Description Antoine "hashar" Musso (WMF) 2013-11-29 16:45:58 UTC 
The ssh public keys of users are retrieved from a NFS share /public/keys using in sshd_config:

 AuthorizedKeysFile	/etc/ssh/userkeys/%u/.ssh/authorized_keys

The OpenSSH in Ubuntu saucy supports a new command AuthorizedKeysCommand which would let us retrieve the public keys directly from LDAP.

Ubuntu bug:
 https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/911747

Example configuration:

 AuthorizedKeysCommand "/usr/libexec/openssh/ssh-pubkey-helper -s %u"



We can't really deploy that on our labs instance right now since they are using Precise. So I am logging this bug for later on.
