I'm trying to configure some Red Hat/CentOS servers to use an ipa-server on CentOS 6 for SSH authentication with public keys. I'm storing the public keys on the IPA server, which works great on Centos6 using "AuthorizedKeysCommand /usr/bin/sss_ssh_authorizedkeys" in /etc/ssh/sshd_config. However, on RH 5.10, neither the "AuthorizedKeysCommand" directive or the "/usr/bin/sss_ssh_authorizedkeys" command exist to pull the public key from the directory. Is there a different way to make this work? Googling this mostly returns instructions for setting it up on 6.
