I am trying to bind a Lion 10.7 mac to Active Directory

I am trying to bind Lion mac using the Directory Utility. It never gets past "getting AD domain info" and eventually fails with "authentication server coud not be contacted." Anyone else having problems joining Lion mac to AD?

Intel Dual-Core, Mac OS X (10.7)

we are having the same issue at a small local college I work at. We have around 200 Mac's on campus mostly running 10.6.8 they are all currently bound to the AD and the OD servers it use to be that after binding I could go in and make a AD group administrators on the machines so once a member of the group would log in they would automatically become an admin this use to work but for some strange reason this policy stopped working on the Mac's it will works on the 4000 windows machines...any idea's?

May or may not be related, but I'll add my observations:


fqdn (DNS) is mostly not going to work with client Macs in an AD environment.


Have you ever used ARD to see your Macs in an AD enviroement, and notice the name of the Mac under the DNS info column, is almost always screwed up, some weird name or incorrect name appears. (could be DNS, or more likely a major bug in Apple Remote Desktop, that Apple has yet to fix for the last several years).


If you are using a Mac OS X client machine in this environment, the DNS just does not know what the name of the Mac is, there will be no DNS name resolution.


If you have a Mac OS X Server in this environment, you give the IP address to your DNS admin, with its name and you have him enter a record into the DNS.


In the terminal on OS X Server, you then use the changeip -checkhostname <osxserverhostname>


You should get, the names match there is nothing to change, message.


Finding that Mac OS X Server by name, will now always work: filesharing, ssh, web URL's, you name it.


But using FQDN names of client Mac OS X machines, is just not going to work, unless there is a dns record entered into the DNS, and for DHCP, concerning mac or windows clients, that just does not happen.


If you want to get to a Mac OS X client via sharing, you just have to know the IP address.

Is there a reason you need to use OD. In my experience is it just simply a "bag of hurt".


You have to bind the client Macs to both AD and the OD server (that is bound to AD), assuming this OD Server is also correct and stable.


If the OS X client loses only one of the AD or OD bindings, the Mac cannot log in. That is ridiculous.


Why would a Mac admin or anyone want to introduce these dependencies.


I have seen it a ton of times.


And then there could be issues with Kerberos.


If it was me, and I had to bind to AD. Just use Apple's built in AD plugin in (Directory Utility), by itself.


There is very little reason to use OD in AD, unless one wants Managed Prefs. Are you kidding. Apple's Managed Prefs are more suited for a school lab of 50 Macs or so, they are global and pretty weak. I see no use for it. If you want true policies (MSs Group Policy) Centrify is pretty good.


AD binding does work in 10.6.8 in this manner pretty well.


But as I have mentioned here, in 10.7 AD binding was broken on shipping of 10.7, it seems to be working once again as of 10.7.2.


I am trying to to figure out for the life of me how AD binding of a Mac is even relevant anymore. It makes no sense to do it. We no longer do it, why.


If users need to get to areas on the network, shares, etc, they simply enter their AD credentials.


If one really needs AD binding for some reason (I still cannot fathom), consider using Centrify Express, which works pretty well, at least they are on top of it and are proactive about it always working.


It seems obvious to me AD binding is simply not a priority at Apple, it never has been, and is it even relevant today.

OX Lion 10.7.2 doesn't like talking to SBS 2003/08. Some say it is an AD bind issue. I can tell you it isn't - well from what I have seen it is Java related. You will need to install/update Java SE http://support.apple.com/kb/DL1421 and reboot your machine. Bootnote - Java wasn't included with the LIon install - it's an add on.


I did read that 10.7.3 fixed known AD binding issues with SBS - but cannot confirm right now.
