And this is correct for FreeIPA 3.3 or later because we limit
trust to those domains we defined in cn=ad,cn=trusts,$SUFFIX with
filter (objectclass=ipaNTTrustedDomain). For the rest we return
KRB5KRB_AP_ERR_ILL_CR_TKT error code which is visible as 'KDC
policy rejects request'.
We may reconsider this check and instead of
KRB5KRB_AP_ERR_ILL_CR_TKT return KRB5_PLUGIN_NO_HANDLE to allow
fallback to krb5.conf-defined capaths but I remember we had some
issues with krb5 versions prior to 1.12 where capaths from
krb5.conf were blocking work of the DAL driver.
Alexander, could you open a ticket to prevent us from forgetting
about it?
I'm not sure yet this is valid. For FreeIPA-FreeIPA trust we'll have a
separate solution and it will be along the lines of existing 'ipa
trust-add' workflow where existing DAL driver code will work as it is.
I think we should have a way to relax this requirement, so that people
like Andreas can play with kerberos level trusts.
I agree.
Ok, then please file a ticket for this.
The change in the DAL driver will be a single line.
