• CA Identity Suite

Issue/Introduction

We can login via SSH as config user to vApp node, however , for example, when navigating under /opt/CA/IdentityManager/Provisioning directory I am getting "Permission Denied." error.
Is there any other users config user can switch to in vApp?

Environment

vApp (Virtual Appliance) 14.x
CA Identity Suite

Resolution

Yes, config user can switch to the following users
   a. dsa (when CA Directory, i.e. User Store (US) or Provisioning Server (PS) component is deployed)
   b. imps (when Provisioning Server (PS) component is deployed)
   c. oracle (when embedded Oracle Database (DB) component is deployed)

To switch to a different user, config user should run the following command
      su - <username>

E.g.
      su - dsa
