Depending on the value specified for env_reset in your sudoers file, the

My sudoers file doesn't have env_reset in it, so I'm using the default
setting of it being enabled.

However, the value may be determined

I don't change/set any of these either in my sudoers file.

See the sudo and sudoers man page (and especially the SECURITY NOTES

Cross referencing each line and setting (there are hardly any) in my sudoers
file with the description from the man pages, I can't find any thing in it
that would change it.

Also, run "sudo -V" as root to see more info on your sudo config.


Running that gives me...
Environment variables to check for sanity:
        XAUTHORIZATION
        XAUTHORITY
        DISPLAY
        LOGNAME
        HOME
        TERM
        LANGUAGE
        LANG
        LC_*

Which I assume is saying that the HOME variable should be exported and set
correctly when I use sudo.  No other line on the output talks about the HOME
setting or anything regarding removing, modifying, not setting, etc... its
value.

So I'm completely confused as to what a properly configured sudo setup
should look like, as based off what you've said and what the man page states
I'm not specifically telling it to not set HOME, in fact everything seems to
imply that it should be set.

Any one else out there who has this working, could you post your sudoers
file?
Mike I assume you do have this working, do you have any extra settings in
your sudoers file?
