[Freeipa-users] IPA-Error 903: InternalError on Certificate page

[Nico Maas]

Dear all,
I am using FreeIPA, Version: 4.8.4 on CentOS 8

ipa-client.x86_64           4.8.4-7.module_el8.2.0+374+0d2d74a1                   
@AppStream

Whenever I open the "Authentication" tab in the freeIPA webserver, I get the
error
"IPA-Error 903: InternalError. An internal error has happend".
Retry does not help, within Authentication I can use all tabs, except from the
Authentication -> Certificate -> Certificate one. This one gives the error. I can
also not search for a certificate. The other areas of  Authentication -> Certificate
(Certificate Profiles, CA ACLS, Certificate Authorities) work without problems.

As a test I cloned the machine and updated it to the latest CentOS 8 version with a newer
freeIPA version on it, but that did not solve the problem and I scrapped this vm and idea
again.

Any idea on how to resolve the issue / what could be broken? 
Which logs and things would be useful to look into?

Thanks a lot for your help and have a nice day

Nico
