Kerberos kinit enter password without prompt

Question

I was looking at this: http://docs.oracle.com/javase/7/docs/technotes/tools/windows/kinit.html and noticed that it says I could use the \"password flag\". I am not sure how

Answer 1

Create a keytab using "ktutil"

> ktutil   
ktutil:  addent -password -p username@domain.com -k 1 -e rc4-hmac   
Password for username@domain.com: [enter your password]  
ktutil:  addent -password -p username@domain.com -k 1 -e aes256-cts  
Password for username@domain.com: [enter your password]   
ktutil:  wkt username.keytab   
ktutil:  quit


    # Below steps will will create a keytab for the user, move it into a secure directory, 
and automatically get a ticket when the user logs in with a bash shell

mkdir /home/username/keytabs 
chmod 700 /home/username/keytabs 
mv username.keytab /home/username/keytabs 
chmod 600 /home/username/keytabs/username.keytab 
echo "kinit -kt /home/username/keytabs/username.keytab username@domain.com" >> /home/username/.bash_profile

Command to pass keytab and login

kinit username@domain.com -k -t /path/to/username.keytab
