Just FYI, this is not strictly true, look at the -P, --password option
Thanks. I didn't notice that option since I'd been using this method since
before I started using IPA.
Is the password used to genterate a principle still usable after a keytab has
been exported? I seem to remember from my pre-IPA days of using a plain old
standalone MIT KDC that I couldn't use the password to authenticate after they
keytab had been exported using kadmin. Again, I never really investigated it,
but the password never seemed to work after the keytab was exported.
Kadmin from original MIT Kerberos has to flavors: kadmin and kadmin.local.
Only "kadmin.local" (which works locally on KDC) can export keytab without
re-generating key (i.e. password).
Network version - "kadmin" - have to re-generate key before each export.
Simo can provide details about IPA get-keytab implementation.
