security login modify

Modify a login method

Availability: This command is available to cluster administrators at the admin privilege level.

Description​

The security login modify command modifies the access-control role name of a login method. If the user is a member of multiple groups provisioned in the security login table, then the user will get access to a combined list of the commands authorized for the individual groups.

Parameters​

-vserver <Vserver Name> - Vserver
This specifies the Vserver name of the login method.
-user-or-group-name <text> - User Name or Group Name
This specifies the user name, Active Directory, LDAP, or NIS group name of the login method that is to be modified. A user name can be associated with multiple applications. If the user is a member of multiple groups provisioned in the security login table, then the user will get access to a combined list of the commands authorized for the individual groups.
-application <text> - Application
This specifies the application of the login method. Possible values include amqp, console, http, ontapi, rsh, snmp, service-processor, ssh, and telnet.
-authentication-method <text> - Authentication Method
This specifies the authentication method of the login method. Possible values include the following:
  • cert - SSL certificate authentication
  • community - SNMP community strings
  • domain - Active Directory authentication
  • nsswitch - LDAP or NIS authentication
  • password - Password
  • publickey - Public-key authentication
  • usm - SNMP user security model
  • saml - SAML authentication
[-remote-switch-ipaddress <IP Address>] - Remote Switch IP Address
This specifies the IP address of the remote switch. The remote switch could be a cluster switch monitored by cluster switch health monitor (CSHM) or a Fibre Channel (FC) switch monitored by MetroCluster health monitor (MCC-HM). This parameter is applicable only when the application is snmp and authentication method is usm (SNMP user security model).
[-role <text>] - Role Name
This modifies the access-control role name for the login method.
[-comment <text>] - Comment Text
This specifies comment text for the user account, for example, "Guest account". The maximum length is 128 characters.
[-is-ns-switch-group {yes|no}] - Whether Ns-switch Group
This specifies if user-or-group-name is an LDAP or NIS group. Possible values are yes or no. Default value is no.
[-second-authentication-method {none|publickey|password|nsswitch}] - Second Authentication Method2
This specifies the authentication method for the login method. It will be used as the second factor for authentication. Possible values include the following:
  • password - Password
  • publickey - Public-key authentication
  • nsswitch - NIS or LDAP authentication
  • none - default value

Examples​

The following example illustrates how to modify a login method that has the user name guest, the application ontapi, and the authentication method password to use the access-control role guest for Vserver vs:

cluster1::> security login modify -user-or-group-name guest
    -application ontapi -authentication-method password -role guest
    -vserver vs

The following example illustrates how to modify a login method that has the user name guest, the application ssh, and the authentication method publickey to use the access-control role vsadmin for Vserver vs:

cluster1::> security login modify -user-or-group-name guest
    -application ssh -authentication-method publickey -role vsadmin
    -vserver vs

The following example illustrates how to modify a login method that has the group name nssgroup, the application ontapi, and the authentication method nsswitch to use the access-control role readonly for Vserver vs. Here is-ns-switch-group must be set to yes:

cluster1::> security login modify -user-or-group-name nssgroup
    -application ontapi -authentication-method nsswitch -role readonly
    -vserver vs -is-ns-switch-group yes

The following example illustrates how to modify a login method that has the user name guest, the application ssh, and the authentication method publickey to use the second-authentication-method password for Vserver vs:

cluster1::> security login modify -user-or-group-name guest
    -application ssh -authentication-method publickey
    -second-authentication-method password -vserver vs

The following example illustrates how to modify a login method to have individual authentication methods that have the user name guest, the application ssh, and the authentication method publickey to use the second-authentication-method none for Vserver vs:

cluster1::> security login modify -user-or-group-name guest
    -application ssh -authentication-method publickey
    -second-authentication-method none -vserver vs
