I have to agree with the previous poster, this tutorial is too light on information. I followed all the instructions to the letter and it just wouldn't work. I kept getting:

ldap_bind: Can't contact LDAP server (-1)

No matter what I put into the /etc/hosts.allow and restarted the networking/rebooted. No idea how to fix it. Will do some more research.

Questions I'd like to see answered would be how would I add a user? Do I re-run the ldapadd command with the users name? Do I have to create an ldif file?

 I appreciate the effort, LDAP seem quite complicated to configure and this is possibly a good start, just needs some fleshing out.

 Thanks
