It is required to specify the NOPASSWD qualifier within the "sudo" configuration file, as shown here: Sudo File Configuration Examples for SAP ASE Environments. This ensures that the "sudo" command does not demand the entry of a password, even for the "display permissions" (i.e. "sudo -l") command.
Delphix issues "sudo -l" in some scripts to detect if the operating system user has the correct sudo privileges. If it is unable to execute this command, some actions may fail and Delphix will raise an alert suggesting it does not have the correct sudo permissions. Restricting the execution of "sudo -l" by setting “listpw=always” in the “/etc/sudoers” file when the Delphix operating system user is configured to use public key authentication will cause the Delphix operating system user to be prompted for a password which will fail certain Delphix actions. Use a less restrictive setting for listpw than "always" when the Delphix operating system user is using public key authentication.
