You can remove saved host credentials from the persistent cache using the Host Credentials setting.
To remove saved host credentials
The mangement console clears the credentials for the selected host(s).
These are the System Preferences:
Use the General system settings to:
To ensure uniqueness of hosts, by default, the mangement console prevents you from adding hosts with the same SSH host key. Since a host can have more than one resolvable DNS name and multiple IP addresses, there should only be one SSH host key returned for whichever DNS name or IP address you use to access the host. However, if you want to add hosts with the same SSH key to the mangement console, you can enable this setting. Enable (or disable) the Duplicate SSH host keys setting in System settings.
Note: If you enable Duplicate SSH Host Keys, you can profile multiple hosts that share the same public key. Once this is enabled there will be no way to validate if a host has been added more than once. You could potentially add a host multiple times under alternate IP addresses or DNS names. If this happens, duplicate users and groups would be visible, and reports will show redundant data. One Identity recommends that you NOT enable this feature to ensure that each host has a unique public key. However, it might be desirable to enable this feature if you want to add multiple hosts that are used for replication where each host shares the same public key.
To add hosts with the same SSH host key
Log onto the mangement console using the supervisor account or an Active Directory account with rights to change System Settings; that is, an account in the Console Administration role.
From the top-level Settings menu, navigate to the General settings.
Select the Allow hosts with the same SSH host keys to be added to the console option.
Click OK to save your selection and close System Settings.
