Examples--Changing Your Password

The following example shows david changing both his UNIX and Kerberos passwords with passwd. 


% passwd
	passwd:  Changing password for david
	Enter login (NIS+) password:         <enter the current UNIX password>
	New password:                        <enter the new UNIX password>
	Re-enter password:                   <confirm the new UNIX password>
	Old KRB5 password:                   <enter the current Kerberos password>
	New KRB5 password:                   <enter the new Kerberos password>
	Re-enter new KRB5 password:          <confirm the new Kerberos password>

In the above example passwd asks for both the UNIX and Kerberos password; however, if try_first_pass is set in the PAM module, the Kerberos password is automatically set to be the same as the UNIX password. (That is the default configuration.) In that case, david must use kpasswd to set his Kerberos password to something else, as shown next.

This example shows him changing only his Kerberos password with kpasswd:


% kpasswd
kpasswd: Changing password for david@ENG.ACME.COM.
Old password:           <enter the current Kerberos password>
New password:           <enter the new Kerberos password>
New password (again):   <confirm the new Kerberos password>
Kerberos password changed.

In this example, david changes the password for the Kerberos principal david/admin (which is not a valid UNIX user). To do this he must use kpasswd.


% kpasswd david/admin
kpasswd:  Changing password for david/admin.
Old password:		   	     <enter the current Kerberos password>
New password:			       <enter the new Kerberos password>
New password (again):	   <confirm the new Kerberos password>
Kerberos password changed.
