[Discuss] tcsh, AD, and RHEL 5.6

2012-09-07 Thread Scott Ehrlich
I have a RHEL 5.6 workstation configured with samba3x to authenticate to a Windows 2008 AD environment (net ads join) so the workstation appears as a Windows box that has joined the domain. Now, any user can ssh into it with their AD credentials, and /etc/passwd has no knowledge of their

Basically I am of the walking away and not bothering variety. I think that in an enclosed office environment with coworkers, this lapse of security is ok. A coworker of mine in Toronto got gigged a couple of weeks ago because he did not comply with the security policy and either left his laptop

To elaborate a bit, Project Athena doesn't use encrypted home directories but it does use Kerberos and AFS to provide a degree of security. Even so, there is a formal policy of 20 minutes away from a workstation: If you are using a workstation in one of the Athena clusters and intend to keep

I think it is a bad practice to symlink (or hardlink) /bin/sh to bash, especially on a commercial Unix system. Basically, the Bourne Shell and the BASH shell have different behaviors. You are much, much better off installing the BASH shell on a commercial Unix system. On 09/07/2012 03:09 PM,
