I've had a heck of the time getting LDAP to run on Mac OS X Server 10.3. The underlying problem has been kdc not starting so there is no way to do authenticate. I here is what I did to get kdc working... well almost. It currently is running but won't authenticate the primary user.

1. mkdir /var/db/krb5kdc

2. kdb5_util create -r TIOGA.SIERRATARN.COM -s

3. kerberosautoconfig -r TIOGA.SIERRATARN.COM -m tioga.sierratarn.com -u

4. kdcsetup -f /LDAPv3/127.0.0.1/ -a admin -p XXXXXXX -w TIOGA.SIERRATARN.COM

5. kadmin.local (create local user)

6. krb5kdc ( Start it up)

Now KDC shows running in the process list and in server admin... but I can't authenticate to the LDAPv3 Server in Workgroup Manager.
