenticationUserDetailsService that would looks like below and extends org.springframework.security.core.userdetails.AuthenticationUserDetailsService And in initialiseAdditionalUserDetails() method I retrieve the needed attributes and set in my own CasUser class which extends org.springframework.security.core.userdetails.User

        public class MyCasAuthenticationUserDetailsService implements AuthenticationUserDetailsService<Authentication> {

           @Override
            public UserDetails loadUserDetails(Authentication token) throws UsernameNotFoundException {
            sAMAccountName = token.getName();

            init();

            List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
            for (String role : getRoles()) {
                authorities.add(new SimpleGrantedAuthority(role));
            }

            CasUser user = new CasUser(sAMAccountName, NON_EXISTENT_PASSWORD_VALUE, authorities);

            // Sets additional user details
            user = initialiseAdditionalUserDetails(sAMAccountName, user);

            return user;
            }

              /**
             * Retrieves the user roles from LDAP
             * 
             * @return
             */
            private List<String> getRoles() {

            List<String> result = new ArrayList<String>();

            try {
                SearchResult searchResult = searchExecutor.search(connectionFactory, "(sAMAccountname=" + sAMAccountName + ")", "memberOf").getResult();
                LdapEntry entry = searchResult.getEntry();

                if (entry != null) {
                Collection<String> roles = entry.getAttribute().getStringValues();
                StringBuffer rolesCSV = new StringBuffer();

                for (String role : roles) {
                    int start = role.indexOf("=");
                    int end = role.indexOf(",");
                    rolesCSV.append(role.substring(start + 1, end));
                    rolesCSV.append(",");
                }
                String role = rolesCSV.deleteCharAt(rolesCSV.length() - 1).toString();
                String rolesArr[] = role.split(",");
                result = Arrays.asList(rolesArr);
                }

            } catch (LdapException e) {
                LOG.error(e);
            }

            return result;
            }


        /**
             * Initialise additional user details like country, ISO country code, email,
             * etc
             * 
             */
            private CasUser initialiseAdditionalUserDetails(String sAMAccountName, CasUser user) {
            try {
                SearchResult searchResult = searchExecutor.search(connectionFactory, "(sAMAccountname=" + sAMAccountName + ")", "c", "co", "mail",
                    "givenName", "sn", "displayName").getResult();
                LdapEntry entry = searchResult.getEntry();

                if (entry != null) {
                if (entry.getAttribute("givenName") != null) {
                    String firstName = entry.getAttribute("givenName").getStringValue();
                    user.setFirstName(firstName);
                }
                if (entry.getAttribute("sn") != null) {
                    String lastName = entry.getAttribute("sn").getStringValue();
                    user.setLastName(lastName);
                }
                if (entry.getAttribute("displayName") != null) {
                    String fullName = entry.getAttribute("displayName").getStringValue();
                    user.setFullName(fullName);
                }

                if (entry.getAttribute("c") != null) {
                    String isoCountryCode = entry.getAttribute("c").getStringValue();
                    user.setIsoCountryCode(isoCountryCode);
                }
                if (entry.getAttribute("co") != null) {
                    String country = entry.getAttribute("co").getStringValue();
                    user.setCountry(country);
                }
                if (entry.getAttribute("mail") != null) {
                    String email = entry.getAttribute("mail").getStringValue();
                    user.setEmail(email);
                }

                }

            } catch (LdapException e) {
                LOG.error(e);
            }

            return user;
            }
        }

And finally on the CAS Java clients .... I configure myCasAuthenticationUserDetailsService as below.....

        <beans:bean id="casAuthenticationProvider"
            class="org.springframework.security.cas.authentication.CasAuthenticationProvider">
            <beans:property name="serviceProperties" ref="serviceProperties" />
            <beans:property name="ticketValidator" ref="ticketValidator" />
            <beans:property name="authenticationUserDetailsService"
                ref="myCasAuthenticationUserDetailsService" />
            <beans:property name="key" value="notification" />
        </beans:bean>

        <beans:bean id="myCasAuthenticationUserDetailsService"
            class="com.jai.cas.MyCasAuthenticationUserDetailsService">
            <beans:property name="ldapUrl" value="${ldapUrl}" />
            <beans:property name="ldapAdminDn" value="${ldapAdminDn}" />
            <beans:property name="ldapAdminPwd" value="${ldapAdminPwd}" />
            <beans:property name="ldapUserBaseDn" value="${ldapUserBaseDn}" />
        </beans:bean>

This would retrieve all the needed attributes....
