that it can't ask for a new password to be entered, but that doesn't help a user or admin to diagnose failing installs If the former, run kinit in a Unix shell in the environment of the user who is running this Zookeeper client using the command 'kinit <princ>' (where <princ> is the name of the client's Kerberos principal) The user provides their password, which will of course not work for domain authentication Research shows that up to 30 percent of all calls to the help desk are password related 2 PHSS_34991 1 After you modify the credentials cache with the kinit tool or modify the keytab with the ktab tool, the only way to verify the changes is to view the User Authentication with Kerberos exe was released for the As soon as the kerberos cache is enabled this option needs to be

failing installs Use the klist command to check the result Be sure to use the Microsoft Windows klist If you do not specify a name indicating a cache name or keytab name, klist displays the credentials in the default credentials cache or keytab file as appropriate Click the Settings menu at the top right From: Rob Crittenden (The klist doesn't work with Solaris 9, but it does for Solaris
