Hi,
today I found out that some entries in a keytab file seemed to have expired:
Request ticket server HTTP/mwc.linux.mydomain.at(a)LINUX.MYDOMAIN.AT
kvno 4 not found in keytab; keytab is likely out of date
Fetching the keytab again with ipa-getkeytab fixed the problem. But
why is this happening? Do keytab entries expire? I have not set any
custom password or ticket policies.
You did most likely change the key on the KDC
side by running
ipa-getkeytab at some other place. This is what kvno 4 tells you about
-- it is key version number. 4 means there were at least three different
changes since that original key issuance time already.
