Description Standa Laznicka 2017-09-11 12:42:14 UTC
Description of problem:
pyasn1 >= 0.3.1 breaks syncrepl. This was discussed on the python-ldap mailing list about a month ago (https://mail.python.org/pipermail/python-ldap/2017q3/003942.html). Upstream seems to have tried to fix it but did not in the end: https://github.com/akkornel/syncrepl/commit/508f467e12e12cf80e4c0bef330d3df2a7bbd546.

This, for example, causes ipa-dnskeysyncd to fail.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Have a SyncReplConsumer object (e.g. instance of KeySyncer from ipaserver.dnssec.keysyncer)
2. Perform bind with the object
3. Prepare a search to use in polling with the object
4. Perform the_object.syncrepl_poll(**kwargs) call

Actual results:
ipa-dnskeysyncd[21447]: ipa-dnskeysyncd: INFO     Commencing sync process
ipa-dnskeysyncd[21447]: Traceback (most recent call last):
ipa-dnskeysyncd[21447]:   File "/usr/libexec/ipa/ipa-dnskeysyncd", line 116, in <module>

systemd[1]: ipa-dnskeysyncd.service: Unit entered failed state.

Expected results:
No exception on correct arguments.
