I'd like to set up pam_ldap on some of our servers so that we can centrally manage who has access to which server, and easily revoke access if e.g. someone leaves the company.

I've done some research and got this working. Hooray!

However I'd also like to be able to use public-private key logins - i.e. allow users to store their public keys in the LDAP directory and have these work for logins too.

I can't find any documentation about being able to do this, but I also can't find any reasons that it shouldn't be possible. Is there a way to do it, or is there some fundamental reason that it won't work?
