It strikes me that there are two separate issues: (1) Whether or not there's a useful distinction between authentication services and directory services. (2) If there is or isn't such a distinction in (1), whether or not that distinction should appear in the implementation. In practice, people frequently mix and match authentication services and directory services, and there are services that implement one but not the other. For example, Kerberos5 for authentication an LDAP for directory services is a common combination: however, Kerberos doesn't provide directory services, only principal authentication. Likewise, even on purely local systems, the account directory services (pwent, et al) may be distinct from principal authentication using one-time passwords, etc. I'm not opposed to the fundamental idea of combining mechanism, but there are some practical underlying differences between directory services and authentication, even though there's clear overlap.
