Tried that too. Now when joining the domain I get:

gss_init_sec_context failed with [ Miscellaneous failure (see text): Server
(krbtgt/LOCAL at NLI.LOCAL) unknown]
kinit succeeded but ads_sasl_spnego_gensec_bind(KRB5) failed: An internal error
occurred.
Failed to join domain: failed to connect to AD: An internal error occurred.
