[Freeipa-users] Change Password problems (Unsupported Version)

[Goff, Raal]

Hi,

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 EXAMPLE.COM

The only error I seem to find in the logs is unhelpful:

Sep 27 15:16:12 ipa1 kpasswd[2689]: Unsupported version
Sep 27 15:16:43 ipa1 kpasswd[2692]: 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[2630]: Unsupported version
Sep 27 15:09:23 ipa1 kpasswd[2633]: Unsupported version
Sep 27 15:09:54 ipa1 kpasswd[2637]: 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?

Regards,

-R
