Use this script to import users into an Open Directory domain on OS X Mavericks Server with users in a CSV. The Users.csv file is an example file to show you the structure expected.

#	Import Users into an Open Directory Domain
#	by Dan Barrett
#	http://yesdevnull.net

#	You may need to change the details below depending on your configuration
#	and settings

#	Arguments:
#	* 	Path to the CSV

#	CSV format should be:
#	+------------+---------+------------+----------+
#	| First Name | Surname | Student ID | Password |
#	+------------+---------+------------+----------+

#	Note: You must ensure that the line endings for the CSV are Unix (or CRLF)
#	and you have an empty line on the last line

#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*

#	This will work if you're running it on the Directory Service Domain, change
#	it if you're running the script on another bound machine
directoryDomain="/LDAPv3/127.0.0.1"
#	Username of a directory administrator
directoryUsername="masterdiradmin"
#	Password for the above directory administrator
directoryPassword="masterpass"

#	Username for an administrator of the server ( aka Local Domain or . )
#	(for local groups like com.apple.access_radius)
serverUsername="serveradmin"
#	Password for the above server administrator
serverPassword="serverpass"

#	Primary Group ID ("Open Directory Users" group on OS X Server is 20)
primaryGroupID="20"
#	NFS Home Directory (leave this as /dev/null if the users are services only)
nfsHomeDirectory="/dev/null"
#	Shell path for the user
userShell="/usr/bin/false"
#	Domain for the email address (e.g. pretendco.com, apple.com)
emailDomain="pretendco.com"

#	List of local groups to add the user to (separate each group with a space)
localGroups=( com.apple.access_radius com.apple.access_afp com.apple.access_addressbook )
#	List of network groups to add the user to (separate each group with a space)

#	This function will get the most recent UniqueID for the directory domain,
#	then increase by 1 for the next user to add

Users.csv

Great script, I modified it for our server. Just a weird issue I'm running into; the home directory and the owner of the directory seems to be diradmin, when it should be the user. Any suggestions would be much appreciated.

this was great! Thanks for keeping this around
