Users can be added and modified in the Cerberus FTP Server user database by opening up the User Manager and selecting the Users tab.
Profile
Password The Password for the user.
Group A Cerberus FTP Server Group that this user belongs to.
Constraints
Anonymous If checked, the user password is ignored and the user can be logged in using any password.
Disabled Determines whether the account can log in or not. A disabled account cannot log in to the server.
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, e.g. 192.168.0.100 - 192.168.0.150, or a CIDR-formatted IP address 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
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
Multifactor Authentication (2FA) Determines if Two Factor authentication is allowed or required.
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.
Do not allow SSH SFTP logins (No 2FA): This option will not allow users to login via SSH SFTP when 2FA is enabled.
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
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.
Allowed Protocols
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:
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.

How do you setup a user to a specific port for FTPS explicit over TLS . eg port 989
Hello, Graham.
While you can't specify the port, you can controls which protocols a user is allowed to log in with.
If you wanted your user to use only FTPS:
Click on constraints
From here you can enable/disable the protocols you wish for the end-user to use. In your case, Only "AllowFTPS" would be checked.
We use the "allowed IP addresses" field as an extra security measure to only allow connections for that user from that IP adresses.
We also add those IP adresses in the IP Manager as allowed IP.
This works fine, but we now have an user with an IPv6 IP address. The IPv6 can be configured in the IP Manager, but not in the "allowed IP addresses" field under a user. We get the error message "Please enter one of more comma separated valid networkk addresses in doc-decimal, CIDR, or range notation.".
Is it possible to configure an IPv6 IP address in the "allowed IP addresses" field under an user? Or do we need to convert them to IPv4?
We use Cerberus Professional 11.3.5.0.
