[Freeipa-users] FreeIPA 4.2, CentOS 7: WebUI login "Decrypt integrity check failed" after restore

Sun Jun 12 17:13:51 UTC 2016

We restored data (just the data) from an ipa-backup on a newly-installed and configured host and with an LDAP browser we can see the data; however, the DNS data doesn't appear to be available over port 53 (selinux & firewall deactivated) and we can't login as any of the preserved users. In the httpd error logs we see output like this:

However, 'kinit username' works.
An 'ipa user-find username' fails with output like this:

[root at ipa httpd]# ipa user-find username
ipa: ERROR: cert validation failed for "CN=ipa-replica-1.EXAMPLE.COM,O=EXAMPLE.COM" ((SEC_ERROR_UNTRUSTED_ISSUER) Peer's certificate issuer has been marked as not trusted by the user.)
(snip)
ipa: ERROR: Kerberos error: Service 'HTTP at ipa-replica-1.EXAMPLE.COM' not found in Kerberos database/

And those replicas also show up in 'ipa-replica-manage list' and 'ipa-csreplica-manage list' but not if I then try to remove them via 'ipa-replica-manage del <replica-name>'.

The crucial issues before me are

1)       How do we restore WebUI login ability to the restored users, and

2)       How do we restore DNS service for the restored DNS records in LDAP?

Best regards,
Dan
