I agree with apmcd47's direction. You can set up ssh keys for the root user. This has some security issues. As you describe it, your ssh configuration probably does not allow root to login directly, which is definitely more secure.

Your described approach with echo is not secure. Period. root passwords do not belong in scripts.

The below stuff is a model, a suggestion. You need to change it. No sudo needed.

If you do not want to undo security consider a different model from your base proposal.
Create a directory off root: /venkidhadha, maybe with 1700 permissions, definitely 700, owned by venkidhadha user. That username (or whatever name you use) has to exist on every remote box.
Leave the directory EMPTY.

Write a simple script executed by the root user's crontab, and have run once a day, or once every hour - whatever:
crontab that runs at 1:00 am once a day:

Code:
0 1 * * * /path/to/runme.shl


Code:
# runme.shl  in another admin directory  must have execute
cd /venkidhadha
find .  -type f user venkidhadha |
while read scriptname
do
    ./${scriptname} > ./${scriptname}.log_$(date "+%d%m%Y")
    chown root:root scriptname
done

The above script needs some tweaking, but you need to keep track of what has been executing, maybe send email, changing the owner to root means you cannot use duplicate script names because this:

Code:
scp $myunique_filename venkidhadha@computername::/venkidhadha

is what you execute to get the script to run as root on the remote side.

heimdal_debug

heimdal_debug(5)					      BSD File Formats Manual						  heimdal_debug(5)

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
