<p class="MsoNormal">I’m seeing what feels like a concurrency error. I’m in a cloud environment and launching a group of instances which are all trying to join a domain at about the same time via ipa-client-install. Some of these operations succeed, and others
fail.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The error message on those that fail is that they failed to join the domain, and the HTTP response was 500 instead of 200.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The Apache error_log file on the server, shows a python stack trace (which unfortunately I can’t reproduce in its entirety here), which culminates in the complaint that a file (/var/run/httpd/ipa/clientcaches/<adminuser>@<domain>) was not
found. What it seems like is that multiple attempts to join the domain from different hosts are stepping on one another.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m wondering if I am trying to do something that is not supported, or if I have something misconfigured. I’m tempted to catch the error and retry after a random interval (the output of the failing command indicates that it is rolling
back to the initial state) – that would be the easiest thing. But if this is pointing to an underlying error on my part I’d rather fix it if possible.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Additional info in case it helps – I’m running RHEL7/FreeIPA4.2 on the servers (two in a replication agreement). I’m running RHEL6/FreeIPA3.0 on the clients (most recent attempt I tried to launch 7 instances, three of which failed). Thanks.<o:p></o:p></p>
