Please send your findings upstream. They say that this was tested with
0.3.7 and 0.4.4, so it's a bit surprising if it breaks here.

Title:
  pyasn1 error during certificate renewal

Status in freeipa package in Ubuntu:
  Incomplete

Bug description:
  moving from
  https://answers.launchpad.net/ubuntu/+source/freeipa/+question/693774

  ubuntu 18.04, 4.7.0~pre1+git20180411-2ubuntu2
  python-pyasn1: 0.4.2-3
  python-pyasn1-modules: 0.2.1-0.2

  Certmonger failed to renew certs on time and they expired. Rolled back
  the date as per various online suggestions but continually receive the
  same "903 (RPC failed at server. an internal error has occurred)".
  Apache error log shows a pyasn1 error (getcert list and apache log
  excerpt below).

  Certs are being generated and appear in the GUI under Authentication >
  Certificates. 2 new certificates are created each time certmonger
  tries. for krbtgt/MYREALM.COM@xxxxxxxxxxx and
  ldap/ipa01.mydomain.com@xxxxxxxxxxx. Notably, trying to view the
  generated certificates in the gui generates the same 903 / pyasn1
  error.
