How to "su - user -c" in the same user for CRONTAB

[prodsacnetworking]

Hi,.

I need to run a script in crontab.
It needs to have all the user's logon profile (su -) but when I run in cron as:

su - user -c "command"

it don't work (asks a password)...

any idea?

TRY : su -l user -c "command"

And I think you must be root in order to be allowed to use su in the scripting format in this manner. Just like on the command line, root can su to someone without a passwd. Going in the other direction from user to user will always require a passwd, unless you take the passwd out of the passwd for the user being su'd to.
From user to root via cron is a security breach. I believe it was still available in the late 1980's on SUN version 2 or 3, before Solaris, before the internet existed.

Another idea: How about a dummy user that has the cron script in question launched from etc/passwd . The shell has to be defined in /etc/shells along with all other valid shells.

Or add a crontab for the user in question and it runs under user in question with out the su.
