Kerberos key Lifetime

问题 I have a HTTP service running on my domain. But I have few doubts regarding how the life time for my HTTP service is decided. how long can a client be able to use my HTTP service ? 回答1: A Kerberos ticket has a lifetime (e.g. 10 hours) and a renewable lifetime (e.g. 7 days). As long as the ticket is still valid and is still renewable, you can request a "free" renewal -- no password required --, and the lifetime counter is reset (e.g. 10h to go, again). When creating the ticket, each "lifetime"

问题 I want to take this pattern: def accept[T](a: RList[T]) = true def accept[T, V](a: RList[T], b: RList[V])(implicit ev: a.S =:= b.S) = true def accept[T, V, Q](a: RList[T], b: RList[V], c: RList[Q])(implicit ev: a.S =:= b.S, ev2: b.S =:= c.S) = true but have it accept a KList , instead of manually overriding for all arities. Basically I want to say, "Take any number of RList s, that have the same S member type" RList is a trait, that contains a type S . (For more background on an RList and why

I installed Kerberos for Windows on a new set-up Windows 8.1 machine. Domain: not set Workgroup: WORKGROUP I edited the krb5.ini file in C:\ProgramData\MIT\Kerberos5 directory like this: [libdefaults] default_realm = HSHADOOPCLUSTER.DE [realms] HSHADOOPCLUSTER.DE = { admin_server = had-job.server.de kdc = had-job.server.de } After a restart, I made a kinit -kt daniel.keytab daniel to authenticate me against the Realm via console. Also getting a ticket by user and password via the Kerberos Ticket Manager seems to work fine, as the ticket is shown in the UI. What I'm wondering about is, that
