Nope, running with strace lets us use the IPA command again with impunity. 
Without it, process termination.


A theory. Your data has some output that is treated as escape sequence that crushes the shell so your connection is closed.
Do you test it with the same command all the time?

Have you tried other commands?
Can you do a user/group/host add?

Can you try other commands?

I then found this pattern occurring a number of times within the (17564

Just noise while we fork off and run another process, in this case keyctl to 
store the session cookie in the kernel keyring.

So running with strace doesn't result in the session logging out?
