There are time gaps in which kinit requests may fail due to offlined SSSD's locator and replication delays. Since `IPA` provider or SSSD offline the locator plugin for libkrb5 (man 8 sssd_krb5_locator_plugin) can do nothing about this and kinit fallbacks to the standard libkrb5 algorithm described in `man 5 krb5.conf`. `krb5.conf` on IPA server doesn't include `kpasswd_server` and kinit fallbacks to DNS way. DNS (URI or SRV) RRs don't preserve any order and kinit may contact either master or replica kpasswd servers. This may result in a password was changed on a replica but was not replicated to master: master(kinit)->master(initial)->replica(kpasswd)->master(can't obtain initial creds with new password) So, `kpasswd_server` serves as fallback for the offlined locator. Note: primary_kdc(the former master_kdc) doesn't help here because it is only used if the initial credentials obtaining fails (see `krb5_get_init_creds_password` in libkrb5) and not a password change.

Ground rules on adding new schema Brand new schema, particularly when written specifically for IPA, should be added in share/*.ldif. Any new files need to be explicitly loaded in ipaserver/install/dsinstance.py. These simply get copied directly into the new instance schema directory. Existing schema (e.g. in an LDAP draft) may either be added as a separate ldif in share or as an update in the updates directory. The advantage of adding the schema as an update is if 389-ds ever adds the schema then the installation won't fail due to existing schema failing to load during bootstrap. If the new schema requires a new container then this should be added to install/bootstrap-template.ldif.
