If you want get a list of your users on Open Directory in Leopard Server, you need to use the dscl command from the Terminal. SSH to your server, and do a sudo bash or su - to get into root mode. Then you can run dscl directly with arguments, or, enter its interactive shell mode.
Listing Users with DSCL
Here is how to list users from the command line in Leopard Server:
myhost:~ root# dscl localhost list /Local/Default/Users
myhost:~ root# dscl localhost list /LDAPv3/127.0.0.1/Users
Or, go into interactive mode:
myhost:~ root# dscl
You should also be able to email the list to yourself, or, send it to a file:
myhost:~ root# dscl localhost list /LDAPv3/127.0.0.1/Users |sendmail email@example.com
myhost:~ root# dscl localhost list /LDAPv3/127.0.0.1/Users > /path/to/userlist.txt
An Easier Way with DSCACHEUTIL
There happens also to be a wrapper for this information, that makes things easy. You can use dscacheutil to get a list of users or groups and some relevant information. For example, use dscacheutil with the -q (query) switch and either user or group, like so:
dscacheutil -q userdscacheutil -q groupThe output looks like this:
bash-3.2# dscacheutil -q username: _amavisdpassword: *uid: 83gid: 83dir: /var/virusmailsshell: /usr/bin/falsegecos: AMaViS Daemonname: _appownerpassword: *uid: 87gid: 87dir: /var/emptyshell: /usr/bin/falsegecos: Application Owner
Hope this helps someone. Enjoy!
