Active Directory (AD) Users

Setting up your Domain

The first step in configuring your AD users, will be setting up your domain. When you first go into AD users, you will see this page.

 

To begin configuring your domain you will want to select 'New Domain'. For more information on how to configure AD within Cerberus, please see Setting up Active Directory Authentication in Cerberus FTP Server. This document will explain each of the tabs you find within the 'AD Users' tab.

 

After configuring your domain, we should see a user list populate when we navigate into 'AD Users', with the selected domain shown at the top.

Individual AD User Settings

Just like Cerberus native users, AD users share a similarly structured list of tabs to configure your user. If you attempt to change any fields, remember to click the 'Update' button. All fields other than the Primary/Secondary group are read-only, if you encounter a greyed out field, it is driven by the AD attribute for that user.

 

Profile tab.

Username The username this account will use to log in. (Required)
Email An email address to associate with the user account. This email address may be used as the 'from' address when creating public shares and the 'to' address when sending password reset emails. (Optional)
First Name, Last Name, Telephone, Mobile Optional Information fields for the user
Description A description field for the user account
Primary Group A Cerberus FTP Server Group that this user belongs to. All of the user's settings are overridden by the settings of the Primary Group.
Secondary Groups

Additional Groups the user is assigned to in order to add access to additional virtual directories. User settings are NOT overridden by Secondary Groups, they merely grant the user access to the virtual directories assigned to the group.
Last Login Time

The time that the user last logged into Cerberus FTP Server
Last Login IP

The last recorded IP address that the user logged in from.
Password Last Changed

The date when the user's password was last changed.
Creation Date

The date when the user was created in Cerberus FTP Server

 

Constraints tab.

Password Never Expires If checked, the user's password never expires.
User Can Change Password Controls whether a user can change their password through the HTTP/S web client or through SSH SFTP or FTP commands.
Disabled Determines whether the account can log in or not. A disabled account cannot log in to the server.
Anonymous If checked, the user password is ignored and the user can be logged in using any password.
Max Logins The maximum number of connections this user can make to the server at the same time.
Disable Date If a date is set here then the account will become disabled after the date specified.
Note: The granularity of the timer is 30 minutes. The account will be disabled within 30 minutes of the time set.
Max Upload Filesize This field can be used to limit the maximum size of an uploaded file. This value defaults to unlimited. The file size is specified in bytes. Specify 0 or any non-positive value to reset the maximum file size to unlimited.
Allowed IP Addresses A comma-separated list of IP addresses that this user can log in from. If no IP addresses are specified then no per-user IP address filtering is enforced. IP addresses can be specified as a single IP, a range of IP addresses separated by a dash with no spaces, e.g. 192.168.0.100-192.168.0.150, or a CIDR-formatted IP address range. Adding spaces before and after the dash will invalidate the IP range. Multiple formats can be combined, with each single IP or range separated by a comma. Note, global IP address deny lists or allow lists are always enforced first, regardless of this setting.

 

Authentication tab.

SSH Authentication Method Determines the authentication requirements for logging into an SFTP interface. Valid options are:
  • Password Only: Require only a password for authentication.
  • Public Key Only: Require only a valid public key for authentication
  • Public Key and Password: Require both a valid public key and a valid password for authenticating a user.
  • Public Key or Password: Require either a valid public key or a valid password for authenticating a user.

For more information on SSH Public Key Authentication, please refer to our support article

Configuring a user for SSH Public Key Authentication

Allow 2 Factor This option allows users to set up 2FA if they choose to
Require 2 Factor for HTTP/S This makes 2FA a requirement when using the HTTP/S web client.
2 Factor for SSH SFTP/SCP This drop-down menu will determine how Cerberus FTP handles 2FA behavior for users when using the SFTP protocol.  The options are as follows:

 
  • Ignore: Cerberus will bypass the use of 2FA for SSH and SFTP/SCP protocols, regardless of the status of 2 2-factor authentication. In this case, the user will not be required to enter 2FA credentials. Please note, this is not a recommended option unless absolutely necessary. A “warning badge” will be visible in the configuration page and the report page if this setting is made for the user.
  • Require When Status Enabled: Cerberus will require 2FA for SSH and SFTP/SCP protocols provided the status of 2 Factor Authentication is “Enabled”. In other words, the user will be required to enter 2FA credentials if the status of 2FA is enabled. If the status of 2FA is disabled, the user will not be required to enter 2FA credentials.
  • Require: Regardless of the status of 2 Factor Authentication, Cerberus will expect 2FA authentication for that user. If the status of 2 Factor Authentication is “Enabled”, the user will be able to authenticate via 2FA. If the status of 2 Factor Authentication is “Disabled”, the user won’t be able to authenticate as they won’t have the 2FA credentials but Cerberus will still expect them for successful authentication.

Do not allow FTP/S logins (No 2FA)

 This option will not allow users to login via FTP/S when 2FA is enabled.
2 Factor Authentication Status Shows whether 2FA is currently enabled on the account.

Enabled User has enabled 2FA for their account. Once two-factor authentication is enabled for a user account you can disable it at any time by pressing Disable 2FA

Disabled User does not have 2FA enabled for their account.

For more information on 2FA (2 factor authentication), please refer to our support article on How do I manage 2FA for an AD User in Cerberus?

 

Allowed Protocols tab.

 

Permitted Login Protocols Controls which protocols a user is allowed to log in with. If a protocol is not checked then the user will not be allowed to log in using that protocol.
FTP Only Settings These settings only apply when the user logs in using FTP.
Require Secure Control If enabled, this user can only log in to the server using a secure TLS/SSL encrypted connection.
Require Secure Data If enabled, file transfers will only be allowed over secure TLS/SSL encrypted connections.

 

Virtual Directories Tab

See Adding a virtual directory to a user account for detailed information on how to add virtual directories to the user account.
