I am preparing to setup a small network with single sign on capability provided by and OpenLDAP server that runs on OpenBSD 5.3. Currently, I am able authenticate an Ubuntu 13.04 client against the server, but for some reason I am having trouble authenticating on my OS X client. I've used the directory utility to connect to my server, and it seems that I am able to successfully communicate with the server, but not authenticate. I know this may seem vauge, but I am new to administering OS X. Help is appreciated.

I'm fighting through this myself as we speak. One of the things you must add on the Ubuntu side, according to my research, is a Kerberos KDC. There is some great documentation on setting one of these up here: .

While Kerberos gets along very will with OpenLDAP, and I would recommend it, it is by no means required. – 84104 Oct 18 '13 at 19:59
The OP asked how to authenticate using Apple's Directory Utility, which I am still struggling with. DU attempts to do a SASL bind. From the error logs, I'm still trying to determine which mechanism is used. Any advice would be appreciated. – Ned W. Nov 8 '13 at 2:58
