Unable to sudo

[prince_mallow]

Modified /etc/ssh/sshd_config

added to Allow users the userx

This allowed me to log in via ssh as userx via

ssh userx@server

but sudo root returns the same
sorry, try again
3 incorrect password attempts

Since that is an RHEL-5 report and is supposedly closed ERRATA, not sure how it applies to you. Should be easy enough to check as it is an SELinux problem - [code]setenforce 0[/code]

Don't know exactly what, but I'm willing to bet that something in your security settings is killing sudo. Any way you can test this on an unmodified 4.8 install?

I emailed our VPS provider asking him about it and he directed me to a module within the WHM of our server called "Manage Shell Access"

Here it list all the users that were created using the WHM but none of the ones that I created from the shell. There are three options to set Normal Shell, Jailed Shell, and no Shell. So I logged in to the shell using the other accounts and tried to sudo and I got the same errors again.

I'm currently downloading the Centos 4.8 DVD iso and it will take several hours before the download completes itself but I did test it last night on a Ubunto distro (I had the cd available) and the first time I messed up the Sudoers file and rendered it useless, but the second time it worked fine.

Ok so I installed Sun's Virtual Box and also installed Centos 4.8 Server

I did all the steps I did before and I was able to log in successfully and issue a sudo command
