My IPA 2.0 master-slave setup has been working fine up until this week when
users started getting problems updating their password due to expiry. Users get
the following error when using kpasswd to update their passwords:
kinit: krb5_get_init_creds: Unable to reach any changepw server in realm
The only error I seem to find in the logs is unhelpful:
Sep 27 15:16:12 ipa1 kpasswd: Unsupported version
Sep 27 15:16:43 ipa1 kpasswd: Unsupported version
Additionally, it seems some users can reset their passwords, but the error
still appears in the logs, and on the client software:
Sep 27 15:08:52 ipa1 kpasswd: Unsupported version
Sep 27 15:09:23 ipa1 kpasswd: Unsupported version
Sep 27 15:09:54 ipa1 kpasswd: Password change succeeded
It looks like 'Unsupported version' is a reference to 'krb5_kdb_bad_version:
Unsupported version in database entry' in the kerberos software, but I can't
find any more information regarding it.
Has anyone come across this before? Is there any way to recover from it?
