Mac clients on Server 2008 R2 domain
We have a suite of Macintosh clients running OS X 10.5.8
Until we upgraded our Active Directory domain to Windows Server 2008 R2 native mode and enabled LDAP encryption between servers and clients, it worked fine.
Now the clients won't log on to the network - try to use AD user accounts and the macs just "shake their head" at users.
I suspect this is a LDAP encryption issue rather than something to do with the upgrade to 2008 R2 native mode itself, but as both were performed at the same time it could be either.
Although we can log on locally to the macs and unbind them from their current domain settings, we can't seem to re-add them. Follow any instructions I can find, plus Apple's "Good Practices" pdf file, and nothing seems to work.
Any suggestions as to setting up Macs to work with a domain where LDAP Encryption is enabled? Is it just a case of obtaining a certificate from the CA we have on our network and ticking the "Use SSL" box when binding?
