I've built the K5B7 distribution as detailed in the Installation
document dated 11 September 1996. My environment is:
DEC 5000/240 running Ultrix 4.5
gcc V 2.7.2
I've got as far as creating the krb5.conf and kdc.conf files. I then
ran
/usr/local/sbin/kdb5_util create -r OX.AC.UK -s
That went successfully, as far as I can tell, and created the
appropriate files. Next step was to do:
# /usr/local/krb5/sbin/kadmin.local
kadmin.local: addprinc admin/admin@OX.AC.UK
again, this was apparently successful.
Next, following the documentation, I tried /usr/local/sbin/kadmin but
this failed with a message now lost, but something along the lines that
it couldn't find a kadmind --- entirely reasonable, as I hadn't started
one. That's a documentation bug.
I tried again with /usr/local/krb5/sbin/kadmin.local and (apparently)
successfully managed "ktadd -k /usr/local/lib/krb5kdc/kadm5.keytab
kadmin/admin kadmin/changepw".
The file /usr/local/lib/krb5kdc/kadm5.keytab now exists and has 109
bytes in it.
Next stage (4.1.1.6) was to start the daemons on the master KDC. The
first one, /usr/local/sbin/krb5kdc, seemed to work fine and I can,
indeed, kinit myself to admin/admin with the password I chose, and get a
sensible answer from klist.
Unfortunately, /usr/local/sbin/kadmind fails reproducibly with a
segmentation violation and a core dump. A quick rummage with dbx
shows:
dbx version 3.0.1
Type 'help' for help.
signal Segmentation fault at [sscanf:114 ,0x4b52a8] Source not available
(dbx) where

The sscanf concerned is in /usr/local/src/lib/kadm5/srv/server_acl.c
line 142.
Do you have any advice on how to proceed?
Oh yes: a minor documentation bug. In the Administrator's Guide,
section "3.1 Kadmin Options" there is a typo: "... or to the username
obtained grom getpwuid, ..."
Cheers,
