This is the manual process for enrolling a host running SUSE/SLE 12 SP2 with FreeIPA.

The following reference documentation was used to create this process:

• An outdated guide on Enrolling a SUSE machine with FreeIPA
• The  Manual FreeIPA guide from the RedHat documentation.

I do not recommend using yast to set this up, however it is useful to check if the configuration is valid. SUSE/SLE has all the required packages to use FreeIPA but does not have the conveinent ipa-client tools, such as ipa-client-install.
