[OpenAFS] incorrect KeyFile causing cell setup to fail -- maybe wrong enctype ?

[ted creedon]

Kadmin needs "des-cbc-crc:normal" specifically with the ":normal" suffix.

For some reason this is a change from when Ken H. wrote his monster patch
readme.

You can verify by using strace. There are previous postings on this subject.

Subject: [OpenAFS] incorrect KeyFile causing cell setup to fail -- maybe
wrong enctype ?

hi,

I am starting a fresh cell on a test box & having trouble with correct
creation of KeyFile. for some reason my notes done 3 years ago are not
sufficient, & some advice is needed!

Presumably this is due either to:
	wrong enctype(s)
	incorrect extraction method
does anybody see where I'm going horribly wrong?

thanks, Dave
