Operating Systems AIX how to remove sudo access from a user ? Post 302711575 by bakunin on Sunday 7th of October 2012 04:22:57 AM

Corona is right (do NOT edit "/etc/sudoers" directly, always use "visudo"), but the real question is not "how to remove these rights", but "how did he get them in first place?"

A user having this kind of "free pass for all" - even more so individually and not via a group - looks like a severe security breach to an outsider like me. You should take away the rights but also investigate how it was possible to get them in first place - and shut down this possibility immediately.

Just my 2 cents.

heimdal_debug -- how to turn on/off debugging for Kerberos tools DESCRIPTION
The heimdal_debug kerberos frameworks have several knobs for controlling logging. The different framework knobs are: libkrb The Kerberos library, some gss-api Kerberos output ends up here too kcm the kcm library (credentials cache, ntlm client) kdc the kerberos KDC output digest-service the digest service (ntlm server) CONFIGURATION FILE
[logging] <subsystem> = 0-/SYSLOG: and watch syslog for logging information. APPLE MAC OS X
First turn up syslog debugging sudo syslog -c 0 -d then you can see the syslog output in Console.app or by running syslog -w -k org.h5l.asl To enable more extensive debugging logging for each subsystem, use the following commands: Kerberos Library sudo defaults write /Library/Preferences/com.apple.Kerberos logging -dict-add krb5 '0-/OSLOG:normal:' digest-server sudo defaults write /Library/Preferences/com.apple.Kerberos logging -dict-add digest-service '0-/OSLOG:normal:' kcm sudo defaults write /Library/Preferences/com.apple.Kerberos logging -dict-add kcm '0-/OSLOG:normal:' kdc sudo defaults write /Library/Preferences/com.apple.Kerberos logging -dict-add kdc '0-/OSLOG:normal:' MIT Kerberos Shim defaults write com.apple.MITKerberosShim EnableDebugging -bool true GSS-API framework logging sudo defaults write /Library/Preferences/com.apple.GSS DebugLevel -int 10 Other options on Mac OS X Make the admin API pretend to the server even on client sudo defaults write /Library/Preferences/com.apple.Kerberos ForceHeimODServerMode -bool true SEE ALSO
