You have some other options to solve that: - SSH Key management with SKM - SSH Key DB - Openssh LPK (SSH Patch that supports LDAP) - Openssh Ldap Publickey

I believe that Openssh Ldap Publickey is one of the best options cause it does not require any patches or file syncing and it keeps the public keys in a central LDAP server.
