Java login through LDAP

September 26Hits:1
Advertisement

I am starting to write an application for our office and the first step is authentication through LDAP where all users already exist. Everything I need is a code in Java to check if the pair <nick,password> is right. Google found me many links, but I think that I will find here the most sofisticate, short and up to date solution (I don't want to read all articles like 2 whole days to do something so simple).

I have written many dkBs of code in C++, but in Java I am total noob and I haven't coded anything with LDAP yet so try to be simple if speaking in Java and LDAP terms if possible.

Stack Overflow is the right site. In the meantime, using the UnboundID LDAP SDK:

try {
    LDAPConnection ldapConnection = new LDAPConnection(host,port,bindDN,bindPassword);
} catch (LDAPException ex) {
    handle exception ...
}

or

try {
    LDAPConnection ldapConnection = new LDAPConnection(host,port);
    SimpleBindRequest bindRequest = new SimpleBindRequest(bindDN,bindPassword);
    final BindResult bindResult = ldapConnection.bind(bindRequest);
} catch (LDAPException ex) {
    handle exception ...
}

for simple BIND requests. SASL binds are also handled by the LDAP SDK.
