Mac OS X 10.6.8, Snow Leopard, and ".local" domains

Updated December 19, 2011

Apple has recently made a significant change in how the OS handles requests for ".local" name resolution that can adversely affect Active Directory authentication and DFS resolution.

We have determined that the issue is directly related to a change in the Mac OS X 10.6.8 update that only affects ".local" domains.  When processing a ".local" request, the Mac OS now sends a Multicast DNS (mDNS) or broadcast, then waits for that request to timeout before correctly sending the information to the DNS server.  The delay caused by this results in an authentication failure in most cases.

We have determined a possible workaround to the problem (only on Mac OS X 10.6.8, Snow Leopard) , but there will still be a delay when authenticating:

    Log in as a local admin
    Launch the Terminal
    Enter the following (followed by the 'return' key):

defaults write /Library/Preferences/com.thursby.CIFSPlugin "LDAP Connect Timeout" 30

    Reboot

This issue also affects Apple's built-in Active Directory.  Apple's only solution thus far is located here.

As soon as we have any newer information, this entry will be updated.
