An option for Apple File Service (AFP) allows a normal user to authenticate using an administrator's password. This can be useful when troubleshooting user-specific issues, such as permissions.
This feature can only be configured manually, by editing the AFP server's local NetInfo database. Use the steps below to enable or disable this feature:
1. Log into the server with an administrator account.
2. Open NetInfo Manager (/Applications/Utilities/).
3. In the NetInfo Manager navigation window, select the local directory, and go here:
/config/AppleFileServer
4. Look for this property:
attempt_admin_auth
5. To enable the feature, the value of this property must be 1. To disable this feature, the value of this property must be 0. Double-click the value to change it.
6. Save the changes in NetInfo Manager.
7. Using Server Settings, stop and restart Apple File Service.
