FreeIPA realm, host creation failures

Attempting to create a host fails with errors. Worked through a couple and am now stumped by this one:

2022-11-08T15:33:10 c03edbdb [W] Error details for gss_init_sec_context did not return GSS_S_COMPLETE: <GSSAPI::GssApiError>: gss_init_sec_context did not return GSS_S_COMPLETE: Unspecified GSS failure.  Minor code may provide more information
KDC has no support for encryption type

Expected outcome:
No FreeIPA related errors

Foreman and Proxy versions:
Foreman: 3.4.0
Proxy: 3.4.0
FreeIPA: 4.9.10

Foreman and Proxy plugin versions:

Distribution and version:
Foreman: CentOS Stream 8
FreeIPA: Fedora 36

Other relevant data:
Followed these instructions: Foreman :: Manual

An initial issue I faced was an error in /etc/foreman-proxy/realm_freeipa.yml. But, as far as I can tell it’s all configured as per the instructions at the moment.
