Hello the list, Here's an updated manual process for SUSE/SLE 12 SP2: https://gist.github.com/Aethylred/1a5f0eb685ce8e50b2823cda13690e7c
For the many nodes we had, we found that full registration was not required as user's were not meant to be able to login so we only implemented name and group resolution with nss and LDAP. This did not require the generation and retrieval of a keytab.
