Description Petr Vobornik 2017-04-25 15:02:12 UTC 
Cloned from upstream: https://pagure.io/freeipa/issue/6876

```KerberosSession.finalize_kerberos_acquisition()``` uses ```requests``` to interact with IPA. The ```request.get()``` call performs a HTTP GET over HTTPS but fails to use FreeIPA's private CA file.

Comment 3 Petr Vobornik 2017-04-25 15:11:44 UTC 
Http code performed by this call doesn't use CA certificate/certificate store with full certificate chain of IPA server. So it might happen that in case that IPA is installed with externally signed CA certificate, the call can fail because of certificate validation and e.g. prevent session acquisition. 

If it will fail for sure is not known - the use case was not discovered, but it is faster and safer to fix preemptively.
