Actually, there IS enough documentation on this specific subject around
(as i can recall).
In any case, this is some info wich might be usefull:
0: Read the basics of Quickstart Guide from openafs.org/documentation
1: OpenAFS uses kaserver (included in openafs's distribution) for
authentication, wich is some form of Kerberos IV.
You will make it use krb5's kdc server.For this, you should do the
i) Don't start the kaserver when configuring the database server machine
(as described in openafs's quickstart & admin guide docs).
ii) Create a principal like "afs/your_realm@your_realm"
iii) ktadd -e des-cbc-crc:v4 /tmp/afs_key afs/your_realm ( remember that
each time you use it, ktadd changes the kvno of the key)
iv) Download and build the 'asetkey' utility.I took the source from the
"openafs-krb5" debian package.Then use it to create a
keytab for afs in the format it wants to find it.( asetkey will try to
put it in /etc/openafs/server/KeyFile by default)
# asetkey add <kvno> /tmp/afs_key afs/your_realm
where <kvno> is what you get from
# k5srvutil -f /tmp/afs_key list
Now, restart the bosserver without the -noauth option.
Get credentials for some user with kinit
Try to run a bos command (something wich requires you've got krb5
credentials), and see if it complains about missing credentials.
if not, you're on your way of adding a user in afs using "pts" and
trying to use aklog to see if it gets any afs tokens for this user.
