And of course I can't login with the users I created in my ldap database.
Does any one know what to do or what I'm missing?

The accounts are not "synchronized" at all. Your accounts would be
stored directly in LDAP instead of on /etc/passwd. getent would search
through PAM to PAM's user info backend, which is in this case LDAP.
Before answering questions on how to set up login authentication against
ldap, we would need to know a few more details. What OS are you
running, and which release of that OS? Have you already used your
OS/distro native tools for setting up authentication and info through
LDAP? Red Hat Linux's "authconfig" sets up your authentication quite
easily (despite some disdain for it from our more seasoned admins).
Let me recommend a few of my favorite online resources for this. The
volume of material available through Google for basic introduction is
just huge. It is possible to retrieve just username and password from
LDAP and the rest of the information elsewhere, or vice versa. Get an
idea of what can be done, especially from the Frisch article, and we can
help more easily with more specific questions.
