NAME

     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-/ASL:'

	   digest-server
		sudo defaults write /Library/Preferences/com.apple.Kerberos logging -dict-add digest-service '0-/ASL:'

	   kcm	sudo defaults write /Library/Preferences/com.apple.Kerberos logging -dict-add kcm '0-/ASL:'

	   kdc	sudo defaults write /Library/Preferences/com.apple.Kerberos logging -dict-add kdc '0-/ASL:'

	   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

NAME

     gss -- how to configure gss framework

DESCRIPTION

     The gss GSS.frameworks have several configuration domains, all can configured with defaults(1).

     Configuration can be stored both in the user's configuration ( ~/Library/Preferences) and system ( /Library/Preferences ).

CONFIGURATION OPTIONS

     Use gsstool(1) to list the supported options and their settings:
	   gsstool supported-mech --options

     Common options are:

     NTLM 'Force NTLMv1'
	     Force client to use NTLMv1

     NTLM NTLMv1
	     Enable support for NTLMv1 in both client and server

     NTLM NTLMv2
	     Enable support for NTLMv2 in both client and server

     NTLM 'NTLM session key'
	     Require backends to support for NTLMv2 session key, Lion and earlier dont support this.  Session keys is required for NTLM MIC that
	     stops reflection attacks.

     NTLM 'AllowedHosts'
	     What hosts that NTLM is allowed to be used for. When there a host that is not on the list, NTLM will not be used. File globbing is
	     used when matching and it's case insensitive.  When there is no configuration, all hosts are allowed.

	     defaults write com.apple.GSS.NTLM AllowedHosts -array host.local '*.my.domain'

NTLM options
     If you want to disable NTLM support completely in both the acceptor (server) and initiator (client), you need disable both NTLMv1 and NTLMv2,
     and set their values to boolean false or 0.

     defaults write com.apple.GSS.NTLM NTLMv1 -bool false
     defaults write com.apple.GSS.NTLM NTLMv2 -bool false

APPLE MAC OS X

     You can use the defaults write command to change the options, for simple boolean options, use this:
	   defaults write com.apple.GSS.NTLM NTLMv1 -bool false

     You can also turn on debugging (output in syslog) using:
	   defaults write com.apple.GSS DebugLevel -int 10
	   open -a Console
