One particular user cannot seem to log onto any of the Apple PCs or laptops on my network. The machines are running Snow Leopard. Other users can log in and authenticate just fine. When this one user attempts to log on, after a few seconds, the screen shakes as if the password is wrong. What's causing this, and how can I resolve it?
The login window doesn't give much in the way of indications why a user isn't allowed to log in -- it shakes its "head" no, but doesn't say why. Sometimes you can find something in the system.log file (view it with the Console utility) about what the problem was, but generally not.
My standard approach to narrowing down where errors like this are coming from is to test the critical parts of a network login (user info lookup, authentication, and home directory mount) by hand and watch for informative errors:
Log in as a local user (not a network user) on a client computer, and open the Terminal utility.
Run the command
There are actually two different modes of authentication, and you should test them both. First, check Password Server-style authentication with the command
Next, try to get a network authentication (Kerberos) ticket with the command
If those work, use the Finder's Connect to Server (Command-K) feature to try to connect to the server; enter the server's full domain name in the Server Address field. You should not be prompted for a name and password (Kerberos authentication should be automatic after the
If none of that shows any problem, you've got something more obscure going wrong. One other thing to try is to make sure the user's home folder settings are configured correctly: use WGM to switch the user's home folder to "(None)", save, then set it back and save again.
