Sudo command is rejected by Safeguard for Sudo

Safeguard for Sudo might reject a sudo command. For example, let us assume you ran the following command:

$ sudo id

and received output similar to the following:

<user> is not in the sudoers file. This incident will be reported. 
Request rejected by Safeguard

There are several things you can do to troubleshoot this issue.

To troubleshoot why a sudo command is rejected

Run the following from the policy server:

  1. To ensure the user has permission, run the following as a sudo administrator. 
    # sudo –U <username> -l
  2. To check that the policy is located at /etc/opt/quest/qpm4u/policy/sudoers is the current version, run: 
    # pmpolicy masterstatus

    In the output, ensure that Current Revision and Latest Trunk Revision have the same number and Locally modified is "No".

  3. To ensure the user has permission to run the command, check the /etc/opt/quest/qpm4u/policy/sudoers file and verify the user’s (or group’s) permissions: 
    # cat /etc/opt/quest/qpm4u/policy/sudoers
  4. To verify that the policy server is working properly, enter: 
    # pmsrvcheck

    This command returns output similar to:

    testing policy server [ Pass ]

    From the command line, enter:

    # pmsrvinfo

    This command returns output similar to:

Sudo policy is not working properly

If your sudo policy is not working as expected, use these troubleshooting steps:

  1. To verify the version of sudo on your host: 
    # sudo –V
  2. To verify that the Sudo Plugin host is joined to the policy server, run: 
    # pmplugininfo
  3. To see what commands the user is allowed to run: 
    # sudo –l –U <username>

    This command returns output similar to:

    Matching Defaults entries for testuser on this host: 
      log_output 
User testuser may run the following commands on this host: 
      (ALL) /opt/quest/bin/
  4. On the policy server, use the pmpolicy utility for managing the Privilege Manager for Sudo security policy.
    1. To verify that you have the correct version of the policy, run:
      # pmpolicy masterstatus

      Ensure that Locally modified in the output is No.

    2. To update the version of the policy, run: 
      # pmpolicy sync
    3. To verify there are no syntax errors in the policy, run: 
      # pmpolicy checkout –d <dir>
  5. On the Sudo Plugin host, use the pmpolicyplugin utility to display the revision status of the cached security policy on this host or to request an update from the central repository.
    1. To verify that you have the correct version of the policy on the Sudo Plugin host, run 
      # pmpolicyplugin

      Use the -g option to update the local cached security policy with the latest revision on the central repository (equivalent to pmpolicy sync on a server).
