Pluck out the actual LDAP code into IRB and see if it works. I've not
had experience passing Net::LDAP.new a hash, I've only ever assigned
values to its attributes after creating the instance, like:

ldap = Net::LDAP.net
ldap.host = 'http://localhost/
ldap.auth "%s@localhost" % user, pass
ldap.bind

Try that if your way fails in IRB.

It will definitely work with the hash assignment - I do it here with
ActiveDirectory

I think Varun is missing the port setting though.

Varun, do as Matt says, try it in IRB until you get it working, also,
pass the port parameter into the hash after the address. It can't
hurt.

The port setting should default to 389 if you don't set it. In addition to
the IRB suggestions, Varun should also try to telnet from his machine to
192.168.0.3, port 389 to see if he has connectivity in the first place.

Your "problem" is that your username and password are incorrect in the
LDAP server. You can bind without any authentication so the Ruby
Net::LDAP connection, go read up on LDAP, it is not a Ruby problem.

The correct format for the #auth call would be as follows:

ldap.auth "(e-mail address removed)", "password"

Not:

ldap.auth "%sldap://ldapservername.com"%'username', 'password'

Note that you lack an @ sign and you've put the ldap protocol in the
string. Instead, what's required is the format: (e-mail address removed)
with username being replaced with the correct username.

This is a shorthand way to write your username... alternatively you
can supply a full DN as long as you provide the correct password too.

Experiment with it. We cannot solve your problem, we can only help you
and possibly recognize where you've made mistakes or overlooked a
small details; it is up to you to solve your issue.

You might need to check out your configuration of the LDAP server,
which, unfortunately, I have absolutely no experience with.

There should be plenty of examples around to clarify.

I'm not sure how much more assistance I can be for you. At the very
least, what's the exact error message you're receiving?

Hello Matt,
Actually i made one function like this.And this function returns me true.
Then what's mean of this function means my connection to ldap server has
been establish or not.
Please guide me and if connection is established then how can i
authenticate username and password through ldap server.
Can i do like this..
filter = Net::LDAP::Filter.eq('uid', username)
ldap.searchfilter => filter) {|entry| username = entry.dn}
Please guide me i am confused in this LDAP connection.
Looking for ur reply.
Thanks
