18 CPS Installer/User Guide
A user’s access rights are determined from the authentication method used. SSH key authentication
always uses the access rights from the local user database. Depending on the server authentication
method specified with the Server Security command, SSH password authentication will use either
the access rights from the local user database, the DSView software server or the values returned by
the RADIUS server.
With either of the “or” methods (PW|KEY and KEY|PW), the user access rights are determined
from the method used to authenticate the user.
With either of the “and” methods (PW&KEY and KEY&PW), the user access rights are
determined from the first method specified. If PW&KEY is specified, the access rights from the
password authentication will be used. If KEY&PW is specified, the access rights from the key
authentication will be used.
For more information, see Using Authentication Methods on page 24.
SSH user keys
A user’s SSH key is specified in a User Add or User Set command. You may define a key even if
SSH is not currently enabled. The key may be specified in one of two ways:
• When using the SSHKEY and FTPIP keyword pair to define the network location of a user’s
SSH key file, the SSHKEY parameter specifies the name of the uuencoded (Unix to Unix
encoded) public key file on an FTP server. The maximum file size that can be received is 4K
bytes. The FTPIP parameter specifies the FTP server’s IP address.
When this method is specified, the CPS appliance initiates an FTP client request to the
specified IP address. The CPS appliance then prompts the user for an FTP username and
password for connection. When connected, the CPS appliance will GET the specified key file
PW|KEY or KEY|PW
SSH connections will be authenticated with either a username/password or an SSH
key. If a user has only a password defined, that user must authenticate an SSH
session with a username/password. If a user has only an SSH key defined, that user
must authenticate an SSH session using the key. If a user has both a password and
an SSH key defined, that user may use either a username/password or the SSH key
to authenticate an SSH session. This method allows the administrator to define how
each user will authenticate an SSH session based on information provided in the
User Add/Set command.
PW authentication will be local, RADIUS or DS as specified in the Auth parameter of
the Server Security command. Key authentication is always local.
PW&KEY or KEY&PW
SSH connections will be authenticated using both a username/password and an
SSH key. With this method, a user’s definition must include a password and SSH key
information for that user to authenticate an SSH session.
PW authentication will be local, RADIUS or DS as specified in the Auth parameter of
the Server Security command. Key authentication is always local.
