Hi Graham, this is unlikely to be an AppArmor issue, the usual results from AppArmor blocking access to a resource will be a Permission Denied response rather than Input/Output error.
Just in case I'm wrong though, please paste in any DENIED messages from AppArmor in your kernel's dmesg buffer.

This fails as follows: ubuntu@bastion01:~$ /usr/bin/sss_ssh_authorizedkeys [username] (Wed Mar 22 17:46:15:940434 2017) [/usr/bin/sss_ssh_authorizedkeys] [main] (0x0020): set_locale() failed (5): Input/output error Error setting the locale Further login with LDAP users is impossible. This appears to be a recent regression, a similar machine was deployed on 15 March 2017 using the same orchestration and same configuration without a problem. ubuntu@bastion01:~$ lsb_release -a No LSB modules are available.
