After upgrading to version 6.1 you are no longer able to run 'sudo -l -U <username> after becoming root user with 'sudo su -' (4285420)

Prior to upgrading to version 6.1 the following would work even without a root entry in sudoers:
# sudo su -
# sudo -l -U <username>

However in version 6.1 the following error occurs if there is no root entry for the client  in the sudoers file:
-----------------------------
User root is not allowed to run sudo on <servername>
-----------------------------

The sudo man page states:

-----------------------------

The invoking user's real (not effective) user-ID is used to determine the user name with which to query the security policy.

-----------------------------

Under 6.1, sudo seems to using the effective ID (root user), instead of the real (login) user-ID.

STATUS:
Waiting for a fix in a future release of Privilege Manager for Sudo


WORKAROUND:
Ensure that you have a root entry in the sudoers file.

For example by default the following entry exists on most Linux systems:
-------------------------
root      ALL=(ALL)      ALL
-------------------------
