Examples:
createmobileaccount -n jsmith
createmobileaccount -v -P -n jsmith
createmobileaccount -vsxn jsmith -h /Volumes/HD3/jhome
createmobileaccount -vsxn jsmith -h /Volumes/HD3/jhome -u nfs:/server.apple.com/bigs/homes -t myusers/macos/jhome

Notes:
- createmobileaccount must run as root.
- If you do not specify a password, the account's cached password will be created during the account's first log in.

createmobileaccount -vsxn COYOTEID -h /Users/COYOTEID

The OpenDirectory cached the users password locally. To delete cached information that is no longer valid other than to delete the information, we had to delete the user while keeping the users homedirectory.

sudo dscl . -remove /Users/[username]

This will remove the user [username] from the userlist but keeps the homedirectory as it is.

Note: You should only do so with a cached mobile user!!!! To find out about your cached users run this snippet:

dscl . -list /Users AuthenticationAuthority | grep LocalCachedUser | awk '{print $1}'
