[Freeipa-users] Help with sudo permission for a command

[Ryan Whalen]

Hi All,

Im having an issue getting a command to run properly, and the issue seems
to be with Freeipa sudo permissions. Specifically 'sudo su - app_user -c
"<command>"' prompts for a password when run.

However if I 'sudo su - app_user' and then run the '<command>' as app_user,
it works fine.

example:
```
$ ssh ryan at production-server.pp
Last login: Mon Aug 29 21:36:14 2016 from 10.20.3.15
ryan$ sudo su - app_user -c "df"
[sudo] password for ryan:
^C
ryan$ sudo su - app_user
app_user$ df

ap_user$
```

I have a sudo rule that allows `/bin/su - app_user` and `/bin/su - app_user
-c` but I cant get the `-c` to work in a single command. I also tried
giving sudo permission to `/bin/bash` in case the `-c` needed it to create
a new shell for some reason, but it didn't work.

Does anyone have any thoughts on what permissions I might be missing to
allow the user to run `sudo su - app_user -c <command>`?

Thanks,
Ryan
