Also attaching rebased patch for ipa-4-2
Ignore the rebased patch, the original 104.1 applies on 4-2 just
fine.
Thanks, ACK.
Pushed to:

Thanks for anaysing and fixing these connection issues which were
presumably introduced by my patches. I did not hit these in my
testing. Admittedly I was focused on the ipa-4-2 branch and my
testing was mainly done there.
Brittle LDAP connection logic in install and upgrade is an ongoing
problem. What shall we do to improve the situation? Push
connection details into the Backend and let it connect if/when
needed, rather than managing connection state from the outside?
I filed a ticket: https://fedorahosted.org/freeipa/ticket/5491
I don't think we need to be smart about it, everyone just needs to make
sure that when an ad-hoc connection is opened somewhere, it is also
closed in the same place. The same applies for any other resource.
Thanks,
Fraser
Maybe it would be a good idea to implement some decorator/context
manager to connect/disconnect from specified connection and wrap the
CRUD code. Example usage:
"""
decorator:
@connected(api.Backend.ldap2, ldapi=True)
def do_magic(api, *args, **kwargs):
# do stuff
context manager:
with connected(api.Backend.ldap2, ccache=example_ccache):
do_some_other_magic()
"""
I remember Jan having some objections against this so it would be nice
to hear why this is not a good idea.
a) For ad-hoc connection objects, LDAPClient should be used instead of
ldap2. It already supports the context manager protocol:
with LDAPClient(uri) as conn:
conn.gssapi_bind()
...
I didn't know that you can and should use LDAPClient this way. We should
document it somewhere and encourage other contributors to use this approach.
b) The api.Backend.ldap2 object should be connected and disconnected
exactly once per api object per command. This is not done ATM and the
usual workaround is to connect it manually, which has lead to the mess
we have now.
Then we should find time to implement this behavior so that we can stop
shooting ourselves in the foot when messing around with API commands.
Also, only GSSAPI authentication with valid IPA user credentials should
be used with ldap2, even for ldapi connections.
