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.
