krb5-auth-dialog - Kerberos 5 credential checking

--auto If this option is specified, rb5-auth-dialogwill start only if it finds that the user has Kerberos
              credentials. This may be used to ensure that only users who actually use Kerberos see the program.
              Note that in some settings, users may authenticate to Kerberos at a later time even if they do not
              have Kerberos credentials initially.

       Probably,  but  let's  hope  not.   If  you  find  any,  please  file  them  in  the  bug   database   at

       The  krb5-auth-dialog  application  will  periodically  check (every 30 seconds) if the user has Kerberos
       credentials, and if so, if they will expire soon (in less than 30 minutes).  If it determines  that  this
       is  the  case, krb5-auth-dialog will attempt to obtain fresh credentials, prompting the user for whatever
       information is necessary.
