Unable to log in to open directory account

Open up terminal and try:

$ dscl . -list /groups GroupMembership

You should get a list of users along with which group they belong to. You should look for user/admin accounts including the one you recently made; This command will show you all users with the recently created one most likely near the bottom:

$ dscl . list /users

To get information about a user:

$ dscl . read /users/foo

Which will verbosely spit out all of the basic information, yielding this information near the bottom:

NFSHomeDirectory: /Users/foo

if you want to delete a user:

$ sudo dscl . delete /users/foo

asta la bye-bye! from there you can decide whether or not to delete ex-users directory.

I was able to figure this out a while ago, but I realized I only posted the answer to my question on Serverfault. Here's the solution for this:

I ended up setting up Lion Server at my house, creating an Open Directory user with a remote home directory, and looking in the Directory Utility to see what the actual keys were set as. I was then able to use Directory Utility on the client's computer to set the keys manually and it worked perfectly.

Here are the keys you need to set assuming the server's hostname is server, and the directory is /Users/test on the server:

key: HomeDirectory

val: <home_dir><url>afp://server/Users</url><path>test</path></home_dir>

key: NFSHomeDirectory

val: /Network/Servers/server/Users/test
