You can be customize the credential checkout feature for the applications such as Salesforce and so on.
To enable credential checkout for LDAP, Active Directory, SAP, ESXi, you can import the respective policy template. When you import the policy template, all the components required for configuring a credential checkout, such as resource and rule are added with default values. You must customize these according to your requirement.
To enable credential checkout for an application whose policy template is not available, you need to add the application server as a resource in the credential vault and add a credential checkout rule. For information about adding a resource, see contextual help. For information about adding a rule, see Adding a Permission in Access Control or Adding a Rule in Command Control.
