by thiagu.m
hi every one
this is my project environment
jboss seam: 2.1.0.A1

When more than one person try to access that particular page at a time
I got following exception

[JBoss Portal] - Re: How to get Ldap informations?
by rammyramkumar
hi
this is my configuration in login-config.xml file . it is working for me. May be this will be of some help to you.
<!DOCTYPE policy PUBLIC

this will enable you authenticate against LDAP using the Jboss portal login.
Code in my part is
/**
*
* @return Map of Identity Modules
*/
public Map<String,Object> getLDAPModules()
{
Map<String,Object> modulesMap = new HashMap();
if (!checkConfig.equalsIgnoreCase("true"))
{
try
{
UserModule usermodule = (UserModule) new InitialContext().lookup("java:/portal/UserModule");
RoleModule roleModule =(RoleModule) new InitialContext().lookup("java:/portal/RoleModule");
UserProfileModule userProfileModule = (UserProfileModule) new InitialContext().lookup("java:/portal/UserProfileModule");
MembershipModule membershipModule = (MembershipModule) new InitialContext().lookup("java:/portal/MembershipModule");
modulesMap.put(User.USER_MODULE, usermodule);
modulesMap.put(User.ROLE_MODULE, roleModule);
modulesMap.put(User.USER_PROFILE_MODULE, userProfileModule);
modulesMap.put(User.MEMBERSHIP_MODULE, membershipModule);
return modulesMap;
}
catch (NamingException e)
{
e.printStackTrace();
}
catch(Exception e){
e.printStackTrace();
}
}
return null;
}
// this will fetch you the Identity Modules and using this you can get the necessary details from LDAP using the methods available in each Modules.
Good Luck...happy coding
