Can't su as user

Hello out there,

I can't su as normal user. Put myself in the wheel-group but still no effect.
Where is the switch to make this happen?

Thank you.
Frank

You need to edit sudoers file

You have to log out and back in before group membership changes will take effect. Also, use the gpasswd command to easily add or remove your user from groups.

"sudoers" does not exist, because I have not installed sudo.
But sudo != su, or?

Greetings

You won't have that file unless you have installed sudo. You just need to add your normal user to the wheel group, then logout and back in for the change to take effect.

e.g. gpassed -a username wheel

Use "id username" to verify the groups to which that user belongs.

Okay, if I try to do a "su -" I see this log-entry:

unix_chkpwd[9786] check pass; user unknown

Hello yabbadabbadont,

I tried this (gpasswd, it) etc. But still no effect (same error log).

Greetings,
Frank

Did you logout and back in again? If you did, and it still doesn't work, please post the output of the following commands:

id username (substitute your real user's name for 'username')

emerge --info

Hi.

No problem:
id haupt_f
uid=1000(haupt_f) gid=1000(haupt_f) groups=1000(haupt_f),10(wheel)

That doesn't look right for a normal Gentoo system. Usually there isn't a group that is the same as your user. I know that Debian/Ubuntu and the like do that, but I didn't think that Gentoo did. (Unless they changed it in the new release...)

Try adding yourself to the 'users' group. (which should be gid=100) Also, try searching for unix_chkpwd in the forums. There were a lot of results and different things to try in the few I looked at. It's 3:00AM here and I'm heading to bed, so hopefully you will find the solution in one of those threads or someone else will be able to help you.

Hello.

Okay go to bed now (it's 10.09 am here in Germany) :-)

Thanks for your help. I tested already with the users group,
but also without an effect.

Thanks a lot,
Frank

Okay, I have the solution!

emerge shadow

Maybe some permissions were destroyed. Reemerge the package fixed this.

Thanks a lot.
