Description Tomas Krizek 2017-03-27 14:17:33 UTC

This bug is created as a clone of upstream ticket:
https://pagure.io/bind-dyndb-ldap/issue/172

### Problem
#### What does not work as expected?
When `server_id` is not specified in the configuration file, bind-dyndb-ldap will crash when it's trying to parse the configuration:

```
named-pkcs11[19546]: cannot parse settings for 'named.conf for database dns-ldap': not found
named-pkcs11[19546]: dynamic database 'dns-ldap' configuration failed: not found
named-pkcs11[19546]: loading configuration: not found
named-pkcs11[19546]: exiting (due to fatal error)
```

This is most likely a regression caused by the API changes. The bug is *not* present for bind-dyndb-ldap-10.1-1.fc24.x86_64.

### Steps to Reproduce

* remove `server_id` from `/etc/named.conf`
* `systemctl restart named-pkcs11`

### Environment
* Plugin version: bind-dyndb-ldap-11.1-1.fc27.x86_64

* Version of BIND: bind-9.11.0-6.P2.fc25.x86_64

* Do you use bind-dyndb-ldap as part of FreeIPA installation? 
This issue happens when using bind-dyndb-ldap standalone, because FreeIPA does specify `server_id` in the default template.

### Workaround

* specify `server_Id "";` in `/etc/named.conf`
* `systemctl start named-pkcs11`

Comment 7 Nikhil Dehadrai 2017-05-02 08:22:24 UTC

ipa server version: ipa-server-4.5.0-9.el7.x86_64
bind-dyndb-ldap version: bind-dyndb-ldap-11.1-3.el7.x86_64

Tested the bug with following observations:
1. IPA upgrade from RHEL 7.2.z to RHEL 7.4 is successful.
2. IPA upgrade from RHEL 7.1.z to RHEL 7.4 FAILS.

Thus from above observation, changing the status of bug to "ASSIGNED".

Comment 10 Tomas Krizek 2017-05-02 10:11:15 UTC

The IPA upgrade from RHEL 7.1.z is a different issue, see bug 1447284.

This bug is fixed, otherwise the upgrade from 7.2.z would fail as well. I'm changing state back to ON_QA.

Comment 11 Nikhil Dehadrai 2017-05-02 10:53:35 UTC

Based on observations in above comment#7 and Comment#10, marking the status of bug to "VERIFIED".

For the IPA upgrade issue wth RHEL 7.1.z to RHEL 7.4, a separate bug BZ#1447284 is logged.
