Did you enable krb5 when you ran ./configure?

You need to do something like:

 	./configure --with-krb5-config=/usr/kerberos/bin/krb5-config

(assuming that you are using MIT Kerberos 5, with a 'krb5-config' binary 
in the given path)

I think that Heimdal also has a 'krb5-config' program, find out where it 
is and it should work.


When you get the configure script to accept the krb5 stuff properly, aklog 
should build inside the openafs tree.

This is fixed in CVS.

There is 'setkey' in src/auth/setkey.c which you can use, and there is a 
copy of asetkey in src/WINNT.

I guess you should open a bug report in openafs-bugs@openafs.org if you 
want the unix asetkey as part of the standard build.


Anyway, asetkey is just a helper program that reads the key out of a 
keytab for you and writes it into the KeyFile automatically.

You can do it manually via

 	ktadd -k /some/keytab/file
 	klist -k -K -t /some/keytab/file

 	./setkey add <key value from klist> <kvno from klist>


Okay so maybe that's a little more involved :)

I believe that the salt type is irrelevant when you are using 'ktadd'; it 
only matters for keys derived from a password string. At least MIT krb5 
doesn't care if you do:

 	ktadd -e des-cbc-crc

it will create a random key with no salt. (which is what you expect since 
the key value is random, not the result of a hashed string)

The preferred way to do this nowadays would be:

 	ktadd -k /some/keytab/file -e des-cbc-crc afs/your.cell.name@YOUR.REALM


if you have more than 1 AFS cell which share a single Kerberos realm for 
authentication.
