Import users and groups from a file in macOS Server
You can import users and groups from character-delimited text files, which is an easy way to quickly set up accounts.
You can Export users and groups to a file in macOS Server or use the dsexport command-line tool to create character-delimited text files of accounts on your network server. For information about how to use dsexport, enter man dsexport in Terminal.
Passwords aren’t included in the export files generated by dsexport, but you can edit the file to include them. Otherwise, you’ll need to assign passwords to users after importing.
In the Server app
sidebar, select Users.Click
and choose Import users, then select the file to import.Select the directory domain from the Directory pop-up menu where you want the new users to reside.
If necessary, enter an administrator name and password for the file and select a user template.
Click Import.
You can also use the dsimport command to import users from a file. Users imported from a file don’t have access to services until you grant them access. For information about granting users access to services, see Define service access by users in macOS Server.
