Hello.
I'm setting up a new AFS cell using Active Directory as my KDC. When I run:
bos status mprcafs01.mayo.edu
I get:
bos: failed to contact host's bosserver (ticket contained unknown
key version number).
I've created the keys using the samba's net command:
net ads keytab add afs/[EMAIL PROTECTED]
then I deleted the two other keys with non-des-crc-cbc enctypes using
ktutil, and added the single des-crc-cbc key using asetkey. The key
versions reported by aset and kvno seem to match (see below for more
details).
I've tried the entire key creation/addition process several times to
make sure there wasn't a mismatch (deleting and recreating the computer
account in AD each time), but I don't know of a way to get AD to tell
what it thinks the key version number is (ie analog to kadmin).
Any ideas what I may have done wrong?
Thanks,
-c
Essentially what I did was:
Pre-create computer account mprcafs01 using AD Users and Computers.
net ads join "createcomputer=Research/MCR/Resources/Samba Servers --
LABS/MPRC" -S mfadir04.mfad.mfroot.org
On windows: setspn -A afs/mprc.mayo.edu mprcafs01 because otherwise
windows refuses the SPN because it's not on it's list of approved SPNs.
net ads keytab add afs/[EMAIL PROTECTED]
ktutil
rkt /etc/krb5.keytab
delent those afs/mprc.mayo.edu entries which had non des-crc-cbc enctypes
wkt /tmp/afs.keytab
asetkey add 3 /tmp/afs.keytab afs/mprc.mayo.edu
kinit works as does kvno afs/mprc.mayo.edu
