Hey Jamie,
I saw the discussion about Ubuntu and sudoers on the Webmin list, but it looks like it's not working with the default way that Ubuntu sets up the admin user.
/etc/sudoers contains this line, which specifies all users in the "admin" group:
%admin ALL=(ALL) ALL
And then /etc/group puts the users into the admin group, like so:
admin:x:108:joe
I'm not sure what Webmin is looking for, but it won't let me login as "joe", I reckon it must be looking for specific mention of the username in sudoers.
Status:
Closed (fixed)
