Using su/sudo

Thesu command (as used by Serena Release Automation) enables a user to start a shell as another user (process steps can be considered individual shells). When you configure a process step (see Process Editor), you can tell Serena Release Automation to use impersonation for the step. By default,su is used but you can usesudo instead. To configure impersonation, you supply the user name required by the target host. When the impersonation-configured process step runs, thesu orsudo command runs the step as the impersonated user. Each step that needs user impersonation must be configured independently.

Beforesudo can be used, impersonation privileges must be defined in the/etc/sudoers file. When you configuresudoers, ensure that the impersonating user does not have to supply a password. Typically, you would configure the/etc/sudoers file like this:

Defaults:X !requiretty

X ALL=(Y) NOPASSWD: ALL

where X and Y are user names. Configured this way, user X can run any command as user Y without supplying a password.

su andsudo maintain a record in the system logs of all of their activity.su can be used without configuring thesudoers file. For information aboutsu/sudo see the Unix/Linux documentation.
