    I have the exact same problem.  I get this message in Console:

     

    AppleIDAuthAgent: Unable to determine if Apple ID certificate is trusted.

    com.apple.message.domain: com.apple.coreservices.appleidauthentication.checkAccountCertificateTrustRecove rableTrustUnspecified

    I found a work Around -

     

     

    Turned on file sharing , went to Advanced Tab and

     

    turned on SMB (Windows Sharing),

     

    Turned OFF (Unchecked) AFP

     

    I can now connect to all Macs.

     

    It definetly looks like an AFP issue.

     

    See my original Issue at:

    I don't know if this will help any of you but I got connections working by:

     

    1. making a new account on my tower computer (Not sure if that did anything)

    On both computers:

         2. Deleting all the shared folders in the sharing preferences

         3. Then editing the drives/folders settings in get info ie. adding administrator read write at the bottom

         4. re-added the folders/drives in the sharing preferences

     

    I also changed the user name of my account on my mac book, but I doubt that had anything to do with it.

     

    To note the disabling AFP and leaving SMB on worked for me, but messed up my time machine backup, so i did all this stuff.

    Similar to what you did, I followed what I found on this post:

     

    http://swish-movement.blogspot.com/2011/07/afp-failing-between-osx-lion-machines .html

     

    I use Mobile Me (Back to my Mac) to connect, which always seems to give full access to the file system anyway, so removing all the shared folders did not change this, but did restore file sharing somehow

    Nope, didnt work for me. I disabled all sharing, removed all shares from the list, reenabled SMB only shareing on one folder, and I was still unable to mount it properly. However, my linux desktop could mount the devault volume share that appeared, I was able to authneticate with my admin user but I could not open any files on it - Nautalus reported "Error - unsupported feature".

    Found this on another board....

    This problem is very real, but it is *NOT* an OS X Lion (10.6.8) issue. I think it is an Airport software issue. I just had the very same problem appear under Snow Leopard 10.6.7 on two separate LAN WiFi networks, one in Albuquerque and another in Sacramento. I've been able to replicate the problem on the two different networks:

     

     

    Albuquerque (new Airport Extreme with Qwest/Motorola DSL modem)

    1. Upgraded Airport Utility to v7.5.2.

    2. Added a new Airport Express to extend (5GHz) Airport Extreme signal for network 1 (Albuquerque).

    3. WiFi network worked for a few minutes and then ground to a halt. WiFi dead on Macs, Windows 7 and Vista PCs, iPhone 4s and iPads.Network down for a couple of days, trying to fix it. We finally had to disconnect the Airport Express. Choosing "extend a network" is the problem...

     

     

    Sacramento (2nd generation Time Capsule with old, Comcast Scientific Atlanta or new RCA DOCIS 2.0 modems)

    1. Upgraded Airport Utility to v7.5.2.

    2. Added a new Airport Express to extend (5 GHz) Time Capsule signal for network 2 (Sacramento).

    3. WiFi network worked for a few minutes and then ground to a halt. WiFi dead on Macs, iPhone 4s and iPads. After a few minutes, even Ethernet access died — the router kills the DSL or cable modems since they get caught in a communications loop. This network also went down for a couple of days. We finally had to disconnect the Airport Express. Choosing "extend a network" is the problem...

    4. To test this theory, I reconfigured a second Time Capsule on this network from Wireless "Off" to extend the network.

    5. Same problem — network fails and the main DHCP router can't communicate with the cable modem. Even Ethernet died.

     

     

    When this occurs, the network slows to a crawl. Web pages stop loading or take minutes to load. You can't communicate with the "extended" routers at all — they get stuck while Airport attempts to read or save the Airport configuration file. Disconnecting them is the only option. Even resetting these devices doesn't work properly.

     

     

    Three different people configured these networks and we all had the same problems. Apple, you have a problem.

    No need to disable AFP. This is resolved by simply unsharing your home folder (presuming it is shared).

    The home folder is automatically shared in Lion.

    BigChops: This works too. The home folder was shared by default. Many thanks again to everyone who has contributed

    This worked for me too. So simple when you know how. 1 minute's work solved it after spending all day yesterday, playing around with every other setting I could think of and trying every different method of getting my Macs to talk to each other.

     

    Many thanks!
