Modifying credentials

Edit online

You can modify existing credentials to provide access control for the discovery process.

About this task

To modify credentials, follow these steps:

Procedure

  1. In the navigation pane, click Discovery Credentials.
    The Discovery Credentials page is displayed with all the existing credentials listed.
  2. Edit the credential by clicking the Edit ( Edit) icon beside the credential.
    The Edit Discovery Credentials page is displayed.
    1. In the Modify Access Information pane, you can change the access information for this credential.
      Important: The access information that you specify must match the access information for the discovery target resource. If you change access information about the target resource, be sure to also change the associated TSA access information.
      Tip: The Discovery Credentials page displays the last time that the password was changed. If you regularly change the password on the target resource, you can use this information to make sure that you also change the password on TSA to match the new password for the target resource. For information about displaying the discovery credentials, see Displaying credentials.
    2. The Select Scope Set Restriction pane is used to specify whether a credential is limited to a single scope set or if it applies to all scope sets. If the Credential Type is Computer System and the Authentication type is PKI, then this pane is not displayed. PKI credentials must always be scoped to a single scope set.
      Tip: Creating discovery credentials that are restricted to a specific scope set can improve performance by reducing the number of credentials that are attempted for resources being discovered.
    3. The Restrict To Selected Scope Set pane is used to limit a credential to a single scope set. This pane is visible under one of these two conditions:
      • The Select Scope Set Restriction pane has Limit access information to specified scope selected, or
      • The Credential type is Computer System and the Authentication type is PKI.
      The credential is used only when discovering the selected scope set. This credential is not used with any other scope set. This method prevents invalid login attempts that can cause the user to be locked out of the account.
    4. If your credential type is Computer System, Computer System (Windows), SNMP, or SNMPV3 you can verify whether the credentials are correct. To test these credentials, enter an IP address or host name for the target you want to test the credentials with and click Test.
      Note: The host name you enter must not contain an underscore (_).
    5. Click Save.
      The changed credential is displayed in the Discovery Credentials page.
  3. To change the priority order in which a credential is used by TSA to access a resource, click either the Up arrow (Move up) icon or the Down arrow (Move down) icon beside the credential to move it up or down in the list.
    For information about how the order is used, see Discovery credentials.
    The Discovery Credentials page list is displayed again with the new order.
